Projection Lens
A 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 then precisely project it onto the screen, forming a clear, well-defined 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, and additionally into two major types: fixed-focal-length and zoom.

Telecentric lens （Telecentric）
Imaging Lenses and Objectives
Astarphotonics
Operating Wavelength: 400 – 700nm Optical magnification: 0.5X Working distance: 110mm±3%
Telecentric lenses correct parallax in conventional industrial lenses by maintaining constant magnification over a specified object-distance range, particularly useful when measured objects lie in different planes. This lens combines excellent telecentricity and low distortion with a fixed aperture and lockable focus for stable performance in measurement systems, workshops and assembly lines.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
