Burleigh SG201 2″ Gimbal Mount with Lens Mount

Description

Burleigh SG201 2″ Gimbal Mount with Lens Mount.

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 include the optic carrier, but do NOT include the optional angle support bracket.

The micrometer spindles are the earlier versions without the large diameter plastic rings. Each axis has internal springs to keep the gimbal plates in contact with the micrometer spindles, and in addition, a spring-loaded plunger for extra rigid settings. 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.

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
Overall depth with micrometers � 4 inches
Minimum / Maximum mirror thickness � 0.25 / 0.60 inches.

Listing includes gimbal mount and the 2 inch optic cell with retaining ring. Condition of everything is excellent. For the most part, these mounts are the earlier versions using heavy cast iron or steel components (later mounts used a much lighter aluminum alloy).
