Surface blackened dispersion prism

PELLIN - BROCA prism is a special kind of Dispersion Prism.Besides dispersing properties,the Glass Prism had the property of diverging rays by  exactly 90°.By rotating the prism around it's A axis,you can select the wavelength what you require, without changing the geometry or relative positions of the input and output beams.
The dispersion prism is commonly used to separate a single required wavelength from a light beam containing multiple wavelengths, such as a particular output line from a multi-line laser due to its ability to separate beams even after they have undergone a non-linear frequency conversion. For this reason, the dispersion prism are also commonly used in optical atomic spectroscopy.

We supply other types of high precision optical glass prism,such as Wedge Prism,Right Angle Prism,Roof Prism,Dove prism,Penta Prism,pyramid prism,dispersion prism,Corner Cube Prism etc.each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.
