Rhombic Prism


Products Description:


Prisms are optical components having particular geometry to perform reflections or transmissions for imaging perpose, They deflect, deviate and rotate beams of light as well as disperse their wavelengths. Focus Technology offers various of high precision prisms, select a suitable prism is important for your applications.

Rhomboid prisms are widely used to displace a laser beam without changing its direction. In imaging applications, rhomboid prisms will displace the optical axis without inverting the image.
