Explore Scientific 2" Variable Polarizing Filter

While designed for universal application, this 2" Variable Polarizing Filter features a 2" filter thread, making it an essential tool for photographers and astronomers alike. The filter allows for continuous adjustment of image brightness, a feature that proves invaluable when dealing with strong contrast differences in various observation objects.

This variable polarizing filter is particularly effective during lunar and planetary observation, as well as solar observation, where it prevents the blooming of the finest details. However, it's important to note that solar observation should only be conducted in conjunction with a suitable sun protection filter.

The filter's versatility shines when used with a Herschel wedge or large lens openings, as it can reduce the brightness of the objects to be observed to a comfortable level. With a wide control range of 40% to 1% light transmission and a neutral gray filter effect, it delivers a pleasant and unadulterated image.

Operating this 2" Variable Polarizing Filter is straightforward. By simply turning the two halves of the housing, you can set the desired strength of the filter effect. The filter also features a two-sided 2" filter thread (inside/outside), allowing for the simultaneous use of other color filters. This feature enhances its functionality, making it a valuable addition to any photography or astronomy equipment collection.
