Spectral cameras & detectors
DField-VS-A1/A2/A3 Cooled Spectral CCDs
Scientific CCD readout heads for weak-signal spectroscopy across 200–1100 nm. Select A1 for UV-sensitive acquisition, A3 for near-infrared sensitivity or the deeply cooled A2 for low-light integration.
Best suited to
Spectrograph readout for Raman, fluorescence and emission measurements.
Selecting a configuration
Match active width and pixel pitch to the spectrograph focal plane. Compare cooling at the stated ambient temperature and distinguish a camera sensor array from a complete fibre spectrometer.
Measurement & configuration
- 16-bit acquisition over USB 2.0.
- Spectral binning for signal collection.
- A1/A3 trigger input and shutter-control output.
