Which parameters are important to look for in camera specs./data-sheets if it will be used for irradiance pattern analysis from near infra-red sources. Typical spectra range of interest is from ~700nm to ~1000nm.

Typical sources would be this 850 nm IR-LED SFH 4258 , or this 905 nm laser diode SPL LL 90_3

I would illuminate a diffuse surface (e.g. grey-card) and then try to capture the image with a camera, which is max 1 to 1.5 m from the surface, for later analysis. The images would analysed in matlab or similar and I would like to have dynamic range of minimum 100 grey-scale levels.

Here is a list of the cameras that I think could be well suited.

Hamamatsu ORCA-spark Digital CMOS camera C11440-36U

WESTBORO SMART Series USB3 CMOS

For example, quantum efficiency of Basler ace camera at 900 nm is ~30% and Hamamatsu has only about 7% at 900 nm. Does this means that Hamamastu would be worse choice here or there is more things to consider ?

  • \$\begingroup\$ Obviously the change in sensitivity with wavelength will cause a "color" shift. Is that important? \$\endgroup\$ – analogsystemsrf Jan 22 at 2:25
