CIMEX IMPORTED EXCLUSIVELY FOR ITALY
high gain RIGID holographic screens HB: High Brightness,

The HB-FRESNEL-lens screens are screens for rear projection based on optical properties of Fresnel lenses* that capture the image and the focus directly toward the observer by ensuring a wide angle of vision, brilliance, clarity and uniformity of images and avoiding dispersions and hot spots.

The
rear projection HB FRESNEL screen consists of thousands of concentric lenses each of which has a specific and different angles of curvature to capture the light of the projector and forwards it directly to the observer.

The
projector-screen distance may therefore be much smaller than required for traditional holographic screen.


In applications requiring high resolution images as in black control rooms, simulators, conference room, HB FRESNEL rear projection screens ensure exceptional and amazing results!

* Fresnel lenses are "flat" lenses that retain all the focusing features of the traditional lenses' curvature but with minimum size and weight. The result is obtained by cutting the profile of a traditional spherical lens in a series of concentric rings: the curvature is reduced to a flat surface but preserves all the dioptric power of the curvature.
