There are several good reasons for using an IR-cut filter. Using a color camera to achieve realistic colors in white light requires an IR-cut filter. ... A CCD color camera in daylight without an IR-cut filter will therefore see a significant amount of infrared light resulting in strange colors.
What is an IR blocker?
Block-IR consists of two layers of infrared-blocking material bonded with polyurethane, which surrounds a core of non-conductive insulation. When sealed with foil tape, it creates a barrier that locks the heat and infrared light in.
How does IR photography work?
Infrared film works by being formulated to record infrared light particles. The catch is that these films are also receptive to light from the visible spectrum as well. To solve this problem and in turn make photos using infrared film, you will need an infrared filter for your lens.
What is IR Blocker?
Block-IR consists of two layers of infrared-blocking material bonded with polyurethane, which surrounds a core of non-conductive insulation. ... When sealed with foil tape, it creates a barrier that locks the heat and infrared light in.
What does a IR filter do?
Infrared cut-off filters, sometimes called IR filters or heat-absorbing filters, are designed to reflect or block near-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating.
How do I know if my camera has IR filters?
While viewing your digital camera's LCD screen (never through an optical viewfinder), point your TV remote at the front of your lens and press any button on the remote. If you can see a light beam emitting from the remote, then this means your camera is infrared sensitive.
How do I block near infrared?
Any electrically conductive material will block IR. The greater the conductivity, the greater the blocking. Aluminum foil will kill all IR, bot high range and low. Most plastics allow IR to pass through.
Do ND filters block infrared?
ND filters cut down visible light, but don't cut down light in the infrared spectrum.
Can you use ND filters with an infra red sensor?
Most ND filters will also work in infrared light, just make sure it's made of glass as plastic and resin filters tend to only work in visible light and pass IR light unaffected.
What is an IR ND filter?
Is a combination of both an infrared control filter and a neutral density filter. An IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination.
What is the function of ND filter?
Neutral Density (ND) filters reduce the intensity of all wavelengths, or colors, of light equally from entering the camera, in measured amounts. This allows the photographer more control in selecting shutter speed and aperture combinations in a variety of conditions.

How do you filter an infrared light?
- Add a filter, such as the Hoya R72 filter, in front of the lens. This will block visible light and let IR light to pass. ...
- Remove the IR-blocking filter from the camera. ...
- Remove the IR-blocking filter from the camera and replace it with a filter that blocks visible light and passes IR.
