Get to know the Optical Aberrations present in your Image


By Stuart W. Singer and Jim Sullivan

This article explains why simply looking at a Modulation Transfer Function (MTF) plot is not enough to fully evaluate a lens or diagnose imaging issues. While MTF data accounts for all optical aberrations, it doesn’t reveal which specific aberrations are affecting the image. To achieve optimal optical performance, understanding individual aberrations is crucial. The article also discusses various types of aberrations like spherical and chromatic, how they vary with lens settings, and the importance of using ray aberration plots for more accurate analysis.

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.
