Character

l The Nonsymmetrical optical system, designed to use the Czerny-Turner system, produces symmetrical, coma corrected spectral lines and high resolution.

l The Stray light corrected design.

l The standard entrance is designed to easily accept our corporation’s light sources, or fiber with available fiber interface.

l Worm-drive system, Multi-grating turret, changing gratings automaiticaly by stepping motors

l The automatic equipment utilizes stepping motor scanning system with microprocessor control or computer control.

l Nitrogen connector is available for UV and NIR testing.

l Fine material selection , standard craft, excellent manufacture, good performance and uniformity.

l Widely applies in teaching, scientific research, luminosity, chromaticity measurement, the coating machine, air pollutionsurveillance and so on.

l Optics chamber and mechanical drive chamber are separated, reduces stray light and pollution to optical components
