The Model 8816-6 combines the stability of our Stability mounts with the precision and stiffness of our Picomotor actuators to provide the ultimate in precision motorized optical alignment. The compact Picomotor actuator housing adds only 0.75" (19.1 mm) to the overall thickness of these mounts. And, with two standard Picomotor actuators to provide tip and tilt adjustment, you have complete remote control. The unique optic-retention system minimizes wavefront distortion of the mounted optic as well as maximizes overall mechanical stability. Mirror installation and removal is simple and fast, requiring no adhesives.
All our vacuum-compatible and ultrahigh-vacuum-compatible Picomotor actuators come with short, Teﬂon®-coated leads so you can make connections to your vacuum-chamber feedthrough. If, however, you are also working with X-rays or other high-radiation applications, we recommend ordering a custom version where the leads are extended with Kapton®-coated wires. While Teﬂon is compatible for use in high-vacuum environments, it is not recommended for use in high-radiation applications where, with repeated exposure to X-rays and other radiation, it can degrade and fall off, possibly causing electrical shorts. So, if youre using our Picomotor actuators in a high-radiation application, contact our tech support for ordering these customized versions.
The Model 8817-6-V is the vacuum-compatible version of the Model 8816. It offers ultraclean materials and components along with vacuum-compatible Picomotor actuators. Two -V vacuum-compatible Picomotor actuators provide full remote-control tip and tilt adjustment. As all our vacuum-compatible products, the Model 8817-V is characterized using standard Gas Chromatography-Mass Spectrometry analysis (GCMS). It has been measured to outgas less than 0.1 ppm of volatile mass at 85 °C over three hours. Mass spectrograms detailing the exact outgassing compounds are available on request.
Refer to the following deﬁnitions to clarify our many different options with our Picomotor actuators:-V This is our standard vacuum-compatible option which is rated to 106 Torr.-UHV This is our ultrahigh-vacuum-compatible option which is rated to 109 Torr.
