This VS7000-CCD-HD system for industrial applications uses a modified VS70 optical engine optimized for UV - VIS

Spectral coverageUV-VIS (200–860 nm), 250 nm optimized grating, built-in order-sorting filter
VIS (380–750 nm), VIS-blazed grating, built-in long-pass filter
UV-NIR (200–1050 nm), dual-blaze grating, built-in order-sorting filter
Numerical aperturef/2.8
Stray light rejection
Typical (Maximum)
0.01% (0.02%) for UV-VIS configuration with 300 µm tall CCD, measured at 700 nm
(measured with broad bandpass 510 nm filter, 75 µm slit-width)
>2.4 AU linear range (5% variation) with caffeine 273 nm absorption peak in 10 mm cuvette and D2 lamp.
CCD detector
Typical QE
Back-illuminated CCD with low etaloning in NIR
65% peak QE in UV
Detector height
Fiber-optic option
300 µm CCD height standard (1000 µm optional)
600 µm dia., 1.5 m long fiber-optic (for 1 mm tall CCD, prefer 800–1000 µm dia.)
Thermoelectric stabilization

None. Dark current and CCD-pattern noise must be subtracted. User must switch off light source or install
manual shutter in optical path. QE shifts slightly with temperature.
