The platen glass is doped with a microwave absorbance metal to provide some protection to the magnetron.
Visible light passes through the Teflon layer and is reflected by the silver layer, so the solar absorbance is low.

To measure absorbance, a wide spectrum light source is needed (that's why OP's spectrometer has tungsten halogen and deuterium arc).
For enhanced absorbance, alternative technologies that come to mind could be electrodeposition with additives that preferentially bind specific crystal faces, nanoimprint lithography+etching.
This is more generally called absorbance[1] and stems from the Beer-Lambert law[2].
Been too long since I've done computer graphics, but you made me think about implementing transparency pass using absorbance instead.
The blindness and self-absorbance in this post is so infuriating I find myself constantly removing personal attacks on you from this comment.

Quote examples
I do not believe your claim is true because "microwave absorbance metal" means the glass will heat up faster than otherwise, which is not what you want.
Belief in or unconscious absorbance of the concept of "manifest destiny" and American exceptionalism seems to run deep in a portion of the American psyche.
Here's my (probably incorrect) thinking: Light passing through the "open state" crystal may travel significantly slower due to interaction/absorbance with the crystal atoms along the beam path.
I was personally involved in developing an electroless deposition technology that created "black gold" that had broadband absorbance across NIR and visible wavelengths.
