An IR camera ignores any visible light by the lens/filter just mid IR is passing to the sensor, so if the camera is rated like 350 or 550°C it can handle that temperature on the sensor
That is good news. However, I wonder if the IR camera will ever have any chance to pick up a 0.15x0.15mm spot. If there is no choice, I guess I just need to burn holes and then turn down output by some percentage.
Depends on resolution optic and focal distance, usually mor than just the laser spot will be at a relative hot temperature
My Fluke can focus down to 15cm and has 3.39mrad at 160x120 pixels, so on 15cm one pixel is 0.5mm with 22.5 °H x 31 °V FOV
A 640x480 with 15cm and same FOV has a resolution of 0.125mm
320x240 0.25mm
I never really thought about focus all this time. My thermal camera does not have a focus option! It is high res 320x240 without any focus (HT-19 thermal camera). Is it possible to get a lens to go in front to get a good macro focus?
Random late night CAD hahaha
With resin 3d printers, extreme accuracy parts are quite easy to achieve now.
Laser can be focused by twisting lens. Collar can be focused with the multi axis mounting. Mirrors can be adjusted.
A collar is such a pain to use!!!
