Photographic lens
A photographic lens is the core optical component of a photographic imaging system. Its core function is to precisely converge the reflected light from a subject onto the image sensor (CMOS/CCD) through the refraction and focusing of an optical lens group, forming a clear, realistic optical image. It covers all categories such as fixed-focal-length, zoom, wide-angle, and telephoto, and features high resolution, low distortion, wide spectrum, and wide aperture adaptability, meeting the stringent imaging requirements of professional scenarios such as high-end photography, film and television production, and industrial imaging.

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.
