Black 760nm Long Wave Pass Filter Infrared Pass Filter Near Infrared Imaging Of Colored Optical Glass

Azabooti presents the ir filter for near infrared imaging with a Black 760nm Long Wave Pass. This 8mm glass filter blocks visible light while transmitting beyond 760 nm for clear IR observations.

Capture true color and contrast in near-infrared imaging with this Black 760nm Long Wave Pass Filter. If you’re building or upgrading an infrared imaging setup, this compact filter helps you isolate the imaging band beyond 760 nm, delivering high transmittance in the desired range while cutting off shorter wavelengths. It’s an ideal addition for hobbyists, educators, and professionals who rely on clear, spectrally selective observations in low-light or dark environments.

Key benefits include sharp imaging in the near-infrared region, high peak transmittance, and simple integration into standard optical assemblies. The filter is designed to pass wavelengths above 760 nm while providing a tight cut-off below 700 nm, helping you minimize interference from visible light and improve contrast in IR observations.

Product highlights and specifications

• Material: Glass with a durable coating
• Color: Black coating for enhanced light suppression
• Diameter: 8.0 mm
• Thickness: 1.1 mm
• Wavelength range: 300–1100 nm (test range)
• Transmittance: Above 760 nm with peak transmittance > 92%
• Cut-off wavelength: Below 700 nm (imaging part of the spectrum)
• Cut-off depth: < 0.2

This filter is designed for use in near-infrared imaging systems, including cameras, sensors, or DIY IR projects where a compact, high-precision barrier to visible light is advantageous. The small form factor makes it suitable for integration into portable IR rigs, microscope setups, or light-tight housings where space is at a premium.

How to use

• Place the filter in the optical path where you need to suppress wavelengths below 700 nm and transmit wavelengths above 760 nm.
• Ensure a clean, dust-free mounting surface to prevent optical contamination that could degrade image quality.
• If you’re calibrating imaging performance, compare captures with and without the filter to observe improvements in IR contrast and color separation.

Note: The listed dimensions and tolerances are given to help with compatible mounting and alignment in standard optical fixtures. Actual color perception may vary slightly with lighting and monitor settings.
