All parts of the electromagnetic spectrum are covered now, including gravitational frequencies

Chad, I asked about 14 microMeters which is LWIR “thermal”.

Breaking up the electromagnetic spectrum into tiny market segments is counter productive.  The real gains come from when the whole spectrum from below nanoHertz to above ExaHertz is covered.  I use ElectronVolts a lot.  It is even better.  And there are groups working from femtoElectronVolts to TeraElectronVolts.  And well outside that range to smaller and larger.  I cover all that for the Internet Foundation.  Here is the device you just linked to. and where I was looking (LWIR) and where else I am working right now.  “Thermal” has many markets itself. But the one growing the fastest is “near room temperature” and “biomedical” and “everyday temperatures”.  But no part of the spectrum is being ignored for imaging now.  I am aiming for “soft x-ray” and “extreme ultraviolet” where most gravitational effects lie.  But I am not ignoring anything.

I try to become familiar with all sensors. Many reach “global scale” and turn into “new global industries”, no matter how tiny their beginnings.  Those create new jobs, new corporations, new industries, new global issues and opportunities. The names around 1 micron keep changing because of marketing. That is counter productive.


Chad, I appreciate your persistence, but the field of LWIR is changing dramatically these days.  Imaging arrays are getting less expensive, faster, smaller, more precise, easier to adapt – quickly. I am aware of most all kinds of detectors for all purposes.

The Internet has countless ones and many hundreds of small groups who can build most anything you want. What I try to find are the ones who will emerge as new global industries – affecting the lives of the 8 billion humans now.

Without a huge investment of time, these low cost modules and components can be adapted to many new purposes. But the market is driving them to the applications I mentioned. ThorLabs seems to have the ability.  I am not sure if they are fast enough and willing to do the work.  I am not starting new industries myself.  Perhaps some of the soft x-ray and extreme ultraviolet, some thermal.

I asked ThorLabs about LWIR and thermal microscopy – partly to encourage you to try.  Not for me, because I cannot afford your prices, which are predicated on an older way of doing things.  With AIs, in a year or two, it will likely change dramatically.

For PDA10DT, you should probably write the bandwidth as 1 MHz. PDA10D2 as 25 MHz.  PDA10PT as 1.6 MHz. And put in data for PDA13L2 to see why it is so slow.

You can put in an extension to show eV, Kelvin, Hertz, mm and other energy units.

You have a lot of good stuff, but it is not in a form easy to use for the newer groups.  Thanks for the link.  I can only evaluate those NIR and SWIR sensors with a LOT of data, and you are at the component level still, or too narrow application.
