Objective Introduction
Wavelength Opto-Electronic’s large-field industrial microscope objectives are manufactured with high-quality optical glass and anti-reflection coatings, significantly improving light throughput. The plan apochromatic design delivers crisp imaging details and high contrast. Built on an infinity-corrected optical system with a parfocal distance of 95 mm, these objectives are designed for brightfield coaxial illumination. They enable large-field observation, supporting an image circle diameter up to 40 mm, facilitating integration with various accessories and adaptation to complex working conditions. They are widely used in precision metrology and inspection in the semiconductor industry, as well as high-precision visual analysis and quality monitoring across diverse industrial applications.
