Where it fits
The sMAX04BM is worth considering for fluorescence imaging, spectral analysis, gene sequencing and semiconductor inspection where cooling and broad spectral response are important.
What to check before ordering
Confirm sensitivity at your exact wavelength, exposure requirements, optics, field of view and software workflow. Its rolling shutter should also be assessed if your sample or illumination changes during an exposure.
