RENT Schneider Optics 6.6x6.6" True-Pol Linear Polarizer

One-Stop True-Pol:

The One-Stop True-Pol is the latest addition to the popular Schneider True-Pol family. It significantly reduces reflections while reducing available light by only one stop.

Diamond-cut optical quality:

Diamond cut from crystal-clear, water-white optical glass, Schneider filters are ground and polished to a precise flatness and plane-parallelism (exact parallel relationship between front and back filter surfaces). To ensure perfection, this is verified by a laser interferometer. Schneider filters are then checked with a densitometer for consistent density, and tested with a spectrophotometer for proper light transmission. This ultra-high consistency allows cinematographers to swap like filters mid-shoot with no discernible variation in color or effect. The unprecedented purity, color saturation, and repeatability of Schneider filters virtually eliminate the need for lab color timing correction.

Rugged performance:

Schneider filters stand up to the most rigorous demands on set or location. Many feature Schneider's specially formulated hard anti-reflective (AR) coating to resist flaking, peeling, and scratching. This proprietary coating also reduces light loss and flare to less than 1% per surface, compared to untreated glass that has a light loss of 4% per surface. Schneider screw-on filters feature virtually jam-proof brass precision mounting rings, while unmounted Schneider laminated filters are protected against delamination and edge-chipping by Schneider's unique Edge Seal, which also reduces edge reflection and flare.

Long lens compatibility:

The common perception among photographers and cinematographers is that filters should not be used in front of long-length lenses, due to the critically short depth of field of these lenses. This belief is often confirmed when poorly made glass or plastic-resin filters are placed in front of a long lens, where image degradation is visible simply by looking through the viewfinder. This degradation is caused by poor quality control, low-quality glass, and poor glass grinding and polishing techniques.

Schneider filters have no such problems and can be used in front of even the longest lens. Diamond-cut from high-quality optical glass, then ground and polished to precise lens-making standards, Schneider filters offer unsurpassed clarity, light transmission, and color saturation with no visible compromise of image quality. Even when stacked, they remain the clear choice for use with any lens.
