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.
