AI Thread Summary
For optimal reflectivity of about 95% for both infrared and visible light, polished aluminum is recommended for infrared applications, while fused silica is effective for the visible spectrum. The discussion highlights the need for a cost-effective collimation material that can perform well in both ranges. Suggestions include exploring hybrid materials or coatings that can enhance reflectivity across both spectra. The importance of balancing cost with performance is emphasized, as well as the need for further research into suitable alternatives. Finding a material that meets these criteria is crucial for effective optical applications.

I need a good reflecting collimation material that is faily cheap and has a reflectivity of about 95% for both infrared and visible light. I know polished aluminum meets the criteria for the infrared, and the fused silica also works well for the visible spectrum, but I need somthing that can collimate both.

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...
