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 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...

Thread 'The focal length of the eye and image inversion'

After my surgery this year, gas remained in my eye for a while. The light air bubbles appeared to sink to the bottom, and I realized that the brain was processing the information to invert the up/down/left/right image transferred to the retina. I have a question about optics and ophthalmology. Does the inversion of the image transferred to the retina depend on the position of the intraocular focal point of the lens of the eye? For example, in people with farsightedness, the focal point is...
