Klein TI250

[jmw]

Has anyone used one of these? It's $300, evidently 320x240 (not sure if that's the sensor resolution or the output image resolution - spec sheet says "10800 pixels" but an Amazon reviewer says the images are 320x240). I'm curious if it's a Seek OEM sensor, if so that seems like a good price and I'd love to have something standalone even if the form factor is a little weird.

It uses a Wuhan Guide TIMO core with 120 x 90 pixels.

The Core Information is here…..

Chinese companies are producing some interesting new thermal cores for consumer and medical applications 

InfIRay have their higher resolution Tiny1 series

Wuhan Guide have their own pocket camera design that uses the TIMO core. I prefer it in terms of case design……

I found these Timo cores available from suppliers with USB carrier boards for around $250ish in 1-5 unit qty, might order a few to screw around with.

You might do better to buy the InfIRay S0. If you want miniaturisation they offer the Tiny1

Infiray certainly do have some interesting cores. They are publicly admitting to 1024x768 14µm pitch 30Hz uncooled LWIR but I wouldn't be at all surprised if they aren't a step ahead of that for their *cough* private domestic customer(s).

So, is it just me or are the US export regulations looking more and more irrelevant? Unless of course you're a US company that isn't allowed to export things that are freely available in the rest of the world?

They are also making 10um pixel microbolometers…….

IRay appear to be using a similar ‘thermal collector hat’ on top of each pixel, as used by DRS on the Tamarisk core.

1280 x 1024 pixel core…. Approx $22K in quantities of 10 or more…..

The Worldwide Pandemic has driven Chinese development of microbolometers and also lead to higher production umbers that reduce the price to OEM’s. Major World events have a habit of accelerating technology development but often, sadly, it is War rather than a Virus.
