Infrared Photography Filter

The B+W 092 Infrared Filter is a 67mm accessory built for digital and film photographers exploring infrared imagery. Its nearly opaque dark purple glass blocks all visible light up to 650nm, transmitting only the infrared spectrum for surreal, high-contrast results.

F-Pro Brass Ring Compatibility

The filter mounts via an F-Pro brass ring that resists jamming and threads onto any lens with a 67mm front diameter. The uncoated Schott glass maintains optical clarity without adding reflective layers, leaving the front element free for lens caps or hoods that match the same thread size.

Variable Exposure Behaviour

Because the filter factor changes with film sensitivity and lighting, exposure must be determined per scene rather than by a fixed multiplier. The glass passes 50% of light just below 700nm and over 90% from 720nm to 2000nm, so extended exposures are typical and results shift as infrared intensity varies through the day.

Questions about this item

How much visible light does the 092 filter block before 650 nm?

The filter blocks all visible spectrum light up to 650 nm, allowing only 50% transmission just below 700 nm and over 90% from 720 to 2000 nm.

Will the uncoated Schott glass and brass F-Pro ring overheat or make noise during long exposures?

No — the filter is passive glass with no electronics, so it produces no heat or noise regardless of exposure length.

What thread size must my lens have for this 67 mm F-Pro filter to fit?

Your lens needs a 67 mm front filter thread; the brass F-Pro ring then screws on directly without an adapter.
