- High-Sensitivity Spectrometer
Jan 2011Avantes BVRequest Info
Avantes BV has unveiled the AvaSpec Sens-Line high-sensitivity
spectrometers that are designed for applications such as fluorescence spectroscopy
and low-light-level detection. Features include high quantum efficiency, back-thinned
CCD detectors and a proprietary optical bench. The ULS2048x16-USB2 model features
high quantum efficiency for measurements in the UV to NIR range (200 to 1160 nm).
The effective detector height with 16 pixels of 14 μm is 224 μm, and the
pixels are vertically binned. The ULS2048x64-USB2 has 64 pixels measuring 14 μm,
vertically binned to an effective detector height of 900 μm, and its sensitivity
is four times higher. It supports 1.75-ms integration times, and its specifications
related to dark noise, etaloning, antiblooming and dynamic range are similar to
those of the other model.
