Spectrometer - Goniometer
Model: HO-SP-RE-02
Price : $ 1,642.00

Holmarc’s Spectrometer Goniometer is designed as a versatile instrument suitable for precise determination of the optical parameters of prisms and gratings. It can also be used as a spectroscope, for qualitative examination and measurement of emission and absorption spectra. Holmarc’s well designed mechanics of the Goniometer allows maintenance-free operation over many years.

This system consists of a mercury lamp with power supply, prism with holder and transmission grating with holder. The collimator and the telescope have a focal length of 202 mm and a diameter of 32 mm. The collimator tube has an adjustable slit.
