The Schneider 4.5" True-Cut 680 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 cinematography camera becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame.
When the Schneider 4.5" True-Cut 680 IR Filter is used along with multi-stop neutral-density filters, it blocks 50% of visible light waves at 680 nanometers. At 700 nanometers, 90% of infrared light waves are blocked, after which they are progressively eliminated. 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 750 IR filter moves the point at which 50% of light is blocked into the infrared spectrum to 750 nanometers. While that 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 cause color shifts frequently associated with high-definition recording.
Mounted without front or rear threads for use in third-party or custom filter holders for film and television cameras.
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.
Padded pouch for storage and transport.
