FAQ - Supernova Core
Frequently asked questions about dnp Supernova Core
What are the major components of the Supernova Core?
The major components are the optical film, adjustable hooks (to keep the screen flat), the frame and the mounting system.
How is the Supernova Core assembled?
A detailed installation manual is available in the Downloads section.
How is the Supernova Core different than the Supernova One?
The optical properties are the same. The major difference is that the Supernova Core is delivered disassembled and with no supporting back plate to keep the film flat. Instead special rubber O-rings are used to tension the screen material and make the screen flat.
What frame designs are available with the Supernova Core?
The Supernova Core comes in four color options: ‘Black Sand’, ‘Black Velvet’, ‘Silver Alu’ and ‘White Sand’ frames.
What is the difference between Black Sand and Black Velvet frame designs?
The ‘Black Sand’ option is a deep black powder coating with very small sand particles for a good matte low reflection surface. The frame on the ‘Black Velvet’ option is covered with a nice soft black velvet tape for maximum light absorption.
hat are the frame dimensions?
The width of the Supernova Core frame varies with the color options. The ‘Black Sand’ and ‘Black Velvet’ frames are 80 mm [3.1”] wide whereas the ‘Silver Alu’ and ‘White Sand’ frames are 100 mm [3.9”] wide. The extra 20 mm [0.8”] on the silver and white frames is due to an additional inner black velvet masking frame to avoid reflection in case of projector overscanning.
Is the Supernova Core available in custom sizes?
Yes. We can make custom sizes up to 1.5 m [60”] image height. There is an extra charge for custom sizes. See the product specifications in the Downloads section for available sizes.
What is the recommended projection distance?
The recommended minimum lens throw ratio (LTR) varies with the screen material. In general we recommend not going closer than 1.5:1 with the projector at the top of the image in order to avoid the bottom of the picture becoming darker than the top. That means a projection distance of minimum 1.5 times the image width. For the Supernova 23-23 screen material we recommend to go out to 1.8:1 LTR in order to reduce hot-spotting. In general the longer the projection distance, the better. Closer positions can result in un-uniformity.
Can the Supernova Core be used as a whiteboard?
Because of the flexibility of the screen, we do NOT recommend writing on it. The applied pressure of writing could permanently damage the screen by making indentations.
