Holoprojector

Types and brands of holoprojectors.

Epsilon type 8 projector: Small projector built for stationary visual projections no larger than 2 cubic metres. The projector itself is the shape of a small cube and may be hidden within the projection. Though this projector has the capacity to create solid projections, the device is known to short out when pushed to its limits. It's commonly used to display statistical information to personnel giving a presentation, briefing, or if someone forgot their PADD.
Vaicor type 3 projector: Small projector built for stationary holoprojections no larger than 3 cubic metres. The projector itself is a small rectangular prism, and may be hidden within the projection. This projector is commonly used to project tables and chairs in lieu of real ones.

Epsilon projectors: A line of holoprojectors designed by former Starfleet engineer Yanri and his team in the late 2380s after branching away from specialist tricorders. The team's projectors are known more for reliability at displaying information.
Vaicor holoprojectors: A line of holoprojectors by Dr. Matthal Vaicor, an expert in holographic components, in the late 2380s. These projectors are known for structural reliability.
