Prism

Prisms are blocks of optical material with flat polished sides arranged at precisely controlled angles to each other, which deflect, deviate and rotate beams of light as well as dispersing their wavelengths.

We can manufacture many types of prism, each having a particular geometry to achieve the reflections necessary to perform a specific imaging task. Reflecting prisms may invert, rotate, deviate or displace a beam. Dispersing prisms produce spectral separation for spectroscopic applications or for tuning a laser output.

OP-Unite provides Right Angle prism, Penta Prism, Corner Cube and custom shape prism with the material of all kinds of Chinese Optical Glass, B270, BK7, UV Fused Silica, CaF2, MgF2, Silicon, Germanium and etc. Reflecting and anti-reflection coatings on working surfaces can be put if necessary; more details please refer to our coatings chapter.

Most of our prisms are widely used for laser and commercial applications; hereby we briefly describe six applications of prisms to illustrate the versatility of this optics:
¡ñPrism spectrometersBeam turning
¡ñBeam steering
¡ñLaser tuning
¡ñEvanescent wave coupling
¡ñPrisms as beam expanders
