Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

This is a set of adhesive-backed thin plastic pieces that one attaches to one’s transport or player disc tray. The disk rests on them during non-spin mode, but presumably don’t touch the applied thin pieces during playback mode. The company says the new Dark Matter pieces reduces background scattered light from reaching the photodetector, thereby improving performance. 

Anyone tried this product? Please specify transport or player if you have and your impressions.

My previous two products, Codename Turquoise and Dark Matter (Emerald Green Liquid that was also very hush hush) absorb visible red and invisible near infrared light, respectively. They have been replaced by New Dark Matter. I also sold a set of various color pens for coloring the CD, including the data side; that product has also been discontinued for obvious reasons.

pop quiz: Turquoise (Cyan) absorbs the visible color red. What color should be used for a Blu Ray player. Free NDM to first correct answer.

There is no doubt that changing the amount of light detected by the sensor can affect the sensor's output.

I'll leave it up to the tweakers so inclined to determine what works best for them.  If Geoff's approach floats their boat, they might want to also consider a teleportation tweak or two, if still available!

Since blu-ray players use 405 nm lasers, lemon yellow should take out the invisible and visible light in that range.

Uh, oh, partial credit alert! 🚨

Yellow will only absorb violet light. Complementary colors only apply to visible colors. That’s kind of the whole problem. There are no complementary colors for invisible light.

See if you can guess what will absorb both the visible violet scattered light and the invisible scattered light in that general vicinity.

Well, some combination of yellow mixed with an organic compound that absorbs UV light bandwidths. There are plenty of organic dyes that absorb in that region (UV). I used to work with them in Advanced Photochemistry Research as an undergraduate.
