  • Mapping area (from micro to macro area / XY travel range : 75 x 50 mm ( larger one available on request)
  • High resolution One shot raman shift measurement without any step & stitch work on CCD
(Continuous acquisition from 50 cm-1 to 4500 cm-1 with 0.5cm-1 resolution at 2400gr grating)

Aberration corrected spectrograph

  • High throughput and High resolution supported in whole spectral range
  • Minimum astigmatism over 700 nm at 2400 gr/mm grating
  • Optimized in low light application like as raman spectroscopy etc
NOST spectrograph provides narrow spectral lines of constant FWHM and intensity across the detector focal plane, whereas traditional spectrographs do not.
  • Traditional spectrograph measure Neon lamp lines that are broadened, low
  • NOST spectrograph measures the same lamp lines with around half the width and twice better intensity, giving spectra with better resolution and
  • Wavelength accuracy : Mechanical(+/- 0.15nm)/with cal(+/-0.05nm) @ 1200gr/mm grating
Mechanical(+/-0.3nm)/with cal(+/-0.2nm) @ 600gr/mm grating
  • Spectrum have no aberration at all wavelength across the entire focal plane of the
  • Excellent spectral resolution
  • Optimized in low light application like as Raman and PL spectroscopy,
Fast Mapping
  • 2500 spectrum acquired below 50 sec
  • Fast mapping function provide many advantages ( save your time for research and cost of samples)
  • It ‘s possible to use readout times as short as around 10 ms per spectrum ( depending on CCD model line)
Easy to use & less maintenance

Fully automation : motorized control by software for

  • Input laser power on sample surface
  • Adjustment Pinhole size for optimum spatial resolution
  • Autocalibration after grating
  • Laser line change
