Infinity-corrected optical system

[Bin Fang]

Hi

I am not sure whether the object plane overclaps focal plane in a infinity-corrected optical microscope.
Thanks!

They do not, unless the object is deliberately located at a focal plane.

 

[Bin Fang]

I mean when the miscroscope is well focused. Is it the object that in the focal plane can be best imaged?

 

[Andy Resnick]

If I understand you correctly, yes. When the microscope is properly aligned, the specimen plane is located at the front focal plane of an infinity-corrected objective.

thank you！
