Mirror Mounts

Optosigma Mirror Mounts are optomechanical fixtures that hold and position mirrors with controlled angular adjustment. They are available in kinematic (adjustable) and fixed configurations, covering mirror diameters from 12.7 mm (0.5 inch) to 76.2 mm (3 inch) and larger.

Kinematic mirror mounts:
– Two-axis (pitch and yaw) angular adjustment via fine-thread screws or differential actuators
– Spring-loaded or magnetic kinematic couplings for repeatable repositioning
– Locking screws to fix position after alignment
– Resolution: typically 10-30 arcsec per graduation depending on model

Fixed mirror holders:
– Fixed-angle (45-degree) holders for beam-steering at defined angles
– Zero-degree (normal-incidence) holders for retroreflector arrangements
– Useful where adjustment is set once and locked permanently

Material and construction:
– Aluminum body (anodized); stainless steel screws; some models with Invar inserts for invar inserts for thermal stability
– Magnetic kinematic mounts: allows quick mirror swap with repeatable return positioning

Compatibility:
– Fits standard Optosigma and metric/imperial mounting post systems (M6 and 1/4-20 threads)
– Post-mountable or breadboard-mountable configurations

NewRoad provides Optosigma mirror mounts in Israel for laser laboratory setups, interferometers, and OEM instrument builders.
