Forming an Image with a Convex Lens

AI Thread Summary
A convex lens can form an image at the focal point if the object is placed at infinity. For objects that are far but not at infinity, the image will be nearly at the focal point. The relationship between the object distance, image distance, and focal length can be calculated using the lens equation: 1/f = 1/o + 1/i. This equation helps determine the precise distances involved in image formation. Understanding these principles is essential for practical applications of convex lenses.

Using a convex lens, can an image be formed at the focal point and if so where would the object have to be from the convex lens?

An object at infinity on one side of the lens will focus at the focal point on the other side.

In practice, if the object is far but not at infinity, the image will still be very close to the focal point. You can calculate this using the lens equation: 1/f = 1/o + 1/i
where
f = focal length
o = object distance
i = image distance
 
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...
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...
