The projection lens is the "image magnification core" of a projection system. Its core function is to magnify the tiny pixel array on the image source through optical refraction and precisely project it onto the screen, forming a clear and regular large-size image. Projection lenses can be divided by throw ratio into four major categories: ultra-short throw, short throw, medium-long throw, and long throw, plus two major types: fixed focus and zoom.

Overview

The projection lens is the "image magnification core" of a projection system. Its core function is to magnify the tiny pixel array on the image source through optical refraction and precisely project it onto the screen, forming a clear and regular large-size image. Projection lenses can be divided by throw ratio into four major categories: ultra-short throw, short throw, medium-long throw, and long throw, plus two major types: fixed focus and zoom.

Applications

Home projection, business meetings, cinema projection, laser TV

Key Features

The optical path is reversible with a photographic lens; generally a fixed aperture (maximizing output illuminance), mostly fixed focal length lenses, with a zoom ratio covering 1.5-5 times; engineering-grade products can achieve higher zoom ratios; the lens aperture is strongly related to product positioning, throw ratio, and aperture parameters. Under the same specifications, the clear aperture of a projection lens is generally larger than that of a consumer camera lens; classified by throw ratio into ultra-short-throw, short-throw, medium-throw, and long-throw lenses, which can adapt to different projection distances and image size requirements.
