This light spectrometer (more accurately “spectrophotometer”) connects to your PC via USB, using Theremino free software, or to Linux or iOS using SpectralWorkbench. It is suitable for analysing IR, UV and light sources by collecting and displaying their spectra. It had a bandwith of typically approximately 400 – 1000 nm (nano metres) and often significantly better. So it can see near IR and UV as well as all visible light. And it’s accurate to +/-2nm or better Explore the world of light science. Test LEDs and lamps, measure transparency of coatings and sheet materials, analyse substances through absorption spectra, etc.You can see a dynamic graph of wavelength against relative intensity for your light source, though you cannot measure absolute intensities (lux or photon flux density, for example). Indoor Growers / Hydroponics: Test your grow lights (grow lamp tester) & membranes for PAR coverage & take actions driven by your own scientific analysis Amateur Scientisits: explore light science / Raman spectroscopy etc.Astronomers: Can you collect enough light to do spectral analysese? Educators: Bring light science alive!

F U R T H E R I N F O R M A T I O N FAQHi, I am a dark skies educator, and I am looking for a reasonably portable spectrograph or spectrometer that I can use to measure the blue light being emitted from LED street lights of 3000K+. Would this model be abke to do that, or am I going to have to look for some a tad bit more expensive? Thanks – Hi ***, It’s difficult to say because it depends how bright and how far away the street light is from the instrument. I have a video showing me collecting the sodium spectrum of a street light opposite my office with my i-Phos on my channel here: .https://youtu.be/Tz43jRf8FjY?t=352 – but I think I used the interchangeable slit plate model with a 5mm slit plate. To be on the safe side, I would recomment that version. The Pro Bundle includes all 6 slit plates from 0.5 to 5mm, and you can remove all slit plates for an even wider aperture. If you’re on a budget, then you could also modify the front end cap yourself – slit plates are low-tech devices – but you’d need to ensure that the plate is aligned rotationally with the camera or your spectral lines will be tilted. Another option for you is to buy the cheaper version and try it – and if it is not suitable for you, contact me again and I can sell you the interchageable slit frame and you can replces the old one. I would also be interested in working with you to see if you can get the i-Phos to produce good spectra from sky objects like the moon or a bright star. I’m sorry my answer isn’t a solid YES or NO, but I hope the advice and options offered are helpful for you. Best Wishes Chris Hello, I want to know if is possible use it for get the ink spectrum on documents? And if is possible get better price if a order 5 pieces Thanks for your comments ***, I have not tried to get spectra from ink but this would be done using the absorption method. Shine a white light on the ink and measure the reflected light looking for absorption lines which would chracterise the composition of the ink. So, in theory, it is possible, but in practice I have not tried it. Sorry, there is no bulk purchase discount. Will this measure PAR ? It’s complicated. PAR is an achronym for “Photosynthetically Active Region” – that range of wavelengths of light which promote photosynthesis – the process plants use to live and grow. A PAR Meter measures light intensity – or “flux density” – the amount of light landing on a certain area per second. PAR meters will have filters but they don’t usually measure the specific wavelengths of light – just the intensity. So, for example, your PAR meter won’t “know” if your light source completely fails to deliver some wavelengths which are important in fruiting. This instrument fills that gap – it measures the wavelengths and their relative intensities, so you can see which wavelengths (colours) are being delivered, and which are not. That knowledge allows you to take action (changing or adding light sources) for optimal performance. Sorry to trouble you. Do you actually mean UV-VISIBL and not UV-IR Spectrometre? The spectrum chart indicate the former. Thanks. You’re not troubling me -thank you for your question. The sensor can see wavelengths from about 380 to 930 nano meters, which covers near infraread, visible and nea ultra violet wavelengths. Hello is it compatible with windows 7 ? can I study filter transmission, like multigrade silver print filters ? Best regards Hello, Yes, the software should work with Windows 7 and back to Vista! Yes, you can study filter transmission. bear in mind that the software shows a real-time graph of wavelength against relative intensity, but not of absolute intensity. So you cannot measure flux density, for example, but you can easily see visually what your filter is doing to your light source. Best Wishes Chris I would be grateful, for any information about utilizing this spectrometre in the field of gemology, especially the Raman spectroscopy. Thanks. The short answer is “I don’t know”. Ceretainly, the i-Phos will analyse the spectra of light sources, but Raman spectroscopy relies on analysing the 1% of light from Raman scattering, so the intensity might be very low. If you can arrange for all of the light to enter the spectroscope – maybe by removing the front aperture and using a long integration time, you might get a good spectrum, but it’s not something I’ve tried to do. Hello, is the software also part of the auction? If yes, which system requirement does the computer need? With friendly greetings Hello. Yes, the software is included. I sent a download link when shipping. This software runs on a Windows PC. greetings Chris Hi Chris, I had a lot of fun with it yesterday, and I sent my friend on discord many graphs! I noticed that the exposure setting can make a significant change to the graph. Is there a good rule of thumb for ensuring it’s set to the right value for the thing being tested? Regards,Paul Hi Paul, the i-Phos is a compromise – for less than 1% of the cost of a lab insrtument you get a lot of functionality but you don’t get everything. So the i-Phos displays an approximate relative intensity graph for the wavelengths of the source. This is explained in the sales literature. The i-Phos is perfect for checking the central output wavelength of power LEDs lasers etc. but it’s not ideal for relative intensity measurements. Even so it’s still very useful. See the comparisons between i-Phos charts and Ocean Optics lab instruments on my channel – they are almost identical. As you point out – in some cases, the relative heights (intensities) of wavelengths change with exposure – and they can’t all be true! How you accomodate this depends on the objective of your analysis but in general, avoid saturating the webcam sensor by dialling down the exposure to keep peaks away from the top of the graph. If you are only interested in part of the spectrum then adjust exposure so that THAT PART of the spectrum has the right exposure – not bumbling on the X axis, but not smashing the top either. Fundamentally the webcam sensor should be kept out of the noise floor and saturation regions. It will take a little time to get to know your instrument and how to get the best from it. Ultimately, rest assured that if you’re not happy – you will get your money back! Best Wishes Chris Customer Comments I’m a Lecturer in Physics at Lancaster University. [UK]I thought I’d take the chance to drop you line and congratulate you on your brilliant i-Phos spectrometer! I’ve purchased a couple of them over the past year, with the intention of using them for educational purposes. I previously spent a couple of years searching for a spectrometer that was accurate, practical and affordable – so it was great to discover your product!The ongoing lockdowns have prevented me from doing much so far, but I was able to point one at a hydrogen lamp, and produce the attached spectrum, which looks excellent (I suspect my spectra will look even better once I’ve learnt how to get most out of these devices). I have lots of ideas for when normality finally returns to our labs, lecture theatres and classrooms.Dr. Andy BlakeLecturer in Experimental Neutrino PhysicsLancaster University, UK (made public with Dr Blake’s kind permission) The i-Phos HD 370-950 nm Light Spectrometer is an inexpensive instrument for those of us who don’t need a professional unit to measure wavelength and to date is one of the best deals I’ve found on the net for use in my laser hobby. Read the comprehensive & independent review here!Chris H, Laser Discourse forum admin This thing is great. Thanks for putting it on EBay at a very affordable priceMike, USA I have tested the spectrometer and it works as easy as I have hoped. Thank you. Nico, Netherlands Hi Chris a big thankYOU ( or as we say in some parts of Oirland ‘Go Maith Agat ’) for a brilliant product, great delivery, customer service, and empowering me with a superb instrument to see the world with so many colourful and ‘non visible to the naked eye spectrum’ possibilities too. Enthused and thankful. Cheers ( I admire Great British designers like you), Sean, Co Meath, Ireland [I] just wanted to let you know that I received the Spec[trometer] all in good order and I have played around with it a bit and I think it is excellent – really happy with it. Im using it for various things including looking at LED grow lights , confirming the wavelength of some gadgets that I got from China but was never sure of how accurate they were, and things like that – I realised it can be a very useful tool to have around and was going to build it myself but you had worked out all the details so made more sense to get it from you. Anyway, just wanted to say thanks and will let you know if I think of any upgrades with it in the future. best wishes Antoine, Ashord, UK Oh my God! I’m loving this. … it all works automatically without any manual downloads on my Windows 10 PC. I will be studying for days the light from various devices. THANK YOU CHRIS! You have saved me potentially thousands. And hopefully I will be able to better understand the nature of my eyes sensitivity. FYI, I will send you some snapshots of the white screen from various monitors. When I get a laptop I will be able to analyse the light from more monitors.Hooray!U.R, Australia Hi Chris. I have the spectrometer working here now. Really good, I’m very pleased. Very many thanks, Steve, UK Chris, just fired up the spectrometer and software, 10 mins and its running. Just taken the spectra of a UV torch, fluorescent and filament lamp. Truly an amazing piece of kit. I thought of getting an optical spectrometer like at uni but this was the most cost-effective. Solar spectrometry is next on the weekend. I found you on Amazon, it’s great to have this artisan industry in the world and accessible to all. Regards Misha, UK The spectrometer is amazing, it actually works much better than our old (and expensive) Vernier spectrometer! I already got a very good spectrum of the sun, after just a quick calibration. The spectrometer will be used in a workshop for students about atomic physics that we offer [here]. So far I’m not sure what we will look at exactly, but I already see lots of possibilities! Thanks again! Best regards Charlotte, Switzerland Hi Chris, Just wanted to let you know that I got it now and already tested it. Cool device! I like it very much. Regards Andreas, Switzerland Hello Chris The i-Phos is arrived in Switzerland and works very well. Horst, Switzerland Hi Chris, Just just to let you know I recieved the Spectrometer today and it works like a charm. Thanks again! Nico, Switzerland Thank-you for your great job Daniel, Belgium Hi Chris, now I was successfull and the spectrsocope works well! Compliment for this development – great! Many Thanks for your advice and patience Best wishes Wolfgang, Germany Hi Chris, It’s arrived! I’m using a small tripod (that I forgot I had) to keep it steady on my desk. It looks awesome. It’s even better than I expected. […] I managed to have a quick play at lunch time. Calibration wasn’t as complicated as I feared (even though one of my cats moved the tripod while I was trying to calibrate!)! I have to say it’s a fantastic product, so much better than I expected. I’m going to have a lot of fun with it. Regards, Paul, UK Hello Chris ! nice to meet you. I got your nice spectrometer some days ago. I just had the time for a quick test, It is great and it perfectly fits to my hopes. Cheers Domi, Belgium Hi Chris Thank you for all the detailed instructions. I just found some time yesterday to properly calibrate the i-Phos and test it.It works like a charm. 🙂 Alexander, Switzerland Hi Chris, I am very pleased with the i-Phos I purchased before Christmas and would now like to fit a tripod mounting bracket. Please advise how I can purchase the bracket as a separate accessory and the extra cost for postage and packing. Regards, Eamon, UK Hi Chris,I received the spectrometer yesterday and it works like a charm. Thanks!I intend to primarily use it to test and verify various red and near-infrared light sources for photobiostimulation.Best Regards from Denmark Kristian
