The Heliopan Bay 6 Kaeseman Linear Polarizing Glass Filter is constructed from select polarizer foils and especially prepared optical glass. Kaeseman ("encased") filters are completely edge-sealed for maximum durability under extreme climatic conditions.
Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast.
The effect can be seen through the viewfinder and varied by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
Heliopan Lichtfilter-Technik of Munich, Germany, has changed their black anodized brass filter rings on most Heliopan non-rotating filters to their "slim" mounts. These slim mounts are made of black anodized brass stock and have so little rim in front of the lens (5.4mm) that they will not vignette with lenses as short as 21mm.
Heliopan offers a wide selection of sizes, screw-in, series, bayonet, square and rectangular filters including digital, video, center weighted, graduated, wide angle, Kaesmann polarizers, drop-in polarizers, etc.
Note! Linear polarizers are used with most video and manual focus photo cameras. They are not recommended for auto-focus SLR cameras. his filter is specific to lenses with Rollei's exclusive B6 (Bay 6) filter size
- Fully calibrated to indicate the axis of polarization and the convenient markings make the filters very easy to use on non reflex and non ground glass focusing cameras.
- With the calibrations all that is necessary is to hold the filter up to the eye and rotate it until the desired effect is seen. Note the position of any number on the rim, mount the filter on the lens and rotate the mount till the selected number is in the same position as when the filter was held to the eye.
- Heliopan cuts, grinds, polishes and coats their filters with the same techniques and equipment as used for the finest German camera lenses.
- All Heliopan screw-in type and series size filters are mounted in precision black anodized brass rings to eliminate binding or cross threading and to ensure optimal alignment.
- Filters still retain front threads for a lens cap, a lens hood or even stacking a second filter.
- The portion of the Heliopan slim filters that are in front of the lens have been reduced in thickness by 37% over the former mount.
