8MPR16-1 - Motorized Polarizer Rotator

Motorized Polarizer Rotator
Waveplates, polarizers, prisms rotator

Ultra-thin compact design

For 1’’ (25.4mm) optics by default

Low optical axis height

High stability and accuracy

Cage system compatibility

Adapters for other optics dimensions available

8MPR16-1 motorized polarizer mount provides smooth, high accuracy, high repeatability and stability continuous 360° rotation of the polarization optical components with diameters up to 1’ (25.4mm) or 1/2’ (12.7mm), Glan Taylor prisms and other objects. Ultra-thin profile of the stage minimizes difficulties of polarizers integration  in optical schemes and systems with small gaps between elements. Motorized polarizer rotator has a low optical axis height relative to the mounting base. Additional plates installation on the rotator for 30 mm and 60 mm cage systems are allowable.  There are two fluoroplastic rings and two retaining rings for 1’ (25.4mm) optics fixing which are included in standard stage set.

Motorized Polarizer Rotator has M4 mounting holes at the sides of the motorized rotator for fixing it according to the requirements, available space and situation. It can be fixed on mounting posts or connected with adjustable plates and angle brackets. Stage can be used in horizontal position using base plate 3BP8MPR16-1.

8MPR16-1 can be equipped with adapter for prism up to 16 x 16 mm, also with adapter for 0.5 inch optics or rotating platform with M3 holes.
