Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Hold a lens without inducing the birefringence or figure error that clamping pressure causes.
Position a lens along the axis to place image and Fourier planes where the design requires.
Bring the optical axis of the lens onto the axis of the beam rather than the mechanics.
System integration
Use these checks to connect OMLS50-1 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Optic Size (mm): φ5~φ50 · Max Clear Aperture A (mm): φ46. 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 Hole: M6. 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.
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.
Net Weight (g): 85. 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.

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.
