介绍了一种可用于瞄具、望远镜、透镜等光学系统的新型透过率检测系统。系统集光谱技术、检测与转换技术、计算机技术等多种技术于一体,分别设计了白光和光谱光源准直扩束系统和双通道反射测量光路。可进行宽光谱范围和大口径透过率检测。同时保证系统减小杂光、背景光和光源波动引起的误差。光谱范围覆盖可见—近红外波段(300~1600 nm),测量光束直径可达60 mm,分别使用4种透过率的标准透过率板进行标定实验,得到绝对测量误差≤0.5%的实验结果。
A new transmittance detection system for optical systems such as sights, binoculars and lenses is introduced. The system integrates spectroscopy, detection and conversion technology, computer technology and other technologies into one. The white light and spectral light source are respectively designed to extend the beam expander system and dual-channel reflection measurement light path. Can be a wide range of spectral and large-aperture transmittance detection. At the same time to ensure that the system to reduce stray light, background light and light source caused by fluctuations in error. The spectral range covers the visible-near-infrared (300 ~ 1600 nm) and the measured beam diameter up to 60 mm. Calibration experiments were carried out using four transmissivity standard transmissivity plates, respectively. Experimental results with absolute measurement error ≤0.5% were obtained .
