2.2.2 Optical Engine

The Optical Engine consists of the Lamp Unit, the Light Guide Unit, the POP (Panel-on-

Prism) Unit, and the projection lens.

Component 

Name

Function/Other

Lamp Unit

An UHE-170W high-intensity discharge lamp is used as the light source.

Light Guide 
Unit

 In addition, a UV filter protects the LCDs from harmful ultraviolet light. After this light is 
polarized, it is then split into 3 spectrums (R, G and B).
Multi Lens Alley
(EMP-822 only)

Diffuses the light from the lamp to provide uniform illumination.

Polarizer (PBS)

Polarizes the light and remove the U/V component harmful to the 
L/V.

Dichroic Mirrors 

Disperse the polarized light into the R/G/B spectrums.

POP Unit

The heart of the Optical Engine. Consists of the L/V (R/G/B) and the Prism Unit.

Light Valve (L/V)

Controls the intensity of the distributed components of the RGB 
light. 

Prism Unit

Integrates the RGB light

Projection 
lens

Sends the integrated light onto the screen. Two adjustment rings are mounted: the Zoom 
Ring to scale the projected image, and the Focus Ring to focus the lens.
