6.2 Mechanics
Adaptor rings
The adaptor rings are normally used to match thediameter of actuators with casing to mirror mounts,
defined for a distinct mirror’s diameter. An often

used combination are ring actuators (e.g. with casing VS22), which are adopted to 2” mirror mountsystem. The proper adaptor ring is an AR (51/22).

6.3 Optic adaptor for ring actuators
Ring actuators are often used within optical arrangements for precise adjustment of transmissive opticalcomponents e.g. within laser resonators or tunableetalons. The optic adaptors allow the simple mounting and changing of circular optics with the standard diameters 1/2” and 1”.
Optic adaptor OA ½”
This element allows mounting of optics with diameter 1/2” up to a thickness of 8 mm. It can be simply attached using the M12x0.5 thread to all thecorresponding ring actuators with a HAg M12x0.5
end piece (bare rings) such as theHPSt 150/14-10/…, or the equivalent cased types
with a VS22 casing.
Optic adaptor OA 1”
This element allows mounting of optics with diameter 1” up to a thickness of 8 mm. It can be simplyattached using the M22x0.5 thread to all the corresponding ring actuators with a HAg M22x0.75 endpiece (bare rings) such as the HPSt 150/20-15/…

sphereMagnetic front pieces
Based on the above described front adaptors,
MA components with magnetic plane face areoffered for VS10 and VS12 casings (designation
MA10 / MA12). Small ferromagnetic components
can be easily attached to the moving pin of stackactuators.
