The B+W UV-IR Cut 486 MRC Basic Filter (49mm) is a 49mm ultraviolet and infrared control filter that is useful for digital cinematography and still photography. When used, 88% of ultraviolet light waves are blocked at 380 nanometres, along with 95% of infrared light waves at 700 nanometres, ensuring that light limited to the visible spectrum is recorded. When used along with multi-stop neutral-density filters, potential infrared colour shifts are prevented or minimised, preserving colour accuracy throughout the frame. This filter also reduces unwanted blue castes while recording digital video or still photos under daylight that also features intense ultraviolet light.
Features
- 88% of ultraviolet light waves are blocked at 380 nanometers, before which they are further removed, reducing bluish cast of daylight when recording video or still photos.
- 95% of infrared light waves are blocked at 700 nanometers, after which they are progressively eliminated.
- Useful with CCD or CMOS sensors to filter out infrared light pollution that causes color shifts frequently associated with high-definition recording with multi-stop neutral-density filters.
- Does not require adjustments to exposure while in use.
- Thirty layers of interference coatings on the front surface limit light that falls on a digital camera sensor to the visible spectrum.
- Multicoated rear surface prevents internal ghosting and reflections.
- Constructed from Schott glass for optical clarity.
- F-Pro brass filter ring helps to prevent jamming and provides additional strength.
- 55mm front filter threads allow use with other filters to protect the front surface or combine with other effects.
- Plastic case for storage and transport.
