Spectrometers - VS7000+

OEM CCD Mini-Spectrometers

HORIBA Scientific’s VS-7000+ is the latest evolution of our low-cost, high-performance family of CCD mini-spectrometers.

This fiber spectrometer provide spectral coverage for UV-VIS (200–860 nm), VIS (380–750 nm), and UV-NIR (200–1050 nm).

And, this miniature spectrometer offers high throughput (f/2.8 and tall CCD), a new high dynamic range CCD (7000:1), and ultra-low stray-light rejection thanks to the concave grating design..

The VS-7000+ is the ideal grating spectrometer for OEM industrial low-light applications such as fluorescence, emission, absorbance, and reflectance. It outperforms current mini-spectrometers based on front-illuminated Sony or Toshiba CCDs, or low-cost back-illuminated CCDs.

Numerical apertureF/2.8
Stray light rejection
Typical (Maximum)
  • 0.04% (0.08%) for UV-VIS configuration with 300 μm tall CCD.
    (measured with broad bandpass 510nm filter, 75μm slit-width)
  • >2.4 AU linear range (5% variation) with caffeine 273nm absorption peak in 10mm    cuvette    and D lamp.
CCD Detector & Typical Q.E.Back-illuminated linear CCD with low etaloning in NIR – 65% Peak QE in the UV
CCD Detector height & Fiber-optic option300 μm standard CCD height ( 1000 μm CCD height is available as an option)
600 μm diameter, 1.5m long fiber-optic (Fiber is not an option; for the 1 mm tall CCD, prefer an 800-1000 μm diameter fiber)
Thermoelectric stabilizationNone.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.
