Right Angle Prisms

Right angle prism is also called half cube prism or isosceles.

Besides standard Right Angle Prisms made of N-BK7 or Fused Silica, Foctek also offers custom-made Right Angle Prisms:

● Materials such as H-ZF1, H-ZF13, N-SF11, Pyrex, Sapphire and other optical glass and crystals are available.

● Size from 1.0x1.0x1.0mm to 300.0x300.0x300.0mm are available.

● Angle tolerance such as 3 min., 1min., 30sec., 10sec., 5sec., 3sec., 1sec., 0.5sec. is available.

● AR, HR, PR coating are available.
