Omni-λ series Monochromator / Spectrograph

/ Spectrometers

Omni-λ series grating spectrographs / Monochromator

The rugged high performance Omni-λ Series is an ideal choice for either single or multichannel detector use in many applications that require medium to high spectroscopic resolution with excellent stray light performance such as fluorescence, Raman, absorption, transmission or source characterization measurements.

  • Manual micrometer adjustable slits for precision control of incoming light
  • Motorized slit and fixed slit is option
  • More than 100 gratings for the best spectral range, throughput and dispersion to meet your application DSP controlled stepping motor scanning system provides superior precision and repeataility of wavelength positioning
  • Optional internal shutter or six-position filter Wheel for experiments requiring background removal or signal attenuation
  • Installation and set-up through USB 2.0 computer interfaces
  • Stand-alone Omni Series monochromator control software for basic scanning and calibration
