Setting beam height
Hold every optic in a path at one consistent deck height so components can be swapped without realignment.

NPHR Series Mounting Post
Designed for bearing heavy loads, this mounting post is compatible with the PHCR-1(A) mounting clamp, which includes a gear and rack mechanism for precise, continuous height adjustment.

Technical FAQ
Mounting Hole: Ø6.5 counter 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.
Main Body Material and Surface Treatment: Black anodized 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.
Net Weight(Kg): 1.02. 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.
