Reflectance spectrophotometry is the most established and widely used objective technique for the assessment of port-wine stain (PWS) skin, and has been applied extensively in other dermatological applications. To date, no review has been published regarding the different spectrophotometric devices used on PWS skin. This paper comprises such a review, introducing the reader to the relevant background material and then discussing scanning, narrow-band and tristimulus spectrophotometers in turn. Scanning spectrophotometry is the most versatile of the three methods but it is noted that considerable expertise is required to interpret the acquired data. Narrow-band and tristimulus devices are available at a much lower price and can be considerably simpler to use. They do, however, provide limited information that does not account for the complex effects of melanin and other chromophores within the skin. Although scanning spectrophotometers would be the preferred choice for most investigations, cheaper, simpler and equally reliable options are available and may better suit the needs of some research projects.
反射分光光度法是评估葡萄酒色斑（PWS）皮肤最成熟和广泛使用的客观技术，并且已经广泛应用于其他皮肤科应用中。迄今为止，尚未有关于用于 PWS 皮肤的不同分光光度设备的综述发表。本文就包含了这样的综述，向读者介绍了相关的背景材料，然后依次讨论了扫描分光光度计、窄带分光光度计和三刺激分光光度计。扫描分光光度法是这三种方法中最通用的，但需要注意的是，解释所获得的数据需要相当的专业知识。窄带和三刺激设备的价格要低得多，并且使用起来可能要简单得多。然而，它们提供的信息有限，无法解释皮肤内黑色素和其他色团的复杂影响。尽管扫描分光光度计将是大多数研究的首选，但也有更便宜、更简单且同样可靠的选择，并且可能更适合某些研究项目的需求。
