Knife Edge Right Angle Prism 15mm λ/4

KRPB-15-4M

Skip to the beginning of the images gallery

The knife edge prism is polished to the sharp edges of the right angle surfaces and have no chamfers on these edges.

◦With knife edge prism having no coating (KRPB) by using light in the range of 0±5.7 degrees angle of incidence to the slope surface the total reflection critical angle is obtained.

Name	Knife Edge Right Angle Prism 15mm λ/4
Weight	0.0050kgs
Standard Coatings Available	No
Guide	Contact our Sales Division with your request for custom prisms not listed on our website or in the catalog.
Remark	-
Attention	Knife-edge ridge right angle is very easily damaged so please carefully handled. The knife edge will not be able to be cleaned with lens paper. Use an air blower to remove small dust particles. A dimension measured is slightly shorter than the catalog size because it contains chamfer dimension. Dimensional tolerances are defined by the sides of the triangle with the slope and two bottom surface. KRPB (with a no coat), the reflectance of the reflection above the critical angle is nearly 100%, there is a loss of about 8% in the reflection of the input and the exit surface of the prism. Sometimes when dirt or fingerprints on the surface with no coating, total reflection will not happen anymore at the critical angle. Do not contact anything on the no coated surface.
