AI Thread Summary
In an infinity-corrected optical microscope, the object plane does not overlap with the focal plane unless the object is intentionally positioned at the focal plane. The best imaging occurs when the specimen is located at the front focal plane of the infinity-corrected objective. Proper alignment of the microscope is essential for optimal imaging. The discussion confirms that correct focusing is crucial for achieving the best results. Understanding these principles is key to effective use of infinity-corrected optical systems.

Hi

I am not sure whether the object plane overclaps focal plane in a infinity-corrected optical microscope.
Thanks!
 
Science news on Phys.org
They do not, unless the object is deliberately located at a focal plane.
 
I mean when the miscroscope is well focused. Is it the object that in the focal plane can be best imaged?
 
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！
 

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
