We describe and characterize a straightforward test setup for characterizing temporal and spectral dynamics of photochromic spectacle materials. Three measurement examples of contemporary silicate and organic photochromic spectacles are provided. The setup showed a good absolute accuracy of ≤5% of the luminous transmittance (τ(v)) and repeatability of better than 3%. The samples showed different fading times. The sample with the highest dynamic range was the slowest and showed a noticeable change in the transmission spectra during deactivation. The silicate had the lowest dynamic range but also the most homogeneous transmission spectra throughout activation and deactivation. The proposed test device provided accurate results for spectral and temporal dynamics of photochromic materials under realistic conditions.
我们描述并表征了一种用于表征光致变色眼镜材料的时间和光谱动态的简单测试装置。提供了当代硅酸盐和有机光致变色眼镜的三个测量示例。该装置在发光透射率（τ(v)）方面显示出≤5%的良好绝对精度，重复性优于3%。样品显示出不同的褪色时间。动态范围最高的样品褪色最慢，并且在失活过程中透射光谱有明显变化。硅酸盐的动态范围最低，但在整个激活和失活过程中透射光谱最均匀。所提出的测试装置在实际条件下为光致变色材料的光谱和时间动态提供了准确的结果。
