PROBLEM TO BE SOLVED: To provide an instrument and a method for measuring internal quantum efficiency, capable of accurately measuring the internal quantum efficiency. SOLUTION: A light-receiving element 15 receives a minute solid-angle dωof the light pulse output from a measuring device 1. A lock-in amplifier 16 detects accurate photoreceived quantity P(W) of the photoreception element 15. A measuring instrument 17 measures the internal quantum efficiencyη<SB>int</SB>of the measuring device 1, by using the photoreception quantity P detected by the lock-in amplifier 16 and light extraction efficiency T. The light pulse, received by the photoreception element 15, is the minute small solid-angle dωof light pulse output from the measuring device 1 therein. The light extraction efficiency T is thereby calculated, only with the Fresnel reflection amount of the measuring device 1. COPYRIGHT: (C)2008,JPO&INPIT
