Bi-Telecentric Lenses
Object & image side bi-telecentric lenses, constant magnification, zero perspective error, for ultra-precise workpiece size measurement.
ANDA bi-telecentric lenses adopt object-side and image-side double telecentric optical design. The magnification remains constant even if the workpiece has slight position fluctuation, completely removing perspective distortion. With ultra-low distortion and high image uniformity, this series is the preferred optical solution for high-precision dimensional measurement in SMT and semiconductor industries.
