Abstract
A solid immersion lens holderA is provided with a base partattached to an objective lens, and a lens holding partprovided with the base part, extending in a direction of optical axis L of the objective lens, and arranged to hold a solid immersion lensat an end portion thereof. The lens holding part holds the solid immersion lens so that light emerging from the solid immersion lens to the base part side travels through a region outside the lens holding part and toward the base part, and the base part has a light passing portionwhich transmits the light toward the objective lens. Since the lens holding part extends in the direction of the optical axis L of the objective lens, even in a case where an observation objectis observed as located on a bottom surface of recess, the lens holding part will be prevented from contacting a side wallof the recess. As a result, it becomes feasible to observe the observation object up to a region closer to the vicinity of peripheral partof the observation object. This provides a solid immersion lens holder allowing observation up to a region closer to a peripheral part of an observation object even in a case where the observation object is set in a recess of a sample.
