where theta is the angular field of view. This formula lets you figure out the angle of view of the camera. Let’s take an example :What is your working distance to get an 10″ field of view with a 50mm lens on a linescan camera with array length 0.6″? This is the approximate w...
When this gets ineffective, put black paper under the mirror to give a dark background. Focus an image of the filament of a bright desk lamp on the surface of the mirror with a positive lens such as a magnifying glass. Angle the light at approximately 45 degree so that the back of the...
The target distance driven by the z-axis should be simultaneously controlled. That is to say, the z-axis should move to a specific position when y-axis moves to a certain position for guaranteeing that the practical removal amount is the same as that of the theoretical calculation. However,...
where λ is the mean-free path (average distance of free movement of molecules between two consecutive collisions), and L is the characteristic length. The calculation formula for the mean-free path (λ) is 𝜆=12−−√𝜋𝑑2𝑛,λ=12πd2n, (6) where d = 0.4 nm for the ...
