This Gimbal Mount Mirror Holder System
provides very high resolution positioning with a freedom of +3║ movement and a <1
arc/sec. resolution with micrometers or <3 arc/sec. with precision spindles. With Piezo
Electric Translators the resolution can be fine tuned by a factor of ten.
This system is preferable at applications where any distortions or
vibrations of the tilt axes have to be kept to a minimum. The optic can be positioned in
the center of the tilt axis. The mirror is held in place by two nylon screws, holding the
mirror gently against two steel pins as solid reference support. This is especially
important with larger mirrors that might be subject to temperature distortions.
The Gimbal Mounts are supported in adjustable high quality sleeve
bearings to prevent any vibrations at micro positioning adjustment or at a controlled
frequency operation. Four motion control systems are offered:
- Precision Spindles with 0.35 mm pitch.
- Precision micrometers with a pitch of 0.25 mm and a scale of 0.005
- Drive-Master motorized positioning with hands-off or remote
manipulation. Depending on the gear ratio, adjustments of one radian can be achieved.
- Piezo Electric Translators may be added to the Micrometer Drive.
