Hamamatsu Photonics has introduced the new C11708MA; a unique, ultra-compact spectrometer built using MOEMS technology.
The C11708MA is a thumb-sized device, measuring only 27.6 x 13 x 16.8 mm, developed for use in portable and hand-held devices, where a standard mini-spectrometer would be too large and consume too much power.
Not only small, but the C11708MA is also light, weighing only 9 grams.
To achieve such a small size required the combination of Hamamatsu’s MEMS and image sensor technologies.
The new device uses an aberration-corrected concave grating with a very short focal length, and a blazed grating profile for high diffraction efficiency.
The grating is replicated onto the top of a convex glass lens using nano-print technology.
Directly opposite the grating is placed a dedicated CMOS silicon image sensor with an on-chip slit. This 75 µm x 750 µm slit is formed into the CMOS chip using MEMS technology.
Through the use of these novel techniques, the C11708MA can offer a spectral resolution of 20 nm in the wavelength range of 640 nm to 1050 nm, making it ideal for a range of applications requiring a miniaturized infrared spectrometer head.
To aid initial evaluation, a dedicated driver board, the C11351, with USB 2.0 connectivity and 16 bit A/D resolution is readily available.
This is Hamamatsu working at the forefront of today’s MOEMS technologies, to bring unique and exciting products to an ever demanding market.
