Three Lasers Converging at a Focal Point : A Demonstration
... 1. Clear a space on a table. Set up three lasers next to each other so they will produce parallel beams of light. The lasers need to be close together so they all pass through the lens. There are two ways to accomplish this. One is to not use the supports and use a rubber band to hold the lasers tog ...

Spider Silk: The Mother Nature`s Biological Superlens
... To summarise, this paper verified that the minor ampullate spider silk, spun from the Nephila edulis spider, has the properties to perform as an optical superlens by utilising photonic nanojets to carry the surface information at a highspatial-frequency, which can resolve 100-nm objects and patterns ...

4.8 Acceptance Angle and Numerical Aperture
... The grid slide or screen and ruler can be used to measure diameters. The edges of the cone of light may appear fuzzy so there will be an error introduced into your measurements. Measurement of the edges is an approximation to the notion of Full Width Half Maximum (FWHM). This is how light boundaries ...

An additional 76.5mm of space between the tube lens and objective is optimal, but it is common to only use about 56.5mm of space between #55-743 and #58-329 since each adapter adds about 10mm of space. With this 56.5mm of space, use extension ...
