Overview
The engine unit consists of the following parts:
Image 2-1
• light pipe — makes the light beam homogeneous and sets the correct aspect ratio to the light beam
• prism and formatters — the prism splits up the homogeneous white light into red, green and blue light beams and directs them
to the DMD’s. Next, this prism merges the processed light beams into one full color video image, which is projected via the
projector lens onto the screen
• cooling circuit — keeps the temperature of the engine within its limits
