High UV and NIR Sensitivity Back-Thinned TE-Cooled CCD Spectrometers: AvaSpec-HS1024x58/122
Avantes’ AvaSpec-HS1024x58/122 High Sensitivity Fiber Optic Spectrometers, part of the Sensline High Sensitivity Spectrometer family are top performing instruments featuring high quantum efficiency as well as high UV and near infrared sensitivity. These spectrometers are especially suitable for low light, fluorescence and UV applications and also have superior NIR sensitivity relative to front illuminated CCDs.
The detector pixels in the AvaSpec-HS1024x58 measure 1.392 µm high and for the AvaSpec-HS1024x122 they measure 2.928 µm high. The instrument’s optical bench design is based on a revolutionary concept with high numerical aperture and throughput. TE-cooled back-thinned CCD detectors are used as a linear array of 1024 pixels binning the vertical 58 or 122 pixels for optimal efficiency.
The spectrometers have a fiber optic entrance connector (standard SMA, other options available), toroid focusing mirrors and are available with choice of 7 different standard diffraction gratings to enable applications in the 200-1160nm range. The AvaSpec-HS1024x58/122 includes a 16 bit AD converter, and USB2.0 high speed interface. Digital IO ports enable external triggering, control of shutters, and pulsed light sources from the Avantes line of instruments.
AvaSpec-HS1024x58/122 have TE-cooled detectors with lower dark noise, better signal to noise, and enhanced sensitivity that is even 20 times more sensitive than the AvaSpec-2048x16/64. Multiple USB2 spectrometers with different detector types can be externally coupled (see section multi-channel spectrometers).
