LCD Projector Lens Assembly with Prism Block Motor Focus 9x5x4 in

LCD Projector Lens Assembly with Prism Block Motor Focus 9x5x4 in

This is a complete LCD projector lens assembly removed from a projector during service or disassembly. The assembly integrates the projection lens barrel, a dichroic prism block with dual LCD panels, a motorized focus mechanism, and a multi-conductor wiring harness — essentially the full optical and electromechanical light engine core of an LCD projector. The manufacturer and compatible projector model are not identified. Approximate overall dimensions are 9 x 5 x 4 inches.

Applications

LCD projector lens assemblies like this one are the optical heart of LCD-based data and home theater projectors, a technology that became widespread from the early 1990s through the 2000s and continues in use today. In an LCD projector, white light from a lamp passes through dichroic mirrors that split it into red, green, and blue components; each color passes through a dedicated LCD panel that modulates the image, and the three channels are then recombined by the prism block before being focused through the projection lens onto the screen. This type of integrated assembly — combining the prism, LCD panels, focus motor, and lens in one removable module — was common in mid-range and professional LCD projectors from brands such as Epson, Sony, Proxima, Sanyo, Sharp, and Panasonic. It is primarily of interest to technicians repairing or rebuilding LCD projectors, engineers building custom projection systems, or hobbyists sourcing optical components for experimental or display projects.
