Stray light rejection
Typical (Maximum)

0.1% (0.2%)
(measured with bandpass filter 780BP10)

CCD Detector & Typical Q.E.

Back-illuminated CCD with low etaloning in NIR
55% peak QE at 850nm(VIS optimized)

Detector height
Fiber-optic option

300μm CCD height standard (1000μm optional)
200 or 300μm dia.,1m long fiber optic (for 1mm tall CCD, RTS bundle is offered)

Thermoelectric stabilization

None. Dark current and CCD-pattern noise must be subtracted. User must shutter in optical path. QE shifts slightly with temperature.
