It's been known for some time that most of the more expensive pen manufactures, or the ones who would be inclined to use the term "precious resin" to up sell a plastic pen, have been creating pens with material that is transparent when viewed in the infrared portion of the EM spectrum. And having just gotten my first dedicated IR camera, I just couldn't resist getting some of my more swanky pens out for a nice family portrait. From left to right: Namiki Falcon (SF), Pilot Falcon (SEF), Pelikan M400, Pelikan M405, Pilot Custom (14k), Platinum Century #3776, Pilot Custom 74, Pelikan M800, Pelikan M600, Pelikan 140, Pelikan 400. Here are the pens in the visible spectrum (iPhone 5): http://imagizer.imageshack.us/v2/xq90/823/1n4d.jpg And here are the pens in the near-infrared spectrum (Canon T2i at ≈ 800nm): http://imagizer.imageshack.us/v2/xq90/841/hvkyb.jpg Here's a visual aid: http://imageshack.com/a/img850/1272/dhk.gif Here are the Pelikan M400 and M405: http://imagizer.imageshack.us/v2/xq90/834/pzz6o.jpg And here's the section of the Pelikan 140: http://imagizer.imageshack.us/v2/xq90/853/q4no.jpg The two Falcons and the Pilot Custom are able to be seen through, but just not with the ease of the obvious ones. I only have one Montblanc, a 344, but I can't find it. When I do I'll take a pic and post it here. And I find it very interesting that either the Pelikan M400 or M405 has an opaque rear twist cap…
