Burleigh 2 inch Gimbal Mount SG201

Description

Burleigh 2-inch Gimbal Mount with Support 2 in.

This is a Burleigh gimbal mount for optics or mirrors of 2 inches diameter. It is a true gimbal � both the azimuth and elevation axes are co-planar with the front surface of the mirror cell. The mounts are exquisitely made from three basic castings � two for each of the gimbal planes and one for the supporting plate. There are three basic subassemblies to the mounts. The gimbal mount with the micrometer spindles; the removable optic carrier mount; and the angle support plate. These mounts all come complete with all three components.

The micrometer spindles have large diameter plastic rings attached to the spindle drum to make it easier to accomplish very precise adjustments. Each axis has internal springs to keep the gimbal plates in contact with the micrometer spindles, and in addition, a spring-loaded plunger to augment stability. The position of the plunger can easily be changed so it will be effective in the range of motion required.

The second assembly is the optic cell. This entire assembly is held in place by a large knurled collar from the back. It is possible to remove the cell from the gimbal mount in order to install the optic of interest. The cell is designed so the reference plane of the mirror sits precisely in the gimbal plane. The front of the cell is chamfered so almost the entire mirror surface may be used when the incident light angle is less than or equal to 45 degrees. The cell will accept mirrors between 0.25 and 0.50 inches in thickness without additional spacers (thinner mirrors require spacer rings). The optic carrier includes a threaded retaining ring for the mirror.

The last component is a right-angle bracket for attaching the gimbal mount to a table. The gimbal mounting support plate attaches to the bracket with four Allen cap screws.

Dimensions:

Gimbal support plate � 4 inches wide, 4.75 inches tall (0.500 inches thick)
Optic axis height = 2 inches
Range of motion (azimuth and elevation) � approximately plus or minus 2 degrees
Modified Starrett 263 micrometers with large thimble rings
Overall depth with micrometers � 4 inches
Minimum / Maximum mirror thickness � 0.25 / 0.60 inches.

The base plate adapter (right-angle bracket) raises the optic axis height to 2.375 inches. Overall baseplate dimensions are 4 by 4 inches. The reference plane lies approximately 0.875 inches from the front of the base plate.

Listing includes gimbal mount, 2 inch optic cell with retainer, and support bracket. Condition of everything is excellent. For the most part, these mounts are the later versions using a lighter aluminum alloy for the castings instead of steel, however there are some of both types, however.
