Synthetic Linear polarising
filters (polarisers) possess special properties for selectively
absorbing light vibrations in certain planes. When unpolarised
light, which is a complex mixture of vibrations lying in all
possible directions transverse to the line of travel, is passed
through a linear polariser its vibrations become confined
to a single linear plane and the light is considered “polarised”.
This linearly polarised light can be modified to suppress
unwanted reflections and to eliminate glare for a variety
of applications.

Polariser: HN32
Type: Neutral linear polariser
Features: Represents the best balance between transmission and extinction for general use. Extinction transmission is about 0.005%.
Typical Applications: Variable density filter systems, photoelastic stress analysis and other application where light modulation is necessary. |
Polariser: HN38
Type: Neutral linear polariser
Features: Exceptionally free from colour distortion.
Typical Applications: Camera filters, studio light filters, variable colour filter systems, other applications where high transmission is required along with a medium extinction density. |

Polariser:
HN42
Type:
Neutral linear polariser
Features:
