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. Polaroid Linear Polariser Transmission Polariser: HN32Type: Neutral linear polariserFeatures: 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: HN38Type: Neutral linear polariserFeatures: 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: HN42Type: Neutral linear polariserFeatures: High transmission. Typical Applications: Photographic, spectrographic and other applications where insertion losses must be kept to a minimum.
