The role of discount penta prism

The role of discount penta prism

2022-07-28 08:32
The discount penta prism is a reflective device used for framing of the SLR camera. Its function is to correct the upside-down image on the focusing screen, so that the image seen in the framing is exactly the same as the scene directly seen, so that the operator can correctly framing and focus. When the shutter is opened, the mirror is turned up to let out the light path, and the discount penta prism is opaque.

How discount dispersing prism works

Discount dispersing prism is a glass block in shape of pentahedron with three optically active surfaces. These prisms operate in transmitted light and are commonly used to diverge light in broad range of optical systems. The direction of light exiting the prism depends on wavelength, a feature which allows the prism to separate incident beam into its component wavelengths.
