双侧远心镜头系列 Double-side Telecentric lens
双侧远心镜头广泛应用于精密测量、检测及工业自动化等领域，由于其在景深范围内无视差、放大倍率不变的特性，可为测量提供更高的精度。
Double-side Telecentric lens is widely used in the field of Metrology,Gauging and industrial automation.This series Telecentric lenses correct perspective erroes that yield variations in magnification through the DOF and present more accuracy than conventional fixed focal length lenses
▶双远心设计 (Double-telecentric design)
▶高分辨率支持百万像素CCD (High resolution and support million pixels CCD)
▶高光通量（F5） (High Light Throughput (F5))
▶低畸变提供更高的测量精度 (Low distortion and providing higher accurate of measure)
