Omni-λ Monochromators and Spectrographs

Details&Spec

Details

■ 200mm, 320 mm,500 mm,750 mm focal length

■ Our rugged Czerny-Turner spectrographs come pre-aligned and pre-calibrated for ease of operation.

■ Interchangeable triple grating turret Different wavelength ranges and resolutions, Provide a simple, accurate and convenient way for the user to change gratings within the spectrograph unit

■ These instruments can be integrated with single point detectors, InGaAs cameras and CCDs to offer a versatile, most sensitive modular solution for different applications ;

■ Accessories including filter wheels, fiber adapters, shutters, motorized slits, sample chambers etc.

■ Software can complete data acquisition for detectors including single point detectors and CCD.

■ Labview driver for programming to operate Omni-λ Series spectrographs and monochromators.
