The Grand Cinema™ LUMIS HC 3D-D is a high-end compact 3-chip DLP® home theater 3D dual unit projector system with customizable color filter options for specialist applications. Designed for 3D cinema, the projector may be used in either active or passive 3D mode. The system is equipped with a Mounting Assembly with micro-metric adjustment for precise alignment of the two projectors.

SIM2’s LUMIS HC 3D-D projection system is designed to reproduce 3D images with the same depth and vivid intensity as those experienced at the cinema. Its dual projection format is the result of thorough research into the effects of 3D filtering on projector optical systems. The findings were that such filtering causes light output losses of approximately 60%, when compared to conventional 2D projection.
Clearly a dual-projector system not only allows for accurate calibration of each of the left/right channels, but also enables a higher light output to be realized.
This is important for large screen installations because the light output required to illuminate the screen to the industry standard reference level is much greater than that of a small screen.

The LUMIS HC 3D-D is a revolutionary 3-chip Full HD system based on two LUMIS 3D-S HC projectors. It sports all of the LUMIS 3D-S HC features including
Triple Flash technology, PureMovie, PureMotion, and PureMotion 3D user modes.
The LUMIS HC 3D-D system consists of:
• Two customized LUMIS 3D-S HC projectors with SIM2’s motorized Sliding Filter System inside the optical engine allowing dual projection mode (2D or 3D). The use of this automatic double filter (SFS) allows the use of two different color gamuts on each product.
• Filters (1) included are INFITEC 3D and HDTV (Rec.709). Other filters can be ordered to create a truly customized product (2).
• Projector mounting bracket assembly.
• InstaPort™ Technology.
• SIM2 VISUS active 3D glasses and INFITEC Premium 3D glasses.
• Live Colors Calibration 2.0 Software.

The LUMIS HC 3D-D dual-projector system not only allows for accurate calibration of each of the left/right channels, but also enables a higher light output to be realized. The LUMIS HC 3D-D, when working in 2D dual mode, is able to output up to 6000 ANSI Lumens, with a Full On/Full Off contrast ratio over 22,000:1.

Available in SIM2’s classic high gloss Gun Metal finish.

Technology: Wavelength Multiplex (INFITEC®) 3D systems

The system uses two different INFITEC® filters placed inside two different projectors’ engines between the light source and the DMD, and the same filters placed on the glasses, thus classified as passive.
The filters are very complex with 20 to 30 layers of tint and coatings. They basically act as two slightly different comb filters thus splitting the RGB lamp spectrum and
generating two close sets of primaries, one for the left and one for the right channel.
Each projector displays the corresponding image and the two sets are offset one from the other similar to the way they are in other passive glasses systems. Then, the
images are recombined by the brain through the INFITEC® glasses creating the 3D stereoscopic effect.
Infitec technology has a very low ghosting level.

INFITEC® technology in detail:

Two Infitec optical filters (continue and hatched lines here on the right image) separate the lamp’s optical spectrum in two parts: one for the Left eye and the other for the Right eye.
Each filter is inserted in the optical path of one of the two projectors.The stereoscopic image is obtained by channeling the image for the left eye in a projector and that for the right eye in the other.
The primary colors of the two channels are thus separated by filters and recombined by the viewer using the glasses, also provided with Infitec filters.
