Optical polarizer holder

motorized

Motorized Optics Holders * Five-phase stepper motor * 360 degree continuous motion * Positional repeatability to ≤0.02 degrees * Compact design The SGSP Series motorized optics holders utilize the unique Five-phase stepping motor and high-precision actuators to provide precise controlled stepping movements. The motorized optics holders offer smooth continuous 360 degree movement and positional repeatability to within 0.02 degrees. These features make them suitable for many laboratory and OEM applications. The motorized optics holders are available in Glan-Thompson prisms, wave plates and variable ND filters versions. The Glan-Thompson and wave plate mounted versions can control the polarization of light by automating the rotation of the polarizers. The variable ND filter wheels are convenient tools for adjustment of beam intensity. They can be mounted in an optical path and rotated to increase or decrease the beam attenuation. The filters have a 0.04-2.7 variation in optical density over the full rotation. There are two types offered, BK7 and synthetic fused silica.
