Schneider 68-121077 overview

  • 1Description

The Schneider 77mm True-Cut 750 IR Filter is an infrared control filter that is designed for digital cinematography. While recording video with a CCD or CMOS camera, multi-stop neutral-density filters are used to maintain proper exposure by compensating for increased light levels when widening the camera lens's iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop neutral-density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the sensor of a digital cinema camera becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.

When the Schneider 77mm True-Cut 750 IR Filter is used along with multi-stop neutral-density filters while recording with a digital sensor, it blocks 50% of infrared light waves at 750 nanometers before progressively eliminating them. This helps to limit the light that falls on the sensor to the visible spectrum, preserving color accuracy throughout the frame as potential infrared color shifts are prevented or minimized. A similar True-Cut 680 IR filter moves the point at which 50% of light is blocked into the visible spectrum to 680 nanometers. While a True-Cut 750 IR filter is sufficient for many cameras, others may have sensors that require a higher degree of infrared control, such as that provided by a Schneider True-Cut 680 IR Filter.

Designed for use with CCD or CMOS sensors to filter out infrared light pollution that causes color shifts frequently associated with high-definition recording.
For use on lenses or filters with 77mm front filter threads.
Ideal for use with multi-stop neutral-density filters.
Does not require adjustments to exposure while in use.
Constructed from water white glass for optical clarity.
Durable and lightweight aluminum-alloy filter ring
Plastic case included for storage and transport.
