Design of Optical System for Eccentric Photography Sight Detecting Device
To achieve the purpose of reducing errors in the measurement of the refraction of the human eye by eccentric photographic optometry and to produce clearer photographs of the human eyes, the imaging system of the device was designed. The working distance of the lens is 1000 mm, the focal length of the system is 46.7 mm, the total length is 51.4554 mm, and the F-number is 2.8. After optimization, the maximum optical system distortion is not greater than 0.3%, and the spherical aberration, field curvature, and distortion are well corrected. The imaging lens has the characteristics of simple, compact, and fine quality, which accords the demand of eccentric photographic optometry equipment.
