Schneider 4.5" Round 1/4 Wave Retarder Filter (Mounted)
Key Features
  • Polarization Control Filer
  • For 3D Cinematography
  • Prevents 3D Camera Image Disparity
  • 1.25x Filter Factor, +0.3 Stop
The mounted Schneider 4.5" Round 1/4 Wave Retarder Filter is a polarization control filter that is designed for 3D cinematography. The process of recording 3D video employs a reflected image from the silvered surface of a 3D rig's beamsplitter. In instances where the recorded image contains glare, partial polarization can occur as the light entering the 3D rig is reflected from the silvered surface. This can result in disparity between the left and right optical paths created in part by the beamsplitter, and ultimately, a compromised 3D effect.

Schneider 68-011045 Overview

The mounted Schneider 4.5" Round 1/4 Wave Retarder Filter is a polarization control filter that is designed for 3D cinematography. The process of recording 3D video employs a reflected image from the silvered surface of a 3D rig's beamsplitter. In instances where the recorded image contains glare, partial polarization can occur as the light entering the 3D rig is reflected from the silvered surface. This can result in disparity between the left and right optical paths created in part by the beamsplitter, and ultimately, a compromised 3D effect.

When this Schneider 1/4 Wave Retarder Filter is used with a 3D rig, partial polarization from the beamsplitter is prevented, helping to ensure that the left and right optical paths have identical properties for a consistent 3D effect with no reduction in resolution.

Designed for use with 3D camera rigs to control for polarization that can result from optical path disparity.
Helps to ensure a consistent 3D effect.
1.25x filter factor reduces exposure by 0.3 stop.
Constructed from water-white glass for optical clarity.
Plastic filter case for storage and transport.
