Kolari Pro Gen 3 Infrared Lens Filter





Our industry leading Infrared lens filters, perfected.

We’ve taken our market leading infrared lens filter glass and upgraded it to meet the demands of our professional clients. Our Anti-Reflective, Anti-Smudge, High-transmission IR glass is now fitted with precision machined brass rings, enhanced grip, and a superior lifetime warrantied construction while maintaining a low profile over your lens. Like our Gen 2 glass, these filters are coated with an ultra-smooth, hydrophobic AR coating that increases scratch resistance and causes dust, smudges, fingerprints, water, and even permanent marker to slide right off its surface with minimal effort.

These external infrared filters are perfect for adding to a full spectrum conversion or on top of another infrared conversion to get a different effect. These are high quality polished optical glass IR filters, each with standard front and back threads.

These professional grade filters are our finest filters to date. All of our pro filters are Anti-Reflective and Anti-Smudge coated and come in our low-profile brass filter ring.

AR Coating


Uncoated glass 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), and we found that these reflections off the sensor filter was bouncing off the glass and reflecting back from the lens housing and aperture blades to contributing to the hotspots.  We developed an anti-reflective coating that is centered around the IR wavelengths that cause hotspots, and reduced the ~7.7% reflection down to <0.4% on average over the IR band, compared to our competitors coating which reduces <1.0%. Below, scan data from our sensor filter coating compared to uncoated glass.

Lens Filter AR Coating

We also now offer our AR coatings on our IR filters and hot mirror filters. The AR coating reduces increases transmission and reduces reflections and ghosting.  Example below of one example of a filter reflection artifact.

3 reviews for Kolari Pro Gen 3 Infrared Lens Filter

  1. Jaswant Madhavan

    I have been dealing with Kolari Vision and their line of filters for about 3 years now. I have always found them especially responsive and thoroughly professional. the filters are of exceptional quality and are a dream to work with.

  2. Isarawut Sresthadhigupta Krasienapibal

    I tried cheap IR filter with half the price once. The quality was ok but I’m looking for something better then I tried Kolari.
    The quality is far superior in both construct, material and optical.
    Invest in excellent product like Kolari is worth the price that I’m not looking back to any cheap filter anymore.

  3. Massimiliano Matera (verified owner)

    Tested for a long time it always works properly and if you follow the suggestion on the website, and you have fitted your camera with a good performer lens you will no longer see flare!
    I am really glad to have purchased this IR720nm gen 3
