Oriel Corporation 77250 1/8 m Hand Operated Monochromator is a laboratory optical instrument designed for wavelength selection in spectroscopy, optical characterization, photonics research, and scientific testing. It is widely used in research laboratories, universities, materials science, and optical measurement systems where precise isolation of specific wavelengths is required.

The monochromator operates by directing incoming light onto an interchangeable diffraction grating, which separates the light into its individual wavelengths. A manually adjustable wavelength mechanism allows the user to select a narrow spectral band that exits through the output slit for use with detectors, optical sensors, lasers, or other laboratory instruments. Its modular design supports different gratings and slit configurations, making it suitable for a wide range of spectroscopy applications.

CONDITION: This unit is untested and sold as-is. Cosmetic wear may be present from previous use. Gratings, slit assemblies, detectors, power supplies, cables, manuals, and original packaging are included only if shown in the listing photos.
