Other: most of the work is in decapping, not actual imaging. If you happen to already have a bare, clean die and would be satisfied with a quick / lower quality scan, feel free to send me a few dies. This also can work out well since most of the NRE cost is in the microscope, not the decapping supplies. | Other: most of the work is in decapping, not actual imaging.

+ | mit20x vs mit20x2: | ||
+ | * mit20x: BH2 microscope, MU800 camera, 0.5x relay lens, Mitutoyo M Plan Apo lens | ||
+ | * mit20x2: BH2 microscope, USB3 camera, 0.75x relay lens?, Mitutoyo M Plan Apo lens | ||
+ | * Select medium resolution 2736 x 1824 | ||
+ | * 20x | ||
+ | * 0.42 @ 800 nm => 952 nm R objective resolution | ||
+ | * 0.42 @ 532 nm => 633 nm G objective resolution | ||
+ | * 0.42 @ 400 nm => 476 nm B objective resolution | ||
+ | * About 820 um wide field of view | ||
+ | * 820 / 2736 = 300 nm / pix raw | ||
+ | * Cut image by half to sample RGB correctly => 600 nm / pix | ||
+ | * 820 / 2736 / 0.5 = 599 nm / pix ultimate image resolution | ||
+ | * vc60x => 1.4 NA | ||
+ | * 1.4 @ 400 nm => 143 nm objective resolution | ||
+ | * About 820 / (60/20) => 273 um FOV | ||
+ | * 273 um / 2736 pix / 0.5 pix/pix => 200 nm / pix ultimate image resolution | ||
+ | * Conclusion: possibly losing slight resolution in blue, but probably good enough | ||
