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.
