Burleigh 2-inch Gimbal Mount with Elevation
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.
This mount includes a special Piezo actuator bearing pad for the elevation micrometer. The actuator does not include the connection cable or the control unit to ramp the Piezo. The special Piezo system allows extraordinary positional sensitivity.
Both axes have 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, support bracket and Piezo units. Condition of everything is superb. The mounts have been rebuilt and the micrometer spindles cleaned and relubricated. The gimbal plates in these mounts are cast steel, not the much lighter aluminum alloy.

Burleigh SG201 2in Gimbal Mount and Angle Bracket
Burleigh SG201 2″ Gimbal Mount and Angle Bracket
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 lack the optic carrier portion.
This version is a bit earlier – the micrometer spindles lack the large plastic adjustment rings for increased setting sensitivity. 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 removable optic carrier is missing from this mount – currently there is a clear bore of 2.255 inches diameter. One could easily fabricate a mirror holder to fit the bore.
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. The rear portion of the angle plate has been milled away (see photo).
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 dimension is 4 inches by 2.70 inches (base used to be 4 inches long). The reference plane lies approximately 0.875 inches from the front of the base plate.
Listing includes gimbal mount and modified support bracket. Condition of everything is superb. The mounts have been rebuilt and the micrometer spindles cleaned and relubricated. The gimbal plates in these mounts are cast steel, not the much lighter aluminum alloy

Lansing 1.5in Gimbal Mount with 2-inch Micrometers
Lansing 1.5 inch 38mm Gimbal Mount with 2-inch Micrometers
These Lansing gimbal mountings are capable of holding optics or mirrors up to 1.5 inches in diameter. The mounting ring has three threaded holes on both the front and rear faces. The lens would be retained either by a pair annular rings or by small tabs at each of the thread locations. These will need to be provisioned separately � they are not included with the mount.
The other unusual feature on this mount is that the setting spindles for the azimuth and elevation are 2 inch range of motion, but only a small portion of this range may he employed. The spindles are engraved Lansing, so they are the original spindles. I can only surmise they were employed so the mount could be manipulated well away from the optic axis.
Optic axis height � 2.25″
Optic Dianeter – 1.5″
Base width � 4″
Base length � 4″
Range of motion � at least plus or minus 5 degrees
Graduated 2″ micrometer spindles
The mounts are in excellent condition and fully functional. Magnetic bearing pads keep the gimbal mounting rings in contact with the anvil of the setting spindle micrometer.
