A couple of questions here. First those laser-reflective coatings on modern armored vision blocks modelers are representing, what colors are there. I’ve seen them in blue and magenta but was wondering what other colors are there. Second what US modern armor are using them, is the Stryker using them, and when did they start installing them onto the armored vehicles.

Thanks,
Joe

Joe, the laser protected vision blocks have been around for years. I can think back 10-12 years ago and remember seeing them. As to colors, they can run the gamut. Mostly I've seen the pinks, purples, greens and blues. It all depends on the angle that you are standing at when viewing the vehicle. More than likely they are installed on the Stryker. Hope this helps, "Q"

The color would depend on the type of laser(s) to be defeated.

As you can see in this chart laser intensity is rapidly changing along with the lasing material / method in which the color(s) depends.

Here is a translation of those colors- http://en.wikipedia.org/wiki/Color
As the technology is applied the spectum coverage required for optical safety grows at rate that is difficult to keep up with and impossible to stay ahead of due to the corresponding advances in intensity. This accounts for the change and variety of color used.

The change in color you see in the same block is a refraction of that wavelengths reflection and is dependant on the light source, its angle of incidence and the material(s) in the block. Similar to all the changing colors you see in a compact disk.

I think you have found another obsessive rivet counters delight.
