Contrast Loss Map in OpticStudio 17.5

Contrast Loss Map is a new feature in OpticStudio 17.5 that provides an easy way to understand how contrast varies or is lost in an optical system. It visualizes contrast loss for a specific frequency of the Modulation Transfer Function (MTF) as a distribution map across the exit pupil. Contrast Loss Map gives insight into how the MTF is degrading across the pupil. You can then use the data to determine what changes to make to your system to improve MTF. Contrast Loss Map plots the same contrast loss values that are calculated during Contrast Optimization, a new capability introduced in OpticStudio 17 that uses the Moore-Elliott method to optimize for MTF at least 30 times faster than traditional methods.

Adjusting Relative Luminosity to Simulate the Visible Spectrum

Relative luminosity is very important in optical design. By defining appropriate weighting per the characteristics of the optical system, we can better model what we would expect to see. This article demonstrates a method of using wavelength weighting to model the relative luminosity of the visible spectrum as perceived by the human eye.

Display Pupils on a Layout Plot

You can easily show the Entrance and Exit Pupils in both the LDE and Layout Plots by using dummy surfaces and pickups to show the location of the pupils without affecting the other surfaces in your sequential system.  This article walks through how to use ZPL Macro and Chief Ray Height thickness solves in the Lens Data Editor (LDE) as well as hiding dummy surfaces in a layout plot.

Modeling Optics with Realistic Edge Apertures

OpticStudio 16 offers a comprehensive way to model realistic lens apertures with opto-mechanical semi-diameters. Three separate apertures (semi-diameter, chip zone, and mechanical semi-diameter) offer the ability to define a lens component the same way it is made.
