AI Thread Summary
A user seeks simulation software to visualize the collimation process of a fibre-coupled LED light source using an achromatic doublet lens. They understand that positioning the lens at its focal length will collimate the light. Suggestions include using online tools for visualization, particularly for ray optics, which are suitable unless working with mid-infrared LEDs. The discussion emphasizes the importance of clarity on the intended outcomes of the simulation. Overall, the conversation revolves around finding effective tools for visualizing optical processes.

Summary:: I have a fibre coupled LED light and an achromatic doublet lens, I know by placing the collimating lens at a distance equal to the focal length of the lens, the light will get collimated. But is the a simulation software available where I can input the parameters I can so as to visualize the process.

Can you be more specific? What are you hoping to get out of the simulation? If it's just a visualization aid, then there are online tools that can help you. Unless your LED is in the mid infrared, ray optics should be fine.
 
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...
