Large images from a short distance with the Full HD laser projector
The optical system of this model enables a large-format image to be projected from a short distance of, for example, less than one metre. In conference rooms or classrooms where presenters stand close to the projection screen, this short throw projector reliably prevents people from casting long shadows on the presentation. Furthermore, the presenter is not dazzled by the light beam, which makes working significantly more comfortable. At the same time, the native Full HD resolution ensures that detailed Excel spreadsheets, text and graphics remain legible for all participants in the room, right down to the furthest corners. This allows you to conduct professional meetings and lessons without any visual limitations.
Reliable DuraCore laser technology for continuous use
In everyday business or during continuous use at exhibitions, reliability and running costs play a central role. This maintenance-free projector relies on a highly advanced laser light source, which eliminates the need for traditional and costly lamp replacements. Coupled with IP6Xcertification against dust ingress, image brightness remains stable throughout the entire lifespan of up to 30,000 hours. This saves on operating costs in the long term and protects against unexpected failures during important meetings. Thanks to a housing design that is up to 34% more compact than older generations of devices, the white chassis also blends discreetly and unobtrusively into any room décor.
Maximum flexibility with the versatile short throw projector
Modern spaces demand flexible installation options that go far beyond traditional ceiling mounting. Thanks to support for 360-degree and portrait projections, the device can be installed at any desired angle. Whether for vertical advertising displays in retail, floor projections in museums or angled ceiling mounts in historic buildings. The integrated vertical and horizontal keystone correction of 15 degrees each compensates for distortion in an instant, should the projector ever fail to be aligned perfectly at right angles to the wall. The result is a perfectly proportioned image in almost any conceivable environment.
