This product does not emit light of its own, so the standard review format will not be used and the product will not be assigned a rating. This website is mostly about light-emitting products, but occasionally, you'll see non-light emitting products on it too if it's something I really like or use.

This is the "sample" pack of Roscolux optical filters; though these filters are made for photographic use, I purchased them specifically to use with high-powered lasers so that I could attenuate (dim/decrease the intensity of) the main beam so that I could shoot video of the lasers destroying other things without having the laser radiation so overwhelm the CCD in my camera that you could not see the destruction or other "mischief and mayhem" that the laser was causing.

***VERY IMPORTANT!!! These filters DO NOT block the 808nm and 1064nm NIR laser lines from the pump diode & KTP crystal in a DPSS laser!!! You must therefore not use them in place of the IR filter in such a laser -- you are risking serious and possibly permanent eye injury if you do!!!

SIZE

I believe that these filters are designed to be removed from the book and used over your camera's speedlight (xenon photoflash); though I have yet to figure out how to do that without causing breakage.

Each filter comes with a same-sized sheet that tells you the filter's name & number, the light transmittance value (as a percentage), and has a spectral response graph -- though I do not know what light source this is based upon.

For the spectrographic analyses on this web page, I used a SureFire M2 Millennium Centurion incandescent flashlight with a P61 lamp assembly as the light source, and set things up so that the filter was held rather squarely against the face of the spectrometer's light input aperture to eliminate any stray radiation from the light source itself -- that is, only filtered light was allowed to reach the spectrometer's detector assembly.

Control spectrum (incandescent SureFire M2 Millennium Centurion with a P61 lamp assembly).

This spectrum was taken with NO filters between the flashlight's
bulb and the spectrometer's light input aperture!!!

Spectrographic analysis of the M2 shone through the #4660 CalColor 60 Red filter.

Spectrographic analysis of the M2 shone through the #4690 CalColor 90 Red filter.

Spectrographic analysis of the M2 shone through the #4460 CalColor 60 Green filter.

Spectrographic analysis of the M2 shone through the #4490 CalColor 90 Green filter.

Spectrographic analysis of the M2 shone through the #4260 CalColor 60 Blue filter.

Spectrographic analysis of the M2 shone through the #4290 CalColor 90 Blue filter.

TEST NOTES:
This Roscolux Swatch Book was purchased from a now-unknown vendor (possibly Amazon.com) in late-June 2007, and was received on 07-02-07.

It is not known where this product was manufactured.
A product's country of origin really does matter to some people, which is why I wanted to publish it on this web page.
