Spectra UV-VIS-NIR High Throughput

DUAL Grating f/3.5 Monochromator

Model : HO-HTDG 175F2

HOLMARC’s 175F2 monochromator having 175 mm focal length is an out-of-plane version of Ebert-Fastie monochromator. It is designed with large optics for high light throughput and f / 3.5 aperture, optimized to provide excellent stray light rejection while minimizing aberrations. The optical configuration is designed to ensure high resolution and maximum throughput.

175F2 has computer controlled, motorized turret for automatic grating and wavelength selection. It offers 0.2 nm resolution in UV-VIS region with 1200 lines / mm grating and 0.25 nm in IR region with 600 lines / mm ruled grating, covering wavelength range of 250 nm to 1900 nm. Monochromator includes adjustable micrometer controlled input and output slit.
