Heliopan 37mm Circular Polarizer Slim Filter
Key Features
  • Minimize Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Enhances Color and Tonal Saturation
  • Slim 5mm-Thick Ring, No Front Threads
The Heliopan 37mm Circular Polarizer Slim Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

Heliopan 37mm Circular Polarizer Slim Filter

Heliopan 703780 Overview

The Heliopan 37mm Circular Polarizer Slim Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a slim brass filter ring for durability as well as jamming prevention. Its 5mm-thick profile does not have front threads in order to minimize the likelihood of vignetting with wide-angle lenses.

Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.
Lessens haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° from the sun.
Single coatings on both the front and rear offer protection to the glass and help to improve light transmission and image quality.
Constructed from Schott glass for optical clarity.
Brass filter ring helps to prevent jamming and provides additional strength.
Slim 5mm-thick filter ring does not have front filter threads in order to alleviate the likelihood of vignetting with wide-angle lenses.
