Description
Tuniu provides an achromatic variable beam splitter with three working wavelengths: 420-680 nm, 700-1000 nm, and 1100-1600 nm. It is composed of a broadband polarizing beam splitter cube and a quartz achromatic half wave plate. The half wave plate changes the polarization direction of the incoming polarized light, and when combined with the polarizing beam splitter cube, it can achieve continuous changes in the transmitted polarized light intensity. It can also be used as a beam splitter that meets specific beam splitting requirements.
The achromatic variable beam splitter provided by Tuniu has the characteristics of wide adjustable range and easy module installation and use, which is suitable for multiple use scenarios such as holographic technology and interferometric measurement.
