The compact grating spectrometer CGS UV-NIR is a class of its own. Extremely compact, a rugged design, and with various detector (CCD or PDA) options allow users to measure with maximum quality and optimal spectral efficiency.

The CGS utilizes an aberration corrected imaging grating, a SMA connector as optical input and a CCD or Si Photodiode array (PDA) detector.

The uncooled, back thinned CCD detector captures clear, bright images and ensures high sensitivity. The PDA has extremely low noise and high S/N, even at low light levels. The core component of the spectrometer is a blazed, flat-field grating for light dispersion and imaging. The overall configuration results in a spectral pixel pitch of 0.4 nm/pixel (CCD) and 0.7 nm/pixel (PDA) with spectral resolution of around 2 nm (depending on slit size) according to Rayleigh criterion. The optical interface is an SMA fiber connector with fixed entrance slits (various widths are available) to allow precise alignment of fibers. All optical components are attached to an Aluminum housing.

The spectrometer modules\' compact body and thermally stable design make them ideal for industrial applications. Low thermal expansion and minimum stray light guarantee reliable measurement results, even in rough environments. The CGS spectrometer family completes the product lines of the MMS, MCS, and PGS spectrometer modules.

The flexible design of the Carl Zeiss spectrometer modules suits many applications. Spectrometers made by Zeiss can be classified according to he measurement principles, the field of use, or material to be analyzed. However, the most important benefits of the CGS are the compact body, reasonable price and insensitivity to external influences which allow direct process integration.
