MidOpt Polarizing Filter Pi031
Uniforce Product
Salient Features
Near-Infrared Linear Polarizer, High Extinction
Maximizing the reduction of glare in the near-infrared and visible spectrums, because of its construction, this rotating polarizer is also excellent in situations where temperatures may reach up to 100º C (212º F). The rotating mount makes it easy to determine the point at which glare reduction is maximized, while the locking thumb screw available on all MidOpt mounted polarizers secures the filter’s position.
Best results are achieved when a corresponding linear polarizing film is used over the light source.

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
