A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.

Innovations in Optics' projectors achieve spatially uniform illumination fields by combining our patented COB LED technology and efficient, non-imaging, homogenizing optics with precision re-imaging lens systems.

Excellent projection quality is the result of the symbiosis of the best chip technology and outstanding projection optics. ZEISS VELVET SIM LED projectors are equipped with high-performance lenses from the ZEISS DIGIGON series to complete their image.

We present a new optical system design for a projector with a single digital micromirror device (Texas Instruments Digital Micromirror Device) that improves on previous designs in terms of optical efficiency, uniformity, and contrast while yielding a low-profile and compact system.

How much should the average installer know about projection optics, beyond specifying a certain focal length for a specific projection throw and image size? The answer is simple, the more you understand how the projector’s lens affects the quality of the projected image, the better you will be at choosing the right projector.

2024年5月28日 · Discover the essentials of projector optics, including clarity, brightness, and resolution. Learn how these factors enhance your viewing experience. Projectors have become indispensable tools in various settings, from classrooms and conference rooms to home theaters and outdoor cinemas.

Optical systems for single-panel projection applications can be grouped into two main architectures by describing the conditions at the device. Each type has unique advantages or disadvantages that determine suitability for a given application, depending on the most critical performance parameters for that application.

When you buy a camera, you want to know what kind of lens it has and what kinds of lenses you can get to enhance your picture-taking ability. With today's projectors, Zoom lenses are pretty standard. The important question is how much a lens's f-number — the smaller the number, the more light - changes at different zoom settings.

Single chip DLP LED projectors are capable of producing 3000-5000 lumens depending on the DMD (Digital Micromirror Device) and LED illumination design. There are several significant advantages of a projector system with LED illumination.
