Salient Features
Circular Polarizer
Used to eliminate specular reflections and hot spots, Circular Polarizers in rotating mounts allow maximum flexibility and ease of use. However in most machine vision applications we recommend the use of linear rather than circular polarizers. Circular polarizers are recommended for eliminating glare from spherical surfaces or in cases where an auto-focus or metering system are used involving a beamsplitter or mirror mounted in the optical path inside the camera.
Best results are achieved when circular polarizing film is also used over the light source. Left-handed and polarization directions are available.

Slip Mount
- Designed for varifocal lenses, wide angle lenses and lenses without filter threads
- Accommodates standard threaded mounts
- Low profile and oversize diameter design prevents wide angle lens vignetting
- Locking set screws and a wrench are provided to secure the adapter to the lens
- Many varifocal and shorter fixed focal length (wide angle) lenses are not supplied with filter threads due to the presence of a protruding, strongly convex lens element. Our slip mount adapters allow standard threaded filters to be fitted securely to these and a large variety of lenses that do not have filter threads provided.
Ordering Example:
- Filter: BP470
- Outside Diameter of Lens in mm: 43mm
Correct Part# is:
- BP470-S43
