Camera Lens Infrared Filters

Infrared filters block visible light and pass infrared wavelengths so the camera sensor records IR-only images; use them for creative infrared photography, monitoring plant health, or scientific applications where visible light needs to be eliminated

Choose by the cutoff wavelength (e.g., 720nm, 850nm, 950nm): lower cutoffs (around 660–720nm) pass some deep red for milder IR effects and easier exposure, while higher cutoffs (850nm+) produce stronger IR rendering but require longer exposures and sensors with IR sensitivity or modified cameras

Most IR filters are glass screw-in or square-format filters sized by front thread diameter or filter holder; verify your lens filter thread size or choose an appropriate holder adapter and ensure your camera's sensor can respond to the IR band you plan to use

IR filters greatly reduce visible light so plan for longer exposures or higher ISO, and note that infrared focuses slightly differently than visible light—many lenses focus shift in IR, so use live view or focus peaking at the shooting wavelength or pre-focus and use manual focus adjustments

Yes — IR captures often produce monochrome or false-color results depending on sensor and filter; post-processing typically involves channel swaps, white balance adjustments, and contrast/tone work to achieve desired infrared aesthetics

Handle filters by the edges, clean with a microfiber cloth and appropriate lens cleaner or air blower to remove dust, avoid abrasive materials, and store them in a padded case or original packaging to prevent scratches and moisture

IR filters span budget to premium levels — expect options under $50 for basic glass up to higher-priced multi-coated or specialty filters; coatings, optical quality, and mechanical build vary by brand and will affect durability, flare control, and color consistency
