Introducing the new C3X LUMIS 3D System

3D stereoscopic imaging is used in many industries, such us Film and Entertainment, VR Simulators, 3D Gaming, Medical Imaging and many others professional applications to improve the understanding of complex objects, in order to shorten the decision process and to increase the efficiencies of the projects.
Apart from professional use of 3D stereoscopic technology 3D is now becoming widely adopted in consumer and large venue market for educational and entertainment purposes.
For all these markets, SIM2 offers a new high quality end high efficiency solution: the new C3X LUMIS 3D system.
First of all let’s analyse what 3D stereoscopy means and the technologies used to represent 3D images.

3D Stereoscopy

The 3D stereoscopy principle is simple. Two images, each with a slightly different viewpoint, are projected onto a screen, and presented to each eye individually.
The human brain interprets them as if they were a single image, allowing the user to experience depth by combining the result of the images in a three dimensional picture.
All stereoscopic displays show left and right views encoded together on a 2D screen and rely on a decoding system, commonly a pair of glasses, to filter them into each eye. They will only differ in the encoding and decoding domain they use. It can be in the color spectrum (anaglyph and INFITEC®), in time (active glasses with digital light processing [DLP] 3DTV and 3D projectors), in polarization (RealD, Dual projectors).

Anaglyphic encoding

Anaglyphic encoding is used to provide a stereoscopic 3D effect employing one of a pair of complementary color filters for each eye (usually red and cyan). The two parallel images, shot with a stereoscopic camera, during the printing process are superimposed on the same support (film frame) through two additive filters, one red and one cyan. Glasses with complementary colored filters discriminate the appropriate images.
The brain fuses the two images giving the viewer the perception of a three dimensional scene.
Anaglyphic encoding is prevalent in cheap depth displays technologies and gets its bad reputation from a series of side effects. Basic color encoding schemes have two major limitations. They cannot reproduce the whole color spectrum, and they have a low separation power, which means there is a fair amount of color leakage from one eye to the other. Thus, it’s suitable for applications that do not require a perfect color rendering.

Active glasses systems

Technically they are liquid crystal shutters (or LCS) which blind the left and right eye in synch with a display that shows the left and right images alternately. The faster the better, because each eye sees only one image over two displayed on the screen. They have infrared (IR) sensors that allow them to sync wirelessly to the display system.
The display alternates between two sets of the same image, one for the left and the other for the right eye. The two sets are offset one from the other similarly to the way they are in passive glasses systems. But the two sets aren't shown at the same time, they turn on and off at a high-speed rate. In fact, if you were to look at the screen without wearing the glasses, it would appear as if there were two sets of images at the same time. The display must display the image at 120Hz, otherwise you’ll see a very irritating flicker.
Active glasses needs batteries replacement.

RealD (polarizing) systems

RealD system uses an active circular polarizer placed just in front of the projection lens, synchronized with the projected left and right image.
The system requires a silver screen to maintain the polarization of the light and disposable polarized passive glasses with a very slight green tint. Because of its high crossover ratio, Real-D requires a ghost busting pre-processing that makes its deliverables incompatible with other systems. It’s highly diffused on Cinemas for the cheap price of the glasses.

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.

Why SIM2 has chosen INFITEC® technology?

Infitec Wavelenght Multiplex Imaging is a passive 3D stereo visualization technology adopted successfully for professional digital cinema and simulations applications. Coupled with SIM2 projection technologies it results in one of the most advanced, reliable and outperforming solution.
Infitec also means that stereo separation is independent from viewing angles allowing different home and professional applications such as moving simulators or immersive environments where standard polarised 3d technologies are not viable.


- By using screens with gain = 1, stereo images are rendered fully homogenous. No hot spots.
- Channel separation is definitely superior compared to Polarizer technology that means no ghost effect and no need of extra custom processing between 2D and 3D.
- Exceptionally clear and bright images achieved by means of high quality quartz glass filters in the projectors and 3D glasses.
- INFITEC® works with the best in DLP™: 3-chip. The same technology selected by Dolby for its Digital Cinemas


- There’s no need of special Silver Screens. You just project on your standard screen, without swapping from 2D to 3D screens: very easy set up.
- Easy and precise adjustment of dual projector stereo images thanks to the custom stacking bracket system.
- Suitable for Rear Projection Applications
- No need of extra 120Hz processing: you can watch 3D with your current set up.

Cost Efficiency

- Infitec stereo imaging works efficiently on all white screens. No need for special and expensive silver screens. Moreover, large image sizes do not incur the high extra costs associated with cumbersome special silver screens.
- Filters in the INFITEC® 3D glasses are passive elements that consume no power. Maintenance is not required for the INFITEC® 3D glasses.
- INFITEC® 3D glasses contain stable glass lenses that are resistant to any standard cleaning procedure. No aging by repeated cleaning.
- INFITEC® works with most used, cost effective and efficient UHP™ lamps

C3X LUMIS 3D Solution

SIM2 offers a passive 3D stereo projection solution for large screen size installations. The system is designed to work in dedicated pairs because each projector of the pair has built-in a special INFITEC® filter which is necessary different to the other to assure the 3D visualization. The totally new SIM2’s motorized Sliding Filter System (SFS) enables to remove the Infitec filter from the light path in few seconds providing very flexible swap among 2D and 3D images.

The C3X LUMIS 3D system is composed by:
• two dedicated C3X LUMIS projectors with SIM2’s motorized Sliding Filter System inside the optical engine allowing dual projection mode (2D or 3D). Filters included are Infitec and HDTV (Rec.709), but DCI filter is also available upon request.
• customized stacking bracket with micrometric adjustment capability
• Infitec Premium glasses (2 pairs)
• EasyCinema PC-based Color Calibration Software

Each C3X LUMIS composing the 3D system is not a common one. Apart from the SFS system described above, in order to compensate the typical light output reduction due to the Infitec filter absorption (around 40-45%), both projectors are equipped with PRO lenses without contrast masks. Thus, when working in 2D dual mode the system is able to output up to 7000 ANSI Lumens maintaining a high full On/Full Off contrast ratio over 12,000:1.

SIM2’s C3X LUMIS 3D System advantages:

• dual C3X LUMIS image quality
• Passive technology avoids the use of external active components like the powered glasses which has to be synced with the image content to switch over from Right to Left eye by an external IR transmitter.
• Each frame dedicated to the left and to the right eye are displayed at the same time. This allows higher “information density” going to the viewer.
• Color accuracy: thanks to the special Calibration Software provided we can create bigger color gamut respect a single projection system
• Modularity and Redundancy. 2D single, 2D dual and 3D visualizations are possible simply by pressing a button on the remote control and if something happens to a projector the customer can always enjoy the picture quality of the second one
• No special and expensive screen needed
