The KipperTie IR Spectrum Filter for RED is the "night shooting mode" for your DSMC2 system. Unlike its full-spectrum sibling, this filter only passes near-infrared beyond 720nm. Developed over two years for our high-profile, adventurous natural history film clients, this filter provides the ultimate in IR imaging with exceptional sharpness. The filter has protective, anti-reflective coatings and comes housed in a genuine RED interchangeable holder. Version 2 of the IR spectrum filter improves anti-reflection by up to three points, improves NIR transmission by approximately 10% and has a more robust surface finish for easier handling.

What is the difference between full spectrum and IR spectrum versions?

All regular OLPFS attenuate UV, IR and visible wavelengths to control color reproduction, bringing it as close as possible to the human experience of color. The Full Spectrum filter allows the camera sensor to see the full range of wavelengths to which it is naturally sensitive. This means that you will have a color image, the color of which is distorted by the presence of IR light. IR light is invisible to us, so its presence is difficult to predict, but many light sources produce it. Additionally, many surfaces, especially leaves, fur, and artificial fabrics reflect a disproportionate amount of IR, creating unexpected brightness and contrast. The IR spectrum filter removes all visible light from the image, but allows the camera to see infrared light (720nm to 950nm) that would otherwise be filtered out. The result is a low-contrast, pink-toned monochrome image that represents only this invisible light. Many objects have a very unusual appearance, blue skies darken, skin becomes almost translucent, and direct IR light sources such as LEDs become incredibly powerful and bright.

It can be used for applications such as:

• Infrared illuminated covert filming
• Infrared landscape images
• portrait images
• Creative and scientific purposes.
