PoliSpectra® VS70 Dual & Quad
DUAL & QUAD CCD Mini-Spectrometer
Specifications:
Spectral coverage | UV-VIS (200–860 nm), 250 nm optimized grating, built-in order-sorting filter (DUAL only) |
Numerical aperture | f/2.3 |
Stray light rejection & Cross-talk | Stray light: 0.02 (max) for UV-VIS configuration with 300 µm tall CCD, measured at 700 nm (measured with broad bandpass 510 nm filter, 75 µm slit-width) Cross-talk: 0.1% (max) |
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) 200-400-600 µm dia., 1.5 m long fiber-optic (for 1 mm tall CCD, prefer 600-800 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. |

A/D converter | 16 bit, 2-3 MHz (pixel rate) |
Typical dark current | 50 e-/pixel/sec at 20°C (room temp.) |
Typical readout noise | 30-35 e– RMS |
Readout speed | (1.3) ms; 890 (760) spectra/s with 0 ms exposure time with respectively 300 µm (1000 µm) CCD height (with fast CCD option) |
