Gobe G40JOCPL Overview

  • 1Description

The Gobe 40.5mm 2Peak Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This filter is constructed from optical glass that is set within a magnalium-alloy filter ring for enhanced durability while remaining lightweight. To prevent internal ghosting and reflections, each glass surface includes 16 layers of anti-reflection coatings on each side. These coatings also offer scratch protection to the filter substrate while promoting clarity as well as color fidelity, which results in an improved beading effect when in contact with water or oil for more efficient cleaning.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
2.3 to 2.8x filter factor reduces exposure by 1.2 to 1.5 stops.
Constructed from optical glass.
16-layer multi-coating to prevent internal ghosting and reflections while promoting clarity as well as color fidelity.
Coatings also help prevent scratches and result in an improved beading effect when in contact with water or oil for greater cleaning efficiency.
Magnalium-alloy filter ring for enhanced durability while remaining lightweight.
Filter ring can be rotated to adjust the intensity of the polarization effect.
40.5mm front filter threads allow for use with other filters.
Metal filter case for storage and transport.
Microfiber cloth for cleaning and maintenance.
