Abstract: A microscope objective includes: a first lens group that has a positive refractive power and includes a first cemented lens; and a second lens group, the first lens group and the second lens group having concave surfaces adjacent to and facing each other. The second lens group includes: at least one lens component that has a negative refractive power overall; a second cemented lens; and a single lens having a positive refractive power.

Abstract: A device and method for judging the presence or absence of an abnormal clearance between paring elements of a passive joint of a robot. The device has sections configured to: calculate a score for each motion path, wherein the score is increased when the paring elements of an objective pair collide with each other and is decreased when the paring elements of the other pair collide with each other; generate a robot motion for moving the robot along the motion path having the score not lower than a predetermined threshold; measure a drive torque or a current value of a motor when the robot is moved according to the generated robot motion; calculate an index value based on a magnitude of variation of the measured drive torque or current value; and judge as to whether the abnormal clearance exists in the objective pair, based on the index value.
