The diffraction angle of plane grating and holographic grating can also be measured. Various accessories and mounting options are available.
All components are made of aluminium and stainless steel to avoid corrosion. All optics used are of research quality. The slit used is of precision grade with micrometer adjustments for sub-micron sensitivity. The well designed mechanics of the Goniometer allows maintenance-free operation over many years.
The instrument can be used for inspection of various optical components in laboratories or workshops.
Open and flexible design facilitates quick modification of the instrument for custom applications. This goniometer can also be used for checking reflection & transmission ratios of thin films coated on glass substrate.
