Compact VGM Series Vertical-Drive Gimbal Mounts simplify true gimbal adjustment of optics up to 2 in. in diameter without sacrificing stable, high-resolution positioning performance. With both drives accessible from the same side, these mounts are ideal for applications where adjustments must be performed without obstructing the beam path, such as laser-cavity mirrors, output couplers and beamsplitters. By extending the drives through the top or side of safety enclosures, adjustments can be made without enclosure removal.

Optics are positioned so that their front surface is at the gimbal plane for uncompromised adjustability. Precision manufacturing techniques result in isolated, independent axis adjustments with minimum cross-talk and drift for demanding intra-cavity applications.

The VGM mirror mounts are offered with a choice of two different standard drives. The VGM-1AJS and VGM-2AJS feature precision 100 tpi drives. The VGM-1BD and VGM-2BD feature differential micrometers with resolution nearly ten times greater than standard vernier micrometers. For automated mirror alignment, the CMA or LTA Motorized Actuators are recommended. These offer incremental motions as small as 0.02 µm–0.1 µm.

Each gimbal mount comes with a universal base plate that mounts to English or metric hole patterns. Use RH Series Riser Blocks to mount these components at fixed optical axis heights with excellent stability.
