the i-Phos can do:
From only £74, the i-Phos
Light, IR and UV spectrometer is an affordable entry into professional-standard
light, IR & UV spectroscopy.
The i-Phos can see wavelengths from approximately 420 - 980nm and their relative (though not their absolute) intensities. You can analyse sunlight, moonlight, indoor and outdoor light sources, grow lights (LEDs, CFLs, HIDs, etc.) - light spectra from anything.
You can configure the instrument to perform absorption spectroscopy, for analysing oils etc.
The software provides sophisticated features to make using your i-Phos a fascinating pleasure, yet it's really easy to just plug in and get started.
Full software documentation is provided.
Who is i-Phos For?
Horticulturalists, professional or otherwise, can use the i-Phos to design and then maintain the perfect lighting setup for their needs - in terms of the emitters and the transparency of their enclosure materials.
Educators in schools, colleges and universities will find teaching light science with the i-Phos easy and fun.
Parents will find the i-Phos a real asset for their inquisitive children to explore light science.
Scientists, at work and at home, will find the i-Phos, with its 1nm accuracy, just as capable, in many ways, as scientific instruments costing 100 times as much.
Whoever you are, diverse fields of application could include astronomy, Raman spectroscopy, oils analysis, flame analysis, checking LED and laser calibrations, and much more.

What my Customers Say
I have tested the spectrometer and it works as easy as I have hoped.
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),
[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.
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
Oh my God!
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.
Hi Chris, Just just to let you know I recieved the Spectrometer
today and it works like a charm. Thanks again!
Thank-you for your great job
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.
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.
Thank you for all the detailed instructions. I just found some
time yesterday to properly calibrate the i-Phos and test it.
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
Thank you very much for taking the time to update me and also for the excellent manner in which all of your communication and detailed information regarding this product. Your professionalism is a credit to yourself and is greatly appreciated.
... I started to use it with my students, and it's one of my favourite tool ! Thanks alot for your explanations, and your time.
i-Phos Questions & Answers
Can you extend the range of wavelengths it can see?
No. The sensor is based on a webcam designed to see visible light. With the IR filter removed it can see a little beyond that into both UV and IR but not far and it can't be extended further.
Can it measure blue light?
- Hi ***,
It's difficult to say because it depends how bright and how far away
the street light is from the instrument.
- 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.
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 replace 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.
Can it analyse inks?
Hello, I want to know if is possible use it for get the ink spectrum
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 & Intensities?
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 1000 [now 930] nano meters, which covers near infraread, visible and nea ultra violet wavelengths.
Does it run with Windows 7?
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.
Can it do gemology?
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% or 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. Yes, the software is included. I sent a download link when shipping. This software runs on a Windows PC.
How do I set exposure correctly?
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?
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
