Plano-Convex Lens
A plano-convex lens images by refraction through one flat and one convex face, forming real/virtual images according to object distance u and focal length f. The convex face is the main refracting surface: parallel rays bend toward the axis/focus; entry through the flat face gives weaker refraction but still follows refraction laws. For u>f, inverted real images form: reduced at u>2f, equal-size at u=2f and enlarged at f<u<2f, as in cameras/projectors. Real rays converge and can be captured on a screen. For u<f, a magnified upright virtual image forms at backward ray extensions and cannot be screened, as in magnifiers. At u=f, output is parallel and no image forms. The source states plano-convex lenses have greater aberration, such as spherical aberration, than biconvex lenses and commonly collimate/focus parallel light, while biconvex types serve complex imaging. 南京领英创光电科技有限公司 offers customization and welcomes inquiries.
