PoliSpectra® 135

Multichannel Spectrometer and Hyperspectral Line Imager

HORIBA has developed a high-performance rugged spectroscopy platform that is factory-configurable for use in a multichannel or hyperspectral imaging system. This system can be configured with our Sylent® 2D sCMOS camera, low-cost cameras, or even customer-supplied sensors. In hyperspectral imaging applications, this system can be used as a line-scanning instrument (push-broom) that collects full spectral data simultaneously across the input slit height.


  • Multichannel (M135) vs. lens-based or bare slit (H135)
  • Two gratings to choose from: UV-NIR or VIS-NIR
  • Default sensors are the Sylent sCMOS cameras (cooled to -25° C or uncooled), or any customer preferred sensor

For OEM Industrial Applications

  • Optical Emission Spectroscopy (OES)
  • Fluorescence
  • Hyperspectral Line Imaging
  • Semiconductor Inspection and Metrology
  • Semiconductor Process Monitoring
  • Aerial Reconnaissance

Segmento: Scientific
Fabricante: HORIBA Scientific
  • Up to 96 fiber channels with simultaneous readout (factory configurable)
  • Ultraviolet hyperspectral line imaging (180-1050 nm)
  • High throughput combined with low stray light
  • 2D scientific CMOS with high quantum efficiency and low noise


Spectral Line Width Graphs

The wavelength resolution specification establishes the maximum width (FWHM) of all spectral lines on all channels. This is a more stringent requirement than using the mean as the specification.


A lens-based hyperspectral H135’s resolution is dependent on the grating, slit, and f/# of the lens used.

1 Max spectral line width (FWHM) for all peaks in the image.
2 Versus a sensor row.
3 The Crosstalk % can be further reduced with more dead space between channels. Measured on one channel (off), with all other channels illuminated. See Cross Talk Calculation figure on pages following.
4 Stray light measured using a BP filter: Baseline light level (outside the band) divided by the BP peak (unsaturated).
5 Smile is eliminated by using channel calibration coefficients.
