Technology nodes are shrinking but the wave length and numerical aperture (NA) of the UV light used in photo lithography process is still a major concern for the manufacturers. The result is that the ...

Microelectromechanical system (MEMS) optical modulators are crucial in next-generation technologies such as free-space ...

An aperture mask is a simple device for easier observing that increases the effective focal ratio of a telescope.

As shown in this paper, a contribution of distant sources to the light pollution might be essential under specific conditions of low turbidity and/or Garstang-like radiative patterns. To evaluate the ...

Here's what you need to know. Aperture determines how much light can pass through a lens at a given shutter speed. This photography cheat sheet explains when to go wide and when to go narrow. The ...
