Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Cavity and interferometer alignment
Hold pointing where a few microradians of drift is visible directly in the measurement.
Repeatable optic exchange
Kinematic seating returns an optic to the same orientation after it has been removed.
System integration
Integration and compatibility
Use these checks to connect OMMB80-2BT to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optic it accepts
- Optic Size(mm): φ80 · Clear Aperture(mm): 75
- Check diameter and thickness together. A holder that accepts the diameter can still fail to retain an optic that is thinner than its minimum, and clear aperture is normally smaller than the optic the mount holds.
- Mounting interface
- Mounting Hole(mm): φ7.5 counter bore, 2*φ11counter bore
- Match the thread standard and hole pitch before ordering. Metric and imperial hardware interchange only through an adapter, and a thread that is nominally similar is not necessarily the same pitch.
- Material and finish
- Material: aluminium alloy
- Aluminium moves about 23 ppm per kelvin and stainless about 16. In a path where thermal drift is already budgeted, the material of the mount belongs in that budget rather than in the appearance of the part.
Technical FAQ
Integration questions for OMMB80-2BT
