UV-VIS-NIR Detector Based Measurements
Model : HO-SP-RE-03DM
For the precise determination angular position, particularly for the optical spectra application Holmarc has introduced a new high precision 0.0001 degree resolution spectrometer goniometer. It features low dark current linear Si-Photodiode detection unit for light measurement application. This allows users to work the spectrometer goniometer in the wavelength range of UV-VIS-NIR (320 - 1100nm). This instrument is suitable for
custom experimentation and inspection of various optical components with high precision. Open and flexible design facilitates quick modification of the instrument for custom applications.

This instrument can be used as a spectroscope for the observation and measurement of emission and absorption spectra and other application include optical measurements like precise optical angle determination of optical elements, diffraction measurements, Brewster’s angle spectroscopy, Thinfilm characterization measurements etc. When used with a prism, It can observe visible light as it is dispersed by wavelength. When used with a diffraction grating and a gas discharge tube, It can observe the emission spectrum of various gases. The wavelengths of each electron transition in the spectrum can be calculated according to the angle of deflection of the light traveling through the grating.
