AR Coating
What is the AR coating and what does it do? The AR coating option adds an IR centered anti-reflective coating onto the IR filter we install when we perform an infrared conversion. It reduces hotspot artifacts that some lenses are prone to, and can reduce other stray reflections. On our full spectrum conversions we apply a broadband AR coating that covers the UV, visible, and IR ranges. The coating does not reduce optical performance in any way and is highly recommended.
Background:
Uncoated glass has a reflection of around 4-5% at all wavelengths, and we found that this reflection off the sensor filter was bouncing off the glass and reflecting back from the lens housing and aperture blades to cause IR hotspots. We developed this anti-reflective coating that is centered around the IR wavelengths that cause hotspots, and reduced the 5% reflection down to <0.5%
Conversion AR Coating
When applied to our internal conversion filters, we find that hotspots are significantly reduced during infrared photography. Below is a sample from a Nikon 50mm 1.8 which has a strong hotspot at small apertures. Independent tests also available from Mark Hilliard here and Edd Noble here.

Bartosz –
I have bought the 665nm filter for DIY conversion of my 20D. Package arrived quickly – and I live in europe 🙂
I have performed the conversion by myself and thanks to great fitment of the filter it turned out to be pretty easy and conversion was a success. Thanks to the exact thickness of the new filter i did not have any problems with AF after conversion. Thanks KolariVision!
