Depolarized Splitting Prism
PRODUCT CATEGORIES
INOUIRY
- It is different from the energy spectroscopic type. Without changing the polarization state of the incident light, the depolarized splitting prism divides the incident light into transmitted beam and reflected beam according to the calibrated splitting ratio. It should be noted that the depolarizing beam splitting prism adopts metal induced beam splitting film, so it has a certain absorption of incident light (usually < 10%), which should be paid attention to when the laser power is large.
