Brand: Outai Optics

Series: Prism series

Type: Optical conduit

Specification: Material: quartz glass, plated medium film, metal film glass

Size: 10*10*10mm

Working band: 400 ~ 700nm

Efficiency: > 98%

Coating: The surface of the hollow light tube is plated with anti-reflection film

Finish: 40-20

Transmitted wavefront error: < λ/4@633nm

Features: The uniform rod is hollow and solid, the hollow inner layer is generally plated with high reverse film, and the solid one is generally quartz glass or K9 glass.

It can be homogenized into the beam spot. It is an important device in projection display.

The principle of uniform light: the light is reflected several times in the light rod, each reflection will form a virtual light source image, and multiple reflections form a two-dimensional virtual light source matrix, so that the light is more uniform. With the increase of the length of the rod, the uniformity of the rod presents an oscillating rise. After reaching a certain degree, the continuous increase of the length does not significantly improve the uniformity, but reduces the brightness.
