Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Orient a prism about the axes that matter for deviation, dispersion and polarisation.
Set the rotational orientation of a cylindrical lens so its power axis lands where intended.
Hold a folding prism steady where a mirror pair would introduce extra alignment freedom.
System integration
Use these checks to connect OMHS-PM60 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Mounting Hole: M6,φ8 sink hole. 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.
Adjustment Angle Range (°): ±3 · Resolution: angular adjustment per revolution(°): ≈0.25. Adjuster pitch sets the sensitivity you can actually work at. Confirm whether the stated figure is a total range or a per-revolution increment, and whether the mechanism is locked after adjustment.
Main Body Material and Treatment: Aluminium alloy, surface treated by black anodic oxidation.. 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.
Max Load height (mm): 60 · Net Weight (g): 240. Use the stated geometry and mass to fix beam height, clearance and the load carried by whatever this part is bolted to. These are the numbers that decide whether adjacent components physically collide.
Model selection
Compare OMHS-PM60 with the closest available models in the OMHS-PM series Prism Kinematic Mount family. Confirm option-dependent values on the final configuration before ordering.

Before you specify
Engineering context for choosing this class of component, with the tradeoffs worked through on real specifications.
Opto-mechanicsVibration, thermal drift and mechanical integration are one problem. Budget the motion at the sample, then specify the table, the isolation, the mounts and the beam height that budget asks for.
