AI Technical Summary

Technical Problem

Existing 3D industrial camera lenses suitable for near-ultraviolet light are insufficient to meet the requirements for high resolution.

Method used

An industrial camera lens suitable for near-ultraviolet light was designed, comprising a front optical assembly, a middle optical assembly, and a rear optical assembly. By compressing the incident angle of the off-axis field of view and correcting lens distortion, the lens has a working distance of 155mm to 280mm, an aperture of F2.0 to F2.4, a full-field-of-view distortion of less than 0.15%, and a transmittance of 0.63 to 0.76. The lens consists of seven optical elements, employing specific materials and design parameters to achieve high resolution.

Benefits of technology

It achieves high-resolution near-ultraviolet imaging, effectively meeting high-resolution requirements. It features low lens distortion, high transmittance, and is suitable for high-precision industrial inspection.

Abstract

This application discloses an industrial camera and lens suitable for near-ultraviolet light. The lens includes: a front optical component for compressing the incident angle of the off-axis field of view; a middle optical component for at least correcting lens distortion; and a rear optical component for compressing the incident angle incident on the image plane. The working distance of the lens ranges from 120mm to 260mm; the aperture ranges from F2.0 to F2.4; the full-field-of-view distortion of the lens is less than 0.15%; and the transmittance ranges from 0.63 to 0.76. The advantage of this application is that it provides an industrial camera and lens suitable for near-ultraviolet light that can effectively meet high-resolution requirements.
