Custom optical prisms
A prism can be used to turn light at a particular Angle. A prism can not only deflect light, it can also adjust the direction of the image. The design of a prism will determine how it interacts with light. When light enters a prism, it is reflected on a single or multiple surface before coming out, or it is refracted as it passes through the substrate. For example, when light is incident to the rectangular prism, the light will be reflected in the surface of a rectangular prism, and then to a 90 ° turn. However, when light enters a wedge prism, the change in substrate thickness causes the light to deflect through refraction.
DG optoelectronics offers a variety of designs, substrates or coated prisms.Prism design includes rectangular, armisian ridge, pentagonal, Schmitt, wedge, deformed, equilateral, dowell, or rhombic prism.In addition, we also provide a pyramid prism reflector, or homogenized columnar homogenizer. While the optional coating including MgF2, UV – VIS, UV – AR, VIS 0 °, VIS NIR or multiple laser line option.
