WebThe “Numerical Aperture” (NA) is the most important number associated with the light gathering ability of an objective or condenser. It is directly related to the angle of the cone which is formed between a point on the specimen and the front lens of the objective or condenser, determined by the equation NA = n sin ∝. WebAlternatively, if the sensor has already been chosen, the focal length can be determined directly from the FOV and WD by substituting Equation 1 in Equation 2, as shown in Equation 3. (3)f = (H× WD) FOV f = ( H × WD) FOV. As previously stated, some amount of flexibility to the system’s WD should be factored in, as the above examples are ...
