Selecting an optimum lens for your camera or sensor
Service News Thursday, February 13, 2025: Resolve Optics Ltd.
Resolve Optics has written a white paper which discusses the key considerations when selecting a lens to get optimum performance from your camera or sensor.
The ability of a lens to resolve detail is not only determined by its quality but also is ultimately limited by diffraction. It is commonly thought that the resolution of a lens should match or exceed the Nyquist resolution of the sensor that it has been selected to work with, to achieve optimum performance. This is a common misconception.
The white paper discusses and explains design considerations such as ‘What is the Nyquist resolution of your sensor and why is it important’, ‘How lens resolution can be affected by Moiré and aliasing affects’ and ‘Why a digital sensor can only sample an analogue signal that is half its Nyquist sample rate’.
