Zemax Opticstudio v20.3.2

NATIVE VOLUME HOLOGRAMS (ALL EDITIONS) AND DIFFRACTION EFFICIENCY ANALYSIS (PROFESSIONAL AND PREMIUM EDITIONS, SUBSCRIPTION ONLY) Volume holograms and their analysis are now natively supported in Sequential Mode. This release brings new native volume holograms and Diffraction Efficiency analysis tools to Sequential Mode that were previously only possible using DLLs. This allows the full simulation of volume holographic gratings in Sequential Mode by considering properties such as material shrinkage and index shift. Now it is possible to calculate diffraction efficiency using Kogelnik’s method for thick holograms and to simulate images. There are 3 new analyses available: Efficiency vs. Angle, Efficiency vs. Wavelength, and Diffraction Efficiency. To find these new analysis tools, select Analyze > Diffraction Efficiency

1.2 NEW ROLL TOLERANCE OPERANDS (ALL EDITIONS) Six new roll operands make it easier to tolerance bonded elements. OpticStudio 21.1 features six new roll operands: TRLX, TRLY, TRLR, TARX, TARY, and TARR. These are designed for tolerancing bonded components, where elements can be cemented out of alignment creating a roll between the surfaces in contact. These new roll operands model this misalignment as a rotation about a surface’s center-of-curvature. The minimum or maximum roll can be quantified as either total indicator runout (TIR) or as the angle between the optical elements. 1.3 NEW RADIAL DECENTER TOLERANCE OPERANDS (ALL EDITIONS) Two new radial decenter operands designed for systems with circular optics. Two new decenter operands: TEDR and TSDR for tolerancing elements and surfaces respectively, expand on the existing decenter operands in OpticStudio by adding the ability to decenter along a random radial axis. This is recommended when modelling circular optics in circular mounts such as traditional camera lenses or microscope objectives where the existing Cartesian decenter operands could cause a bias towards the 45° diagonals between the X and Y axes. 2 FEATURE EXPERIMENTS 2.1 NEW OPTIMIZATION METHODS (ALL EDITIONS) New DLSX and PSD optimization methods have been added. DLSX (streamlined DLS) and PSD (pseudo-second derivative) optimization methods have been added for use with Local, Global and Hammer optimizations. To activate this Feature Experiment, select Help > Feature Experiments > New Local Optimization Methods. 2.2 ENHANCED WIDE ANGLE RAY AIMING (ALL EDITIONS) Improves speed and stability of ray aiming in wide angle systems. This Feature Experiment improves ray aiming if either Paraxial or Real Ray Aiming is enabled in System Explorer. Most of the improvement in speed and stability also requires Robust Ray Aiming to be enabled. This will have the greatest effect on wide angle lenses, off-axis systems and lenses starting with an aspherical element. To activate this Feature Experiment, select Help > Feature Experiments > Enhanced Wide Angle Ray Aiming
