Waveplate Holders

Rotation holders for positioning rotation-sensitive optics such as polarizers and waveplates. Most offer continuous 360° rotation on roller bearings with engraved angular scales and locking; versions include high precision mounts with micrometer-driven fine rotation and side-drive holders with tilt/tip adjustment. Holders accept 1", 2" or 3" diameter optics, and the range also includes simple retardation plate holder rings.
