用内格尔色觉异常镜进行的颜色匹配用于色觉缺陷的鉴别。当在宽范围的视网膜照度上进行这些颜色匹配时，颜色匹配的变化提供了关于再生动力学和中波长和长波长锥色素的吸收光谱的信息。这些稳态颜色匹配随各种条件而变化，并且可能在筛查眼部疾病中具有价值。最近，高亮度LED已经变得可用，这使得我们能够构建基于LED的高亮度异常镜。我们使用廉价，低能量的组件来复制早期的仪器，获得超过5.6 log Trolands的最大视网膜照度。
Color matches made with a Nagel anomaloscope are used in the differentiation of color vision deficiencies. When these color matches are made over a wide range of retinal illuminances, the changes in the color match provide information about the regeneration kinetics and the absorption spectra of the middle- and long-wavelength cone photopigments. These steady-state color matches vary with a variety of conditions, and may have value in screening for eye disease. Recently, high-brightness LEDs have become available that allowed us to construct a LED-based, high-brightness anomaloscope. We used inexpensive, low-energy components to replicate an earlier instrument, getting a maximum retinal illuminance over 5.6 log Trolands.
