    Color Wavelengths
AI Thread Summary
Dichroic filters can be used to reflect specific wavelengths of light by employing layers of dielectrics. These filters selectively transmit or reflect certain colors, making them suitable for applications requiring wavelength-specific reflection. The discussion also touches on the potential use of paint, although the effectiveness of paint in achieving narrow wavelength reflection is questioned. The original poster seeks further clarification and advice on the topic. Overall, the conversation highlights the feasibility of creating mirrors or panels that reflect designated color wavelengths.

I was thinking today about whether or not mirroring could be altered to reflect only certain wavelengths of the spectrum? I couldn't think of specified way to do such a thing, thought maybe some more adapted minds could lend some advice. Thanks for any help on the topic.

Yes. These are called dichroic filters, which transmit or reflect certain wavelengths by using layers of dielectrics. Look it up.
 
Will do. Thanks for the direction.
 
Paint? How narrow a spectrum do you want?
 
Thread 'A quartet of epi-illumination methods'

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...
