LBTEK 2-inch low-deformation stainless steel mirror mount is used for mounting Optical Components with a mounted diameter of 50.8 mm, and comes with 2 M6×0.25 precision adjusters with knobs and locking nuts. The retaining ring + wave washer three-point fixation secures the optical component. Each mirror mount includes 1 stainless steel retaining ring + wave washer, compatible with Optical Components up to 12 mm thick. The 2 M6×0.25 precision adjusters with knobs and locking nuts provide the mount with a ±4° angular adjustment range. The knob can be turned by hand or with a hex wrench to adjust the pitch and yaw of the optical component. The optical mount has M4 countersunk mounting holes on the side. Purchasing an LBTEK stainless steel mirror mount includes ultra-thin hex socket head screws and a hex wrench.

Installation instructions: After placing the optical component, insert the wave washer, making sure that the contact points between the washer and the back of the optic are aligned with the three bosses on the mount. Place the retaining ring, turn the retaining ring until it lightly contacts the back of the optical component, then turn the retaining ring back 90° (1/4 turn). This ensures that the wave washer provides the spring force to secure the optical component, ultimately ensuring that the surface figure of the optical component in the mount is below 0.1λ.
Note: These mounts are designed for 50.8 mm optical components with a tolerance of +0/-0.13 mm. For low surface figure applications, the 1 plastic-tip screw on the three bosses must be completely loosened and must not contact the optical component. For applications without low surface figure requirements, a torque wrench can be used to tighten the optical component at 2 cN·m torque for longer-term stability.
