1 Tools, Features, and Capabilities

1.1 QUICK YIELD (PROFESSIONAL AND PREMIUM EDITIONS, SUBSCRIPTION ONLY)

Get tolerancing predictions throughout the design process in a matter of seconds

OpticStudio 20.2 has a new advanced capability which simulates full Monte Carlo tolerancing runs in a fraction of the time. This analysis should be used throughout the design process to guide design decisions as they pertain to creating more manufacturable systems. Quick Yield can be found in The Tolerance Tab > Quick Yield

1.2 TOLERANCE DATA VIEWER (ALL EDITIONS)

A new streamlined viewer to easily access all sensitivity and Monte Carlo tolerance data

The Tolerance Data Viewer is a new viewer which displays all Monte Carlo and sensitivity data in a spreadsheet format. In addition to any data listed in the Tolerance Data Editor, this viewer also includes any reported data in a tolerance script. Additionally, as part of this viewer addition, tolerance runs can now be saved in .ZTD files, and opened in the other tolerance analyses as well. This viewer will open by default on the end of a tolerance run and can also be found in The Tolerance Tab > Tolerance Data Viewer.

1.7 DESIGN TEMPLATES DATABASE (ALL EDITIONS, SUBSCRIPTION ONLY)

Easily and quickly find a starting point for your system

Design Templates gives you an easy and convenient way to search for a new starting system that matches the base specifications you are looking for. You can search based on any information in the prescription data. Design Templates can be found in The Libraries Tab > Design Templates.

1.8 NEW DLL: SRG_GRIDWIREPOLARIZER _RCWA.DLL (PREMIUM EDITION, SUBSCRIPTION ONLY)

Model Grid Wire Polarizer gratings with diffraction efficiency using this DLL

Using this new diffractive DLL, Grid Wire Polarizer gratings can now be modelled with accurate calculation of diffraction efficiency. This DLL can be used in non-sequential mode in the Diffraction Object Properties of the User Defined Object, Diffraction Grating. More information about this functionality can be found in the Knowledgebase article “Simulating diffraction efficiency of surface-relief grating using the RCWA method”.

1.10 NEW SOURCE DLL: SKEWRAYSCIRCULAR.DLL (ALL EDITIONS)

Model gaussian beam propagation in non-sequential mode using skew rays

This Source DLL sends skew rays to model Gaussian Beam Propagation in non-sequential mode. Skew rays are an efficient and accurate representation of Gaussian beams and can be used to quickly optimize for best focus or to minimize aberrations. It is the non-sequential equivalent of Paul Colbourne's user defined surfaces: Using skew rays to model Gaussian beams

Calculate the In-Air EFL of any lens

CARD calculates the cardinal points of the system.

 

2 Programming

2.1 ZOS-API PYTHON: .NET SUPPORT (PROFESSIONAL AND PREMIUM EDITIONS)

The ZOS-API through Python now supports the .NET framework

OpticStudio now supports and recommends using Python with the .NET framework in the ZOS-API. Since the ZOS-API is written using the .NET Framework, using languages that can directly communicate with .NET will give the most flexibility and the best performance. More information about this update can be found here: ZOS-API using Python.NET
