Large field-of-view industrial microscope objective (M Plan Apo 20X)
The Wavelength Optoelectronics large field-of-view industrial microscope objective is made of high-quality optical glass and combined with anti-reflection coating technology, significantly improving light transmission efficiency. With a plan apochromatic design, the imaging details are clear and the contrast is high. The objective is designed based on an infinite conjugate optical system, with a parfocal distance of 95mm, and is a brightfield objective for coaxial illumination. For large field-of-view image observation, it supports up to an image-side diameter of 40mm, facilitating the integration of various accessories and adaptation to complex working conditions. It can be widely used in precision metrology and inspection in the semiconductor field as well as high-precision visual analysis and quality monitoring in various industrial scenarios.

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.
