Overview

The B+W 46mm Kaesemann High Transmission Circular Polarizer MRC Filter minimizes reflections and glares by filtering out polarized light that reflects off non-metallic surfaces. The light from the sun becomes partially polarized due to reflecting off electrons in molecules of air, causing it to scatter and make images appear hazy. The filter arranges the polarized light perpendicular to the reflected light to allow for better absorption, resulting in a noticeable reduction in glares and reflections from non-metallic surfaces. The circular polarizer contains a quarter wave plane in addition to the linear polarizing filter. The quarter wave plane allows the use of autofocus and exposure functions. The filter includes Kaesemann HTC polarizing foils, and they are placed between plano-parallel optical glass. To prevent internal ghosting and reflections, each optical glass surface has an anti-reflective coating. The filter substrate even has a multi-resistant coating that helps it to stay clean for longer.

Detailed Specifications
Front Accessory Thread Size:	46mm
Front Accessory Thread Size: An adapter that allows threaded accessories to filter kits, such as Lee's Foundation Filter kit. View All Attribute Definitions
Filter Type:	Circular Polarizer
Filter Type: The type of filter for a lens. Filters can be screwed on the front element or dropped in for larger zoom lens. View All Attribute Definitions
Multi-Coated:	Yes
Multi-Coated: A series of optical coatings that are on a lens/filter that help reduce the impact of reflections. The result is a higher transmission percentage of light. All modern lenses are multi-coated. View All Attribute Definitions
Filter Construction:	Schott Glass
Filter Construction: This is the construction of a type of filter. The type of process used to create a filter can affect its price. Filters can be constructed out of regular glass that sandwiches a coloured gel in between or in high-end filters, raw elements are added to the molten optical glass so there is no risk of uneven colour or fading.

Filter Effect:	Eliminates reflections and haze and improves color and tonal saturation
Filter Effect: Allows various filter effects to be done in-camera while shooting. Common filter effects are vivid, neutral, sepia, black and white, negative, cooling, warming, etc... View All Attribute Definitions
Front Lens Cap Size:	46mm
Front Lens Cap Size: This is the size of a front lens cap. Standard sizes for snap-on lens caps include: 27mm, 28mm, 30mm, 34mm, 37mm, 39mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm and 86mm. View All Attribute Definitions
Filter Factor:	2 to 2.8 (1 to 1.5 stops)
Filter Factor: When placed in the optical path, many filters block a certain amount of light from reaching the lens. Filter factor relates to how much exposure compensation is required in order to adjust for this. Most cameras have TTL metering and will be able to do this automatically.
