Saving the lens for last?

By Stuart W. Singer and Jim Sullivan

The perfect lens may not always be immediately available, which can lead to difficult decisions such as delaying the project for a custom solution or compromising on specifications. A new approach is required: concurrent engineering. By involving experts from the beginning, we can avoid costly trade-offs and fully realise our innovative designs. Let us prioritise the lens and collaborative design to ensure smoother projects with greater potential.

Do you know what you are really buying?

By Stuart W. Singer and Jim Sullivan

Technical data sheets for optical lenses are not standardized, allowing vendors to present data in any way they choose, potentially leading to misleading claims and preventing fair comparisons. Generic terms like MTF often lack clarity about what they measure and how they're calculated, leaving buyers to decipher. Even when specifications are governed by standards such as ISO or DIN, they're often poorly understood and leave significant leeway.

Specifying lenses for megapixel cameras

By Stuart W. Singer and Gregory Hollows

Continuing advances in high-resolution sensors with higher pixel densities and smaller pixels are challenging optics manufacturers to produce lenses with increased performance. To understand how lenses can affect the performance of imaging systems, it is necessary to grasp the physics behind diffraction, lens aperture, focal length, and the wavelength of light.
