And in the other direction, polyethelene DIY plastic lenses! Of course sometimes one can find a focus/zoom military germanium lens on eBay, pricey but cheaper than a Fluke or Flir camera. Does Lepton use silicon? If so, then one experiment would be to pry off the lens and substitute it for a $100 version (often seen on eBay, I have a couple of those.) I don't know if this will improve it, since a very small (thin !) lens of Si might have insignificant absorption. Note: germanium lenses are less absorptive than silicon lenses. See youtube examples on my thermal vids page, about nine videos down.

I suspect that the professional versions use two imagers behind one lens, one with a narrowband IR filter on the hydrocarbon IR absorption line, so they get a large difference-signal. Subtract the video streams, adust bright/contr, then present a gasoline rag to just one camera's view. Or a realtime version: two adjacent Lepton kits 50cm apart, adjusted to aim at the same distant background.
Then hold up a gasoline-soaked rag, see if hydrocarbon vapors show up. The quick/dirty version would be to record and store a background image, then subtract it from a live image, crank up the contrast. I think those devices work at around 7u wavelength, so Lepton might work if the dynamic range is large enough. I wonder if these can be used in a "gas fumes" camera, Gas FindIR(tm) or similar? they aren't losing any money on E4s and they sure as heck aren't losing anything on the E8s ( if anyone is even still buying them). Even though the one sensor costs slightly more to manufacture than the same quantity of an 80圆0 sensor would, they couldn't sell that large quantity of such a crappy sensor. Much more efficient to have only one, and the more of one single product you manufacture, the cheaper that one part becomes to manufacture. If flir were to offer the E-series cams with 4 different sensors, they would need to engineer 4 separate products, and they would need 4 separate manufacturing processes. Its the engineering, and its the manufacture setup. It isn't so much the manufacture of the sensor that costs the most money. "seems highly unlikely" - yeah, it does, until you spend a minute in deep thought about it. Imagine how customers who paid 4k for the E8 feel when they find out they overpaid by 3k.
It isn't something that flir really wants people to know. you won't find this information freely available on the flir website or their distributor's websites, so stop researching there. When inserting it into the breakout board be sure to use proper personal grounding, such as a grounding wrist strap, to prevent damage the module. The Lepton® module is extremely sensitive to electrostatic discharge (ESD). Note: This kit comes in two separate parts and will need to be assembled once received. A few things to consider about this kit: the breakout board will accept a 3-5V input and regulate it to what the Lepton® wants, to read an image from the lepton module all you need is an SPI port, and to configure the camera settings you also need an I 2C port, although this is not required. Meanwhile, each breakout board in these kits provides the socket for the Lepton®, power supply's, 25Mhz Crystal Oscillator, 100 mil header for use in a breadboard or wiring to any host system. The Lepton® LWIR module included in each FLiR Dev Kit acts as a sort of camera and packs a resolution of 80 × 60 pixels into a camera body that is smaller than a dime and captures infrared radiation input in its nominal response wavelength band (from 8 to 14 microns) and outputs a uniform thermal image.

All you need to do to get this kit set up, simply attach the Lepton® imager module into the provided breakout, connect the headers, and you will be seeing in full darkness in no time! With this kit you will be able to bring FLiR's thermal imaging reliability and power to your Arduino, Raspberry Pi, or any ARM based development tool all in an easy to access breadboard friendly package. The FLiR Dev Kit includes a breakout as well as a Lepton® longwave infrared (LWIR) imager.
