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.

Semiconductor manufacturing field; in this field, Wavelength microscope objectives are mainly used for defect analysis, failure localization and process monitoring.; Defect detection and classification: identify and classify particles, scratches, crystal defects, etc. on wafer surfaces. High resolution and absence of color artifacts ensure accurate identification of defect features.; Failure analysis: locate short-circuit and open-circuit points in faulty chips. The plan characteristic makes the edges as clear as the center when searching for abnormal regions within an ultra-large field of view.; Critical dimension measurement: perform sub-micron accurate measurement of line widths, apertures, etc. of integrated circuits. Excellent image quality is the basis for measurement accuracy.; Industrial inspection field; in the industrial field, Wavelength microscope objectives are used for material analysis, quality control and non-destructive testing.; Materials science: analyze the grain structure, phase composition and defects of metals, ceramics and polymer materials. Apochromatic correction is crucial for observing anisotropic materials under polarized light.; Precision manufacturing: inspect the wear, microcracks and surface roughness of precision components (such as cutting tools and bearings). High resolution can reveal early signs of failure.; Electronics industry: inspect the solder joint quality and circuit integrity of PCB boards. The plan objective facilitates automatic scanning and measurement of the entire circuit board.
Brightfield microscope objective: designed specifically for coaxial illumination brightfield imaging, using a plan apochromatic optical structure, with high imaging contrast and large field-of-view observation capability, supporting an image-side diameter of up to 40mm. Darkfield microscope objective: suitable for observing scattering and unevenness on surfaces, using a plan apochromatic optical structure, with high imaging contrast and large field-of-view observation capability, supporting an image-side diameter of up to 40mm. White light interference microscope objective: used for non-contact measurement of surface topography and geometric features, using a plan apochromatic optical structure, with large field-of-view observation capability, supporting an image-side diameter of up to 40mm.
