Solving Refraction Optics Puzzle for Color Project

AI Thread Summary
The project involves creating a window that allows viewers to see a specific color, regardless of the angle from which they look, with a focus on a single plane. The user seeks advice on suitable lenses or prisms to achieve this effect, as previous attempts with custom acrylic lenses have failed. The optics do not need to be of high quality since the goal is simply to view colors. The design constraints require that the optical elements be positioned at the top, ruling out alternatives like light guides or mirrors. Suggestions for using a concave divergent lens were raised, but further expert input is needed.

I'm building a project that requires to look through a window and see a specific color, however there are different colors either side, and depending on what angle you look through the little window with depends on which color you see. I would like it so that looking from most angles would, in effect be the same as looking on axis to it. It only has to work in one plane not two so only has to be contoured in one direction.

The optics don't have to be great as it's only viewing colors, but just wondering what types of lens/prisims I should look at to accomplish this. If anyone can shed some light I'd be really appreciative, I've been spending huge amounts of time shaping my own lenses out of acrylic and then finding they don't work. I don't have a good grasp on light and imaging so thought I'd put it out there to the experts.

The design of it means that it has to be done with optics at the top and can't be done with lightguides from the bottom, mirrors etc.

Many thanks

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...
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...
