By combining a laser, a fluorescent element and an LED, Casio has created an original mercury-free hybrid light source* capable of generating high brightness. Casio has achieved high brightness output of green light, which until now was considered difficult with conventional semiconductor light sources, by efficiently converting blue laser light into green light using a fluorescent element.

*The Slim Hybrid Light Source can only be replaced by the Casio Factory Service Center. Disassembly of the projector and/or use of its technology or components for other purposes is potentially dangerous and strictly prohibited.


Provides 10X longer light source life than Casio mercury lamp while being more economical based on lamp replacement. The Slim projector features quick startup and shutdown. The projector reaches its maximum brightness in a minimum of 8 seconds and requires no cooling down period - an advantage for keeping presentations focused and smooth.


The Slim projector delivers a 50 percent increase in color spectrum for high impact presentations due to improvements in LED and laser technology. Superior color reproduction enhances color purity allowing visual effects to appear brighter and offering powerful images that conventional projectors cannot match.


Compared with conventional high-brightness projectors employing mercury lamps, Slim technology cuts costs as well as the time and effort involved in lamp exchange while maintain clear, high-quality images over an extended period. The lamp free design is backed by a comprehensive 3-year warranty including the light source; users can expect reliable worry free operation from the Slim projectors.


The native WXGA (1280 X 800) resolution of the Slim projector allows for optimal viewing of content created and formatted for today’s widescreen displays. Whether it is viewing a spreadsheet or two applications side by side, the WXGA Slim projector provides more useable screen area and displays more information on the same screen. Widescreen display formats have become the standard and now your projector can match the widescreen display of Notebook PC’s and HD Video sources.


Whether you are in a small office or a large boardroom the 2X power zoom lens gives you the flexibility to easily position the projector.


The Automatic Brightness Adjustment, which adjusts lumen output based on the level of ambient light in the room, saves power, which saves money (and saves you from eye strain as well.)


A built-in HDMI input provides a direct digital input and allows connectivity with many Widescreen Notebooks now shipping with HDMI outputs. Compatible with HD Video formats, HD Video sources including Blu-Ray players, cable converter boxes and gaming systems can be connected to the Slim projector.
