The transmission spectrum of the lens is essential to calculate irradiance at the surface of the retina. Although the mouse is a common model for ophthalmic research, there is little information on the transmission of the mouse lens. Attenuation by the lens is partly dependent on lens thickness; however, the attenuation coefficient is independent of lens thickness. In this study, we measured the attenuation coefficients of the albino and pigmented mouse lens as well as those of the rat, pig, and human lenses, and provide a composite equation that describes the attenuation coefficients in the ultraviolet and visible bandwidths (360-700 nm). In the near infrared region (700-1020 nm), water absorption must be included to explain the measurements.
晶状体的透射光谱对于计算视网膜表面的辐照度至关重要。尽管小鼠是眼科研究的常用模型，但关于小鼠晶状体透射的信息却很少。晶状体的衰减部分取决于晶状体厚度；然而，衰减系数与晶状体厚度无关。在本研究中，我们测量了白化小鼠和有色小鼠晶状体以及大鼠、猪和人类晶状体的衰减系数，并提供了一个复合方程，该方程描述了紫外和可见光带宽（360 - 700 nm）内的衰减系数。在近红外区域（700 - 1020 nm），必须考虑水吸收来解释测量结果。
