Knight Optical can offer Circular Sheet Polariser for use within Photographic Applications. We supply a range of Circular Sheet Polariser for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers within Photographic Applications. Our Circular Polarisers consist of a quarter wave plate cemented to a linear polariser. While a linear polariser may be used to reduce glare during photography (such as reflection from the surface of a body of water), autofocus systems struggle to correctly focus on linearly polarised light. With the addition of the quarter wave plate, this has little impact on the intensity of incident light to the sensor, but it makes autofocussing much easier. For more information read PDF…
