Product Features
Nanometer-Precision Single-Axis Positioner
Honeybee has designed and developed precision actuators, under funding from NASA GSFC, intended for micro-positioning of the Next Generation Space Telescope (later renamed James Webb Space Telescope) primary mirror.
The design of the Nanometer-Class Actuator is based on gear-bearing technology previously developed by Honeybee. The actuator is capable of achieving small displacements and high forces and can operate at cryogenic temperatures. There are 3 configurations that have been designed; the device is about 1.7 inches in diameter by 2.5 inches in length, with a mass ranging from 180 to 350 grams. The current configuration has a mass of 350 g, 6 mm full linear stroke, and 12 nm output displacement for every 1.8 degree motor step.
