UV-VIS-NIR Spectrometer

Horiba’s OEM division, a major supplier of OES solutions, has developed a high end OES Spectrometer with a proprietary optical configuration for broad coverage (185-1050 nm) and high resolution. The OES-Star is available with a selection of three UV-VIS-NIR Back-Illuminated (B.I.) sensors, one TE-Cooled and two uncooled CCD detectors. This unique OES system features an optical design that provides a high peak symmetry across a very broad spectral range combined with high spectral resolution better than 1 nm, at an unmatched aperture of F/2.3.

For OEM Industrial Applications

  • Optical Emission Spectrometry
  • Reflectometry
  • Process and Quality Control
  • Examples:

  • Optical emission spectrometry (OES)
  • Unmatched long term stability and excellent wavelength accuracy
  • USB2 Ethernet and EtherCAT interface
  • High spectral resolution combined with high throughput
  • Broad wavelength coverage from UV to NIR 
  • Multiple B.I. CCD options cooled/uncooled with high dynamic range 
  • CMOS sensor option with electronic shutter and ultra high spectral rate


Flat resolution and dispersion across the entire spectral range (185 -1050 nm) combined with excellent peak symmetry

This OES-Star is featuring a tall CCD with built in round-to-line (RTL) fiber converter to maximize light collection and therefore the system throughput. Input fiber with a core of 1 mm or smaller can be used. However to take advantage of the tall detector and RTL, larger core fibers are recommended.


Built-in round-to-line (RTL) converter boosts throughput when combined with a large core diameter fiber and our tall CCD (S13241-1108S)
