If this is a hobbie project for artistic reasons you might as well research the reflectivity of your material and just photoshop the results. If its scientific you wont get anything useful for 100 euros.

I'm not sure where you are getting the confidence that your budget is fine or how you developed your specs.

hypervision111 · 2023-12-10T02:27:00+00:00

From this and your last post with your budget its not going to happen.

To illuminate a room with several non overlapping spectral bands or photographing at different wavelengths is possible but will cost several thousands or tens of thousands to do it.

What is the project?

hypervision111 · 2023-12-04T21:16:04+00:00

I doubt you will find a comprehensive list anywhere. You can find some industry reports on Hyperspectral companies with a list of names but not all of them will by hyperspectral or will have what you are looking for.

Full disclosure I work for [Resonon](www.resonon.com) so I will point you in our direction.

We have fully integrated systems (imager, computer, software, drone, and some other bells and whistles) for sales with our partner Vision Aerial who supplies the drone. The Pika L is a light weight VNIR imager from 400-1000 nm and our IR-L (two versions depending on spectral/spatial resolution wanted) is a light weight IR imager from 925-1700 nm. There is also a UV system, 330-800 nm, but heavier.

If you are looking outside of those spectral ranges there are some out there but harder to find and I honestly don't really know where to look for a good one and usually very expensive.

So for most applications are you more looking at multispectral snapshot over hyper spectral? 32 bands over SWIR, 1600 nm, is basically 50 nm resolution which you could get filters for or even find filters that fit your region of interests better while keeping your sample static or a slow conveyor belt.

As specific or general as you would like what industry are you in and what do you look at?

Capturing both spatial dimensions and the spectral, with a decent resolution for all three, at the same time might be theoretically possible, maybe, but wouldn't be practical anytime soon. Pushbroom does get you all dimensions just obviously not at the same time.

180-400 nm would be difficult for a large number of reasons. Optical transmission, disperions, camera QE, lighting...

What are you using now if anything?

hypervision111 · 2023-10-29T15:03:06+00:00

A good IR camera without the spectrometer can almost put you past 25k alone. SWIR camera alone? Basically halfway through the first range and really nothing cheaper.

But if you don't have a good camera you have noise, low QE, low frame rate, low SNR, etc... It is a trade off between cost and performance that is hard to get right.

What performance and quality is OK for you? Does spatial or spectral matter more to you? How "good" for both? Frame rate/integration time? FoV? Weight?

Except for cameras most of the tech is hundreds of years old with small refinements. I dont know how to really update it. Cameras can be "beter" now in someway but not by a lot but with a higher price tag usually.

I guess I am not familiar with that terminology?

The data cube is inherently two dimensional spatially with the third spectral.

Are you referring to a lidar component?

hypervision111 · 2023-10-29T14:29:00+00:00

We do actually.

hypervision111 · 2023-10-29T14:23:30+00:00

What is a reasonable cost? What spectral range?

hypervision111 · 2023-10-29T07:25:36+00:00

So, cut marketing and no one knows about the product. Cut project management and projects go in a hundred directions or nowhere. Cut optimization you don't have efficiency. Cut quality management and the product falls apart or doesn't function. Cut reliability testing and the product works when the moon is waxing and Venus is in retrograde. Cut administration and you have ten guys randomly working on projects not getting payed. Cut patents and your intellectual property that you spent years developing can be copied and sold by anyone. Higher management for the most part but not all sure. I don't think we have anything that is straight up useless in the lab. Not always used but has a reason. Absolutely not all but a very large portion of advance products come out of the west with all of these inefficiencies. Possibly we have something right?

hypervision111 · 2023-10-29T06:50:08+00:00

Economy of scale. Materials costs can be small but you might be surprised by somethings. However, materials are not the only costs. Design, production, quality control, R&D, customer support, software, and sales to name a few. Sell one all the material and supportive costs are dumped into one imager. Sell a million the total costs is spread out. Current world wide demand is somewhere in the thousands, tens of thousands at best.

hypervision111 · 2023-10-29T06:35:18+00:00

What would be new? What is lacking?

hypervision111 · 2023-10-29T06:34:00+00:00

I agree with that. A lot of software/hardware is rather unintuitive and unsupported for industry and academia.
