Background scattered laser light

The Green Pen works quite well, at least it's audible. But green only affects the visible red portion of the scattered laser light. And I had a product that absorbed invisible infrared light, which represents most of the laser's spectrum, the nominal wavelength being 780 nm. I had it up until this week when a new Dark Matter came along that does both - absorbs red and infrared scattered light. It kills two birds with one stone.

I have the origional dark matter and it works well.

New Dark Matter is a set of thin adhesive squares that are applied to the tray.

Will this impact the rainbow colors (think that's right) that i have in the tray right now? I bought the tray colors a few years ago from you.

The new Dark Matter will not impact previous coloring. But the new Dark Matter is a general solution for all visible and invisible light so can be used for CD, DVD, SACD and Blu Ray. CD is the only format with an infrared laser.

Your site links to the Intelligent chip when you click the new dark matter link. I'm interested. I have a code name turqoise now.

Everything you need to know about NDM is on my home page.

 

The scattered light that is greater in power than 75% of the real reflected signal ..., posted on April 2, 2021 at 04:17:50
Is determined by the photodetector to be the real signal. Another interesting tidbit is that I recall from the book on optics written by the head of IBM Optical Lab some 15 years ago is that every improvement you can make in the "analog" laser reading process is multiplied downstream.
