Cemented Quadruplet Lens
A four-element cemented lens bonds four lens elements with optical adhesive. Combining refractive indices corrects aberrations/chromatic errors and improves imaging. Four materials/curvatures are arranged and bonded sequentially for complex refraction and better optical performance. Different indices/dispersions focus wavelengths together, reducing chromatic, spherical and coma aberrations for clearer, more accurate images. In camera lenses, classic four-element cemented designs balance large aperture, image quality and imaging range. Industrial inspection uses them to improve spot-illumination uniformity and accuracy. In medicine, four-element cemented interface lenses in stereoscopic endoscopes provide good optics for clear internal observation.
