content: Finally decided to pull the trigger on something to upgrade my hacked Flir E4... picked up theInfiray M600. Still trying to see what I like and don't like about it, but reasonably happy overall so far. Same brand who make thepopular cheaper handheld models. Except this one is 640x512 @ 30Hz! And has both a nice manual focus ring and a tripod screw mount, which makes it pretty convenient for electronics work.I am hoping to do a bit of a video review / comparison of a few thermal camera models I own when I get a chance... trouble is I rent them out on the side, so I don't often have them all sitting around all at once!Anyway ... enjoy this short clip. Sorry in advance for the poor focus pulling, and don't worry -- this was just water, not coffee.

content: Nice video, thanks!How much you paid for that model?

content: Under $3k AUD from a local supplier including GST and delivery. Considering that is less than even a FLIR E6, I am pretty happy!

content: One sold on eBay UK this month for just over £500 and it was new from a well known dealer. Prices for VGA cameras are certainly dropping. The present economic climate has certainly impacted prices on eBay.https://www.ebay.co.uk/itm/235110800592?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=p4_VkYDhQc2&sssrc=4429486&ssuid=BgpdXaaLSkK&var=&widget_ver=artemis&media=COPY

content: Wow, would have loved to have snagged that one, but alas! The going used rate for E4/E8 hasn't dropped much over the last few years? Wonder if the new wave of cheaper sharper Infiray IR sensors will change that.

content: Sadly the brand FLIR is a little like FLUKE in that the name carries a premium as it is associated with quality, whether that is deserved or not.

content: Quote from: Fraser on August 30, 2023, 04:55:41 pmCorrect me if i'm wrong, but folks buy flir/fluke for measurement purposes.I.e. thermal images cost less than correct calibrated measurements during x-time. Also yearly calibration costs $€ to keep devices correct.

content: It is true that FLIR and Fluke are often used for radiometric measurements and, in my experience, have stable calibration. Even those cameras usually have a stated tolerance of +/-2C or 2%, whichever is greater. A microbolometer based thermal camera uses the radiance ADU values from the ROIC ADC to generate temperature measurement units using a conversion curve. That conversion curve is aligned with the ROIC output values at set temperatures to create the calibration points. It would be unfair to say that FLIR and FLUKE hold the monopoly on producing thermal cameras that can make accurate temperature measurements and have long term stability. Generally speaking, the Microbolometer, ROIC and associated ADC are long lived stable components if not abused. The rest is mathsThat said, if a manufacturer skimps on the ambient temperature measurement system or calibration of the camera, errors will creep into the measurements.The recommended Annual measurement accuracy checks keep an eye on a cameras ageing for signs of performance degradation. Those annual checks do not involve calibration. Such is normally only possible at the OEM calibration centres, and at high cost. Thankfully it is rare to need such calibration unless certain camera failures occur.Fraser

content: I'm interested to see whether going forwards my customers still go for the FLIR E8 or if they will opt for the Infiray M600.We use mainly industrial Optris thermal imagers (some FLIR too) at work for our research work, and we keep an eye on things with black body calibration sources.Still, at the end of the day, for accuracy we still use contact measurements wherever possible.Just my 2 cents.

content: UPD: Damn, their description is messed up.It's384x288Btw, Decathlon in France are selling fl35r for 1.4k€https://www.decathlon.fr/p/mp/infiray-outdoor/terroculaire-infiray-fl35r-technique-laser-wifi-oled/_/R-p-e50d692b-6285-4d20-8389-4328ae3695f7Mean it could cost around 1k somewhere else.It's 640x512 12μm TIC w/ 50Hz picture.
