Infrared Filter B+W Basic 092 (695 nm) 77 mm - B&W 1102768

B+W Basic 092 Infrared filter (695 nm) in 77 mm screw-mount format is designed to transmit infrared light while substantially reducing visible light. The glass element selectively passes radiation around 695 nanometres, enabling photographers to record infrared-only information with compatible cameras or modified sensors. The compact, threaded design fits lenses with a 77 mm front thread and is intended for creative infrared photography where long exposures, enhanced foliage contrast and strong monochrome effects are required.

Advantages

The filter provides reliable infrared transmission at the specified wavelength while blocking most of the visible spectrum, producing distinct tonal separation and increased contrast in foliage and skies. Its 77 mm screw-mount makes it easy to attach to commonly used lenses without additional adapters. The optical glass is housed in a slim metal ring to reduce vignetting on wide-angle lenses and to maintain a low profile for stacking with other filters when required.

Suitable for

• Landscape infrared photography with long exposures
• Artistic monochrome and experimental imaging
• High-contrast foliage and sky separation
• Camera systems or sensors modified for infrared capture

Key specifications

• Thread size: 77 mm screw-mount compatible with lenses having 77 mm front thread
• Peak transmission region approximately 695 nm (infrared)
• Optical element: infrared-transmitting glass
• Mount: slim metal frame designed to minimize vignetting

How to use

Attach the filter to a lens with a 77 mm front thread by screwing it on until secure. Because the filter blocks most visible light, use longer exposure times or higher ISO settings as needed; a tripod is recommended for stability during long exposures. Compose and focus before fitting the filter when using a camera without live-view that cannot preview infrared; for live-view or modified cameras, verify focus after mounting as infrared focus shift can occur. Post-processing may be required to convert captured infrared images to monochrome or to adjust white balance and contrast.

Usage recommendations

For best results in landscape and foliage shots, shoot in bright daylight to achieve a stronger infrared response and use a tripod for long exposures. When using wide-angle lenses, the slim frame helps reduce vignetting; however, test exposures and check corners for any darkening. Store the filter in a protective case when not in use to avoid scratches and dust on the optical surface.
