“PET Crystal” appears across the UST screen market as a way to describe a multilayer optical screen material used with ultra-short-throw projectors. For the NothingProjector Classic, the merchant pairs the PET Crystal material label with a Classic lenticular coating and a 0.6-gain, 160°-viewing specification.
Why the optical structure matters more than the material name alone
The name “PET Crystal” does not tell you everything about performance. The shape and orientation of the light-directing structure, surface treatment, backing, tensioning and frame geometry all affect how a screen behaves. Treat the material name as one part of the specification stack rather than a guarantee of identical performance across different brands.
What the Classic uses PET Crystal to achieve
NothingProjector positions the Classic as a UST-specific ambient-light-rejecting surface. Its structured product spec currently lists 85% ALR, 0.6 gain and 160° viewing. That profile points toward wide seating and contrast support rather than high on-axis gain.
When a higher-gain Fresnel surface may fit better
If you have very strong ambient light and a mostly centered seating arrangement, a Fresnel screen can be worth comparing. The trade-off is typically a narrower viewing cone. That is why “more gain” is not automatically “better” for every room.

Is PET Crystal a universal performance standard?
No. It is a material/marketing category used by screen sellers, not a single standardized cross-brand lab rating.
