VGM Series Vertical-Drive Gimbal Optical Mounts

Product catalog summary

Overview: The document provides technical specifications and ordering information for the VGM Series Vertical-Drive Gimbal Optical Mounts and the 600A Series Precision Kinematic Optical Mounts. These mounts are designed for precise optical adjustments in various applications.

VGM Series Vertical-Drive Gimbal Optical Mounts:

Specifications: Available in two models, VGM-1 and VGM-2, supporting optics of 25.4 mm and 50.8 mm diameter respectively. They offer a clear aperture of 21 mm and 46 mm, with maximum mirror thicknesses of 8 mm and 13 mm.
Features: Compact design with top or side-mounted micrometers for unobstructed adjustments. They provide isolated, independent axis adjustments with minimal cross-talk and drift.
Ordering Information: Models include various adjustment screws and micrometers, with options for actuators and adaptors for different optic sizes.

600A Series Precision Kinematic Optical Mounts:

Specifications: Designed for 2 in. and 4 in. diameter optics, these mounts offer a detachable baseplate for conversion to left-handed versions and compatibility with motorized actuators.
Features: Include hardened inserts for durability, and the ability to replace the pivot bearing with a third actuator for pure translation without tilt.
Ordering Information: Includes adaptors for various optic sizes and compatibility with both metric and English tables.

Additional Information: The document references related products such as Ultrafast Laser High Reflecting Pump Mirrors and Broadband Dielectric Beamsplitters, and provides contact information for further inquiries.

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 intracavity applications.
