2.1 Introduction

The assemblies and components in the Model 200 projector are contained mainly in the five sections below:

•The Optics Assembly Section is located at the front area of the projector. The Optics Assembly Section includes the Condensing Lens, Cold Mirror/IR Filter (

CAUTION!: The term "cold mirror" is used because the mirror passes infrared light and its reflection contains only "cold' light that does not transmit appreciable heat. As a result of the absorption of infrared heat radiation, "cold" mirrors can get very hot.), Ultraviolet Filter, Dichroic Mirror Assembly, Prisms, Combining Prism, Image Mirrors, and the Zoom Projection Lens.

•The Arc Lamp Assembly section is located in the right front area of the unit. It contains the Ignitor, Laser Power Supply, Xenon Arc Lamp and Elliptical Reflector.
