C11708MA spectrometer
Hamamatsu Photonics has introduced an ultra-compact spectrometer — built using MOEMs technology — for use in portable and handheld devices.
Measuring 27.6 x 13 x 16.8mm and weighing just 9g, the C11708MA uses an aberration-corrected concave grating with a very short focal length and a blazed grating profile to ensure high diffraction efficiency.
The grating is replicated on top of a convex glass lens using nano-print technology.
Directly opposite the grating is a dedicated CMOS silicon image sensor with an on-chip slit. This 75 x 750µm slit is formed into the CMOS chip using MEMS technology.
