Abstract:
An observation device  100  includes an objective  2 a , camera  3 , an observation scope changing device, and a control device. The objective  2 a  having from 4× to 20× and including a positive lens group forms an image with light from sample S. The lens group includes a single lens L 1  having a concave surface on an object side and a variable aperture diaphragm  4 . The camera  3  converts the image into an image signal. The observation scope changing device performs electronic scaling on the image signal and performs an observation scope changing process. The control device controls the diaphragm  4  in accordance with the observation scope changing process. The observation device  100  satisfies a conditional expression is satisfied, 3≤| fa/fGS |≤10 where fa is a focal length of single lens L 1  and fGS is a focal length of a lens group from an object plane to the diaphragm  4.

Claim (Index 2):
The observation device according to  claim 1 , wherein\n the objective includes a first lens group and a second lens group, the first lens group being arranged on an object side of a portion having a largest lens-surface interval, having the single lens and the variable aperture diaphragm and having a positive refractive power, and the second lens group being arranged on an image side of the portion having the largest lens-surface interval and having a positive refractive power.
