测光积分球

积分球一般作为一个理想的漫射光源或匀光器来使用，从而消除由于光源自身特性而造成的出射光束不均匀或者带有偏振方向。积分球之所以有这种特性，主要是由于入射光在积分球内部发生多次漫反射造成的。积分球内表面为

Photometric integrating sphere

Integral sphere is one of the most commonly used measuring instruments in optics. The coating is made of high-quality PTFE material, suitable for UV visible and near-infrared spectra, and has good Lambertian characteristics in this spectral range. The sphere wall has two or more small openings to introduce light or connect photoelectric detectors, and some baffles are designed to prevent the light source from directly shining on the detector, ensuring the uniformity of the test light source. This structure causes multiple diffuse reflections of light before entering the detector, resulting in a very uniform amount of light reaching the detector.

漫反射标准白板

漫反射标准白板白板就是标准白板、参考白板的简称，是一种光学传递标准，是由国家计量院（国家标准局）提供一种已经标定过的、有光谱反射率数据的白板，广大用户要依据这个数据来测量其它样品的光学性能。不管你采用

Diffuse Reflectance Standard Whiteboard

Whiteboard, also known as standard whiteboard or reference whiteboard, is an optical transmission standard provided by the National Institute of Metrology (National Bureau of Standards). It is a calibrated whiteboard with spectral reflectance data that users can use to measure the optical properties of other samples. No matter what instrument or method you use, all measurement data must ultimately be traced back to the standards of the National Institute of Metrology. Only in this way can the measurements of each company be comparable, effective, accurate, and reliable.
