The B&W 55mm Infrared Dark Red (092 = 89B) Filter is nearly opaque. It looks dark purplish/red when held in front of a light source and blocks visible light up to 650nm. It passes only 50% of the radiation just below 700nm (thus the dark red color).

Comments about B+W 55mm Infrared Dark Red 092 Glass Filter:
In the world of photography 99% of what is going on is in the catagory of digital. I have opportunity to take advantage of many people who are just now switching from film to digital.
As I learn about the "infra-red" computer software feature in Photoshop Elements Vr. #9 and the "infra-red" lens filter that I bought from B&H I can learn the difference between popular trends in the business and truly skilled photography.

Comments about B+W 55mm Infrared Dark Red 092 Glass Filter:
This filter interferes with the attachment of the lens hood for my Leica 21mm f/2.8 Elmarit-M Asph, in fact no 55mm B+W filters allow the hood to attach. Otherwise, it's perfect: the glass is flat on both sides and the mount screws into the front of the lens.

I use it with a tamron 90 mm sp macro and my pentax ist dl. Since my camera is not a infrared camera I could just use the filter as a dark red one. It is good quality.
