Type:
Pellin-Broca
-
Material:
BK7, fused silica
Extremely small loss for p-polarized beam
Separated by wavelength light is conveniently turned by 90? angle with minimum deviation
UVFS prisms provide 1.26? separation between 532 and 1064 nm
In a Pellin-Broca prism, an ordinary dispersing prism is split in half along the bisector of the apex angle. Using a right angle prism, the two halves are joined to create a dispersing prism with an internal right angle bend obtained by total internal reflection. The entrance beam is deviated at 90? angle to its initial direction
