【Abstract】 This paper presents a new device for measuring the veiling glare index of long focal lengthoptical system. The device can make the precise measurements of veiling glare index at an extra-axialobject point and analyze the influence of each stray light source on the veiling glare index as well asavoiding making the large diameter integrating sphere.更多还原
