Collection angle is a key component of the process used to aim optical instruments and determine their direction of view. It is measured in degrees and is used to determine the opening angle of the instrument’s aperture.

Collection angle is typically used to describe the angle of the opening of a telescope or camera lens. This angle affects the field of view and the amount of light entering the lens. The larger the angle, the greater the field of view and the more light that can enter the lens. Generally, a larger collection angle can increase the sensitivity of the instrument.

Collection angle can also be used to refer to the angle of view for an entire system, such as a satellite or space mission. This could refer to the entire swath of area observed by the mission, or to the entire field of view of a telescope or camera.

Collection angle is also sometimes used to describe the power of a particular optical system. This is done by multiplying the collecting angle of the instrument by the aperture of the telescope or lens. The result is a number that represents the power of the instrument. This number can then be used to compare the performance of different optical systems.

Collection angle is an important part of the process of aiming optical instruments and setting their direction of view. By understanding the implications of this angle, we can determine the optimal viewpoint for different optical systems.
