使用氚作为光源的微型暗适应计。

Am J Ophthalmol. 1976 Aug;82(2):313-5.

A miniature dark adaptometer to measure monophasic rod function, used with disposable masks, permitted 11 measurements to be taken in 1 1/2 hours. The light source, tritium-phosphoric sulfide gas, had a known brightness decay rate incorporated in the calibration table which is provided with the instrument.

一种用于测量单相视杆细胞功能的微型暗适应计，与一次性口罩配合使用，在1个半小时内可进行11次测量。光源为氚-硫化磷气体，其已知的亮度衰减率已纳入随仪器提供的校准表中。
