Ultra-stable Kinematic Mirror Mounts 5KVDOM-4 are designed to minimize mount-induced wavefront distortions. In conventional mounts, the mirror is tightened by a side screw. Radial forces acting on the mirror induces parasitic wavefront distortion, such as astigmatism. 5KVDOM-4 mirror mounts use secure 3-points mirror suspension in between frontal flat spring and the back plate. Uniformly distributed axial forces eliminate wavefront distortion.

Due thermal processes on optic holding part, all metal inner tensions were removed and part makes none micro movements.

These mounts are ideal for industrial applications in different optical devices (laser cavities, optical sub-assemblies, limited space applications) because of their long-term stability.

Optics secured in double-bored hole with nylon setscrew. For any thickness optics. Fixed with 3 spots on flat spring.
For 8±0.2 mm thickness optics.

If you have optics which thickness is 20 mm, we recommend additional supporting adapter 5KVDOM-4-20/12. Custom thickness adapters available on request.

3BPVDOM Universal Base Plate
is designed for attaching Vertical Drive Optical Mounts of series 5KVDOM to optical tables or to another stages.
