LinkSquare SDK Handheld Spectrometer

Discover the many layers of the world with the LinkSquare SDK Handheld Spectrometer by Stratio. This device comes with software to collect a multitude of data for objects all around you. Additionally, LinkSquare can collect exact color data of virtually any object you can find. In addition, it uses near-infrared light to help determine the molecular makeup of objects. If that wasn’t incredible enough, LinkSquare can even help you distinguish between genuine and fraudulent products, like gemstones or medication. It works by capturing how objects respond to different light. You can visualize the data you collect within the SDK or you can export it to third party software for in-depth analysis. The device comes with everything you need, including the USB charging cable and software. You can combine LinkSquare with your programming and data analysis skills to conduct research, develop apps, or just fulfill your own curiosity. Free international shipping upon request!

Connection problems and application crashes were solved after updating the software to v1.0.2.

I received my stratio sdk, but I've not been able to make it work. I downloaded the APP installation sdk for Windows, but whenever I try to connect it (wether using APP mode or IoT mode), it just says no device was found. Also, whenever I try to use the FAQ or the help from the program, it crashes and closes. :(

@Kean Alas! We're sorry to hear this version won't do it for you, but hope a future version will suit your needs. Thanks so much for the kind words and for sharing the campaign with your colleagues!

@creator Thanks for the extra technical info. Unfortunately this would be no better for my applications than what I already have access to. It does look much more useful than the SCiO, I have two of the early ones and don't really use them.
Good luck with the campaign, I'll keep my small pledge and follow along. I will also mention your campaign to some colleagues.

@Javier Sanchez Hi! Whether LinkSquare can detect something depends in part on whether the wavelengths it uses (450-1000 nm) are suitable for detecting the material in question. There is a wide world of pesticides and poisons out there to explore, so more research would be needed. Also important is how high the concentration of the pesticide/poison is. LinkSquare likely wouldn't be too effective with very small concentrations or particulate matter, but larger amounts could be doable. We think this would be a great thing to investigate with LinkSquare, and we hope to do more work in the area soon. Thanks for your interest!

@Kean Hi! Thanks for your questions. The LinkSquare uses an off-the-shelf silicon sensor and collects >600 data points per scan. As for resolution, it is ~15 nm, but could vary a bit by wavelength. We recently tweaked the optical system to bring this number down from ~30 nm, so we're pretty excited about it. Finally, we don’t use an excitation source like a Raman spectrometer would – rather, we shine broadband light and collect data from the reflection. Hope this helps!

Will it be able to detect dangerous substances, like pesticides or poisoning materials?

Review from Kickstarter
@creator Your "nitty gritty" specifications are a bit on the light side. Do you have a specification for spectral resolution or a response graph? A range of 450-1000nm is great, but not useful if the sensor doesn't resolve a reasonable number of data points in that range. Is it using a commercial sensor, or your own? Do you have any other data on the sensor? Does the unit provide an excitation source for measurements, and if so what wavelengths?

@John Vanderlans Thanks for your questions! LinkSquare utilizes both visible and near infrared light. This means the data collected goes beyond color alone to molecular composition. Based on our experiences, though, we think that doing what you describe with metals would likely be difficult. However, more in-depth study would be needed to know for sure.

Review from Kickstarter
@Eric I think the shape would be best described as sort of like a rectangle where the height is less than .1 mm and the width is slightly smaller. As for the battery, it is not replaceable by the user. However, we use a standard lithium battery and haven't had any issues with it in our test units. Hope this helps!

Review from Kickstarter
@creator Thanks for the answer! Did you mean .1 mm^2 area or circular area of .1 mm diameter? Another question: Is the battery of the LinkSquare user-replaceable?
I am asking because I once had a quite bad experience with a portable spectrophotometer whose battery died. Unfortunately it was a built-in battery that was not user-replaceable and the cost of shipping and repair at the manufacturer was north of 300 USD.

Review from Kickstarter
How precise is it? Could it tell the difference of 22 and 24 karat gold if they were formulated to be the exact same colour?
John Vanderlans
Review from Kickstarter
Does it analysis by colour alone? If you had 2 pieces of metal, would it tell you the elements it is made up of?

Review from Kickstarter
@Eric Thanks for the kind words! The measurement area on the surface of the object is less than .1 mm.

Review from Kickstarter
@creator Hi! Awesome project! If you place the spectrometer tip at, say, 5 mm distance from the target, how large is the measurement area (or diameter) on the target surface?

@Jesus del Valle Yes, we do international shipping upon request. I messaged you with the information, but let me know if you need anything else!

@Athavan
1. Yes, in general, taking multiple samples and averaging the measurements will reduce noise and give a better signal.
2. We have found that scanning liquids works best when the liquid is not transparent.
3. We recommend a distance of around 5 mm between the tip of LinkSquare and the object.
4. You can use an alcohol/water wipe to clean the tip, but it is best to keep it as dry as possible. Definitely not a good idea to submerge the tip in any kind of liquid or cleaning solution.
5. We recommend using a cuvette with a flat surface if possible. However, if you maintain a distance of around 5 mm and the liquid in the cuvette is not transparent, the effect of the curvature should be negligible.
Thanks!

Review from Kickstarter
Thanks for the clarification. Can sensitivity of the measurement be improved by taking and averaging multiple measurements? Also, what are the limitations to scanning fluids? How far should the tip be from the surface? Can the tip be easily cleaned with water or isopropyl alcohol? Will the curvature of a cuvette or vial distort the readout?

Review from Kickstarter
@Athavan - In terms of the hardware, a main difference between LinkSquare and SCiO is that LinkSquare collects data from both the visible and near infrared (NIR) portions of the light spectrum. SCiO only covers NIR.
Another difference is that we allow SDK users to directly own and access all the data they collect. We heard from a lot of researchers and developers that this was important to them, so made it a feature of our product.
Hope this helps!

What benefits does the Linksquare SDK offer over the Consumer Physics' SCiO?

Review from Kickstarter
Hi. We met when you visited Bayer Grants4Apps in Berlin and pitched your awesome project. I wanted to buy one of your spectrometers, but you only ship US or Korea. I live in Germany, I could ask for addresses of my friends in Korea or US. How can I buy one? Can you make an exception for me? Thanks & keep up your good work!
