Edmund Optics Introduces UV Fused Silica Penta Prism

Thermally stable prisms provide excellent UV transmission

October 16, 2007, Barrington, N.J. Edmund Optics® introduces a new line of TECHSPEC(TM) UV Fused Silica Penta Prisms. These five-sided prisms reflect light rays through a 90° angle by two reflections without inverting or reverting the image. They serve as a valuable tool to shorten the optical path length of an instrument while maintaining the image orientation. This is essential when space is at a premium.

The new prisms are made from UV grade fused silica, which has a coefficient of thermal expansion of just 0.5 µ/°C. They offer excellent transmission throughout the UV, visible and NIR spectral ranges. These features make these prisms ideal for applications where the temperature cannot be controlled, including surveying, long-distance alignment and range finding instrumentation.

A variety of coating options enhance overall efficiency; uncoated or reflecting surfaces can be aluminized, overcoated with inconel and black paint. The entrance and exit faces are available uncoated or UV-AR coated. The thermally stable penta prisms provide improved surface accuracy and surface quality compared to BK7 prisms. These prisms are manufactured to a surface quality of 20-10, a surface accuracy of 1/10 and a dimension tolerance of +0.10 mm.
