CG216 Series

Perfect Choice for Spectral Applications
UV enhancing coating for UV Range Spectrometer

The CG216 Series spectrometers are cost-effective high-performance CCD based instruments designed for use with a PC. The standard sensor arrays used in the spectrometer is Toshiba TCD1304DG B/W board-level line CCD camera, based on a single-line, 3648-pixel CCD chip. The array driver electronics has been developed by Holmarc and designed for highly sensitive yet stable operation. More pixel numbers in the sensor makes the CG216 Series spectrometers more suitable for the applications requiring high resolution. Thanks to high sensitivity of the CCD, the spectrometer can be used for applications with low light signals as well. It can accept light directly through its built-in slit or via optical fiber. UV spectrometer uses windowless CCD to increase the UV sensitivity down to 200nm. It helps the signal sensitivity below 380nm get improved ~20 - 50% more in general.

-30 Degree Cooled CCD

Peltier cooling device integrated intospectrometer sensor can reduce the temperature of the CCD chip by -30°C against ambient, improving the dark baseline level by a significant factor of 2 - 3. It makes this instrument ideally suitable for measuring low light applications like fluorescence.
