Abstract:
An optical device for microscopic observation  4  comprises: a cold stop  13  having openings  13 d,  13 e  corresponding to a low-magnification microscope optical system  5  and being a stop member arranged in a vacuum vessel  12  to let the light from the sample S pass to the camera  3 ; a warm stop  10  having an opening  14  corresponding to a high-magnification microscope optical system  5  and being a stop member arranged outside the vacuum vessel  12  to let the light from the sample S pass toward the cold stop  13 ; and a support member  11  supporting the warm stop  10  so that the warm stop can be inserted to or removed from on the optical axis of the light from the sample S, wherein the warm stop  10  has a reflective surface  15  on the camera  3  side and wherein the opening  14  is smaller than the openings  13 d,  13 e.

Claim (Index 22):
