Projectors

• Standard office projector

  

  Brightness:

  when used as a light source, a conventional mercury lamp produces 3000-3500 lumens of light

• Desktop office projector

  

  Brightness:

  4000-5000 lumens

  Use:

  suitable for spaces larger than classrooms and meeting rooms

  Peculiarities:

  the increase in size occurs solely due to an increase in brightness

• Entry-level installation projectors

  

  Peculiarities:

  dimensional models, usually based on a laser light source, which are assembled with increased requirements for reliability and taking into account the possibility of continuous use. Depending on the model, such projectors have removable lenses, which allows you to select optics for the required projection distance. Larger housing sizes make the cooling system quieter.

• Installation projectors

  

  Brightness:

  from 7,000 lumens to 60,000 lumens

  Operating mode:

  24/7

  Peculiarities:

  stitching of several images is possible, advanced options for adjusting images when projecting onto curved surfaces, convenient to mount with an inclination in any direction

• Short throw and ultra short throw projectors

  

  Distance to width ratio:

  short throw - 1:1 or less, ultra short throw - from 0.5:1 to 0.1:1

  Peculiarities:

  makes it possible to place the projector in front of the audience, expanding a large image

• 3D projectors

  

  Peculiarities:

  for museums, digital advertising and mapping, passive 3D systems based on polarization technology are usually used. In this case, two images are created with different polarizations of light. Thus, the projector must be able to separate the light streams to provide different polarization - this is done using special complex lens attachments, or by pairing (stacking) two projectors.
