Custom Component Description
Central Gap
Specify central
glue gap (max)
µm
7 µm is typical.
Glue thickness is about 3-5 µm

Typical face requirements are:
Face Coatings
Specify surface
treatment of all
faces
2
a – Broadband AR coating – keep the same
on all faces to minimize cost
3
b – Filters deposited on the faces – to
restrict the bandpass to the band actually
passing through the face
c – Filters cemented on the faces
- narrow pass for laser lines
- absorption to keep energy out of an
optical system
- polarizers

Can be specified in nanometers or in waves
at specific wavelengths.
1 wave on reflection surfaces and 2 waves
on faces are typical at 633 or 546 nm.

3. Applications Information
Describe in words the function of the prism. Include any explanations from the sections above, any additional
environmental (temperature, pressure, vibration, humidity, etc.), mechanical (mounting brackets, weight limits,
holes or other modifications to the glass, etc.) requirements. Attach additional documents as necessary.
