MidOpt Polarizing Filter Pi035 t

Uniforce Product

Salient Features

Near-Infrared Linear Polarizer, High Transmission 

Particularly useful for minimizing glare in light-starved applications, these wire grid polarizers are also well-suited for applications involving high heat. The rotating mount makes it easy to orient the polarizer, finding the point where glare is minimized. The locking thumb screw available on all MidOpt rotating polarizers insures that accidental jarring or repositioning does not occur.

Best results are seen when this polarizer is used over the lens in conjunction with an appropriate polarizer film 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.
