Resolve Optics has written a white paper that discusses the key considerations when selecting a lens to obtain optimum performance from your camera or sensor.
The ability of a lens to resolve detail is determined by its quality as well as 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.’
Over the last 25+ years, Resolve Optics has developed a customer centric approach to specialist lens design, development, and supply. Each year the company delivers thousands of custom lens assemblies – from complex high-speed imaging optics and material sorting inspection lenses, to radiation resistant lenses for critical nuclear and space applications. The company prides itself on quickly translating each customer need into an optimized optical design, running projects successfully, and manufacturing production quantities of lenses or optical products on time, to the specified quality and target price.
