A-CR Porous Graphite Air Bearing Pad CR40R
The A-CR series uses porous graphite with an internal porous structure that forms a uniform air film when supplied with air. It is a key component for assembling air bearings and air-bearing linear stages, offering straightness and flatness beyond conventional mechanical guides. It is especially suited to small-step or ultraprecise positioning applications and is an excellent choice for precision optical adjustment, assembly and machining.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
