Kolari Infrared Lens Filter - 665nm

Create artistic false-color or B&W infrared landscapes with sharp details and flexibility in contrast.

Kolari Vision Infrared Filter 665nm - Image Example

Transform your photography with the Kolari Vision 665nm Infrared Lens Filter. This filter can produce vibrant false colors with good B+W contrast. It is typically used to produce light yellow leaves or the classic white IR look with blue skies. | With Kolari Vision’s precision engineering and superior optical quality, you can achieve exceptional clarity and detail in every shot. | This filter requires post-processing.

This filter requires a full-spectrum converted camera, or an infrared camera converted to a lower wavelength, such as the 550 or 590, to produce the desired visual effect.

Uncoated glass, like in our standard IR filters, has a reflection of around 7.7% at all wavelengths (about 4% when the light enters the glass, and another 4% when the light exits the glass). For our Pro Gen 3 IR filters, we developed an IR centered anti-reflective coating that reduced the ~7.7% reflection down to <0.4% on average over the IR band, reducing ghosting and glare while increasing overall transmission from 90% to 98%. We also topped our Gen 3 filters with a hydrophobic anti-smudge scratch resistant coating to increase durability and make cleaning easy.

We understand that post-processing IR images can be challenging at first but don’t worry, we have many resources and tutorials available for IR photographers. Here are a few of our most popular IR post-processing resources below:

how to find filter thread size
Finding the Right Filter Size for Your Lens
Before placing your order, please double-check your lens’s filter thread size, not your camera model or lens focal length. The correct filter size is usually printed on the front or side of the lens, or underneath the lens cap. Look for a number next to the diameter symbol (ø), such as ø77mm—this is the size of the filter you need. Important: Your lens’s focal length (e.g., 70–200mm) is not the same as the filter thread size.
