Polarising Filters

PR032 rotating linear polarisers are used to reduce glare and reflections from reflective surfaces.

The rotating mount allows the filter orientation to be adjusted for optimum glare reduction and stress pattern visibility.

A locking thumbscrew prevents accidental movement caused by vibration or cleaning, maintaining consistent optical performance.

These filters are also available in slip mount and quick mount configurations for lenses without filter threads.

PC052 circular polarizers are designed for applications using beam splitters, such as SLR cameras and camcorders.

These filters reduce glare while maintaining correct exposure readings for autofocus and autoiris systems.

The incorporated quarter-wave retarder rotates polarized light to prevent interference with internal light meters.

PI035 infrared linear polarizers are designed specifically for near-infrared imaging applications.

Unlike visible-light polarizers, these filters provide effective polarization performance in the 850-2000nm range.

Rotating and fixed mount versions are available, with locking thumbscrews preventing accidental movement.

Infrared polarizers are also available in slip mount configurations for lenses without filter threads.

PSxxx polarizing sheets are designed for mounting in front of lighting systems to polarize illumination sources.

Sheets are available in a range of sizes and thicknesses for custom optical integration applications.

Custom laser-cut laminated glass and plastic sheet materials are also available for specialised machine vision systems.
