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 an optional angle support plate. These mounts do NOT include the optic carrier or 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.

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 (optic cell not included)

Listing includes ONLY the gimbal mount. 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).

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.

This item is a Klinger (also known as Micro-Controle, and now manufactured by Newport) SL type Gimbal optic mount. The SL gimbals are characterized by massive steel construction with two mounting flats for orthogonal positioning of the tilting axes so the controls are on the right or left side of the beam path. The two planes of tilt perfectly intersect the plane of the optic (often a mirror) so adjusting azimuth or elevation results in the reflection point always being stationary on the optic axis. The elements are held in place by a spring-loaded ring. There are three small bearing points to precisely locate the optic in the main yoke, and another three within the spring-loaded clamping ring. The securing screws are not quite symmetrically placed to aid in removal of elements through the slightly larger opening.

This particular gimbal mount uses the high-sensitivity differential �BD� micrometers. These micrometers feature both a course and a fine adjustment. This is the older version of the differential micrometer without the graduated thimbles. The sensitivity of setting is identical with the current micrometers, being approximately 0.1 micron.

Specification on this particular gimbal mount include:

Optic diameter � 25mm.
Optic thickness � between 1 and 12.5mm
Outside diameter � 89mm
Clear aperture of mount � 21mm
Approximate thickness of mount � 30mm (less micrometers)
Angular adjustment range � plus /minus 3 degrees

The mounts are in superb condition � micrometers fully functional throughout range. Photo is typical of condition. The mounts do NOT come with the adapter plate. Those are listed independently as SKU number DP252 (they are only available with the purchase of a matching type gimbal).

Klinger SK 25mm Gimbal Mount – missing clamps.

PLEASE NOTE � This mount is missing both the three spring-loaded fingers for securing optics on the reverse side of the gimbal mount AND the spring-loaded ring for conventional mirror mounting. Presently there is no means to secure the mirror within the gimbal short of cement. The spring-loaded rings from the much more common SL gimbal mounts will NOT work in these mounts.

This item is a Klinger Model SK Gimbal Mount for optics of 25mm diameter. These gimbals are somewhat more sensitive for mirror adjustment than the SL type gimbals. The SK mount is unusual in that there are two methods for securing optics or mirrors. The first method is similar to that found in the more common SL type gimbal mounts. There should be a spring-loaded ring with a pair of threaded posts to accommodate lenses or mirrors with edge thicknesses of up to 10mm. There is a recess in the gimbal mount machined for 51mm diameter lenses, with three precision bearing points that are perfectly matched to the common tilting planes for azimuth and elevation. The securing ring posts are slightly asymmetrical in order to allow easier exchange of the components via the larger of the openings. The minimum thickness for the mirror should be observed as the securing ring does not extend into the recess very far.

The second mode of mounting is for larger-than-specified 51mm mirrors. The recess on the opposite side of the ring mount is stepped and will accommodate mirrors in several sizes up to 78mm in diameter. The three spring-loaded arms (which are absent) would serve to secure the mirror into the appropriate recess. By reversing the mirrors so they face away from the mounting surface it is possible to use very steep grazing reflection angles.

Height & width of support� 80mm
Thickness of support � 25mm (30mm including gimbal plate)
Clear aperture � 22.5mm
Travel range (elevation and azimuth) � plus or minus 2 degrees
Minimum thickness for ring-mounting � 6.35mm

This particular mount is equipped with the Type BM standard micrometers for both the azimuth and elevation..

The mounts are in excellent condition. They do not come with any mounting plates or bases. Klinger part number (with BM micrometers) is 133 301.
