1. Basics
1.1 BASICS Lens Construction In this video tutorial, a simple singlet lens is created using the Lens Wizard and the construction of the lens is explained in the Optical Design Editor. Video: 2:10 min
1.2 BASICS Raytracing In this video tutorial, a light sequence is traced through a singlet lens by adding a source and an imaging surface. In addition the autosequence is explained. Video: 3:25 min
1.3 BASICS Enhance Computing and GUI Performance In this video tutorial it is explained how to enhance the computational performance to increase the computing speed and to accelerate the graphical user interface. Video: 4:15 min
2. Construction
2.1 CONSTRUCTION Freeform & Stack Definiton In this video tutorial we learn how to create freeforms by adding different shapes to a lens (e.g. aspheres, Gauss peak, cosine structure). With the stack definition, any number of shapes can be combined with each other, which gives maximum flexibility with regard to the shape definition of a lens surface. Video: 4:33 min
2.2 CONSTRUCTION Assembly In this video tutorial multiple lenses are assigned to a common assembly. An assembly has its own coordinate system which allows to position, move or rotate all elements in the assembly, such as lenses or surfaces, together. In addition a tolerance analysis can be performed for a single assembly, which enables a very realistic tolerance analysis of the optical system. Video: 2:12 min
2.3 CONSTRUCTION Global & Local Coordinate System In this video the difference between a local and a global coordinate system is explained. Video: 2:11 min
2.4 CONSTRUCTION Absolute & Relative Positions This video tutorial explains the absolute or relative positioning of elements within a coordinate system. Relative positions relate to the position of the last surface of the previous element, whereby an absolute positioning is referring to the absolute value in the coordinate system. Video: 2:23 min
2.5 CONSTRUCTION Lens Catalog This video tutorial explains how to insert lenses out of the lens catalog and how to filter the catalog by different filters. Video: 1:47 min
2.6 CONSTRUCTION Multiconfig Lookup Table & Parameter This video tutorial explains how to insert parameters instead of numerical values by using the Multiconfig Lookup Table. Video: 3:25 min
2.7 CONSTRUCTION Slider Interface & Parameter In this video the Slider Interface is explained. With the Slider Interface parameters can be defined by a minium and a maximum value. The Slider enables a sliding between these values. Video: 3:29 min
2.8 CONSTRUCTION 3D-View Editor This video explains how to edit lens- and surface parameters directly inside the 3D-View without having to switch to the Optical Design Editor. Video: 2:15 min
2.9 CONSTRUCTION Convert Surface Form Wizard In this tutorial I will show you how to convert a form description of an Asphere into the form description of a Qbfs Q-Type-Asphere without changing the shape of the form and without changing the optical system. Video: 3:00 min
2.10 CONSTRUCTION Adding Measurement/Simulation Data to Surface In this tutorial I will show you how to add data from measurements or from simulations as for example from mechanical FEM simulations to a surface. Video: 2:04 min
3. Raytracing
3.1 RAYTRACING Auto Sequence & Sequence Fields The Auto Sequence is explained in this video tutorial. It shows how the Auto Sequence is created and how rays can be traced through a system that consists of several lenses. It also explains how to adjust the source properties and how to define fields. Video: 3:09 min
3.2 RAYTRACING User Sequence The User Sequence is explained in this video tutorial. With a User Sequence the sequential paths through a system can be defined completely invdividual. This makes it very easy to simulate systems with multiple sequential paths, such as interferometers, or to perform sequential reflex analyzes. Video: 3:14 min
3.3 RAYTRACING Ghost Reflex This video tutorial explains how ghost reflexes can be generated and how the reflexes can be analyzed individually. Furthermore, it is shown how the ghost reflexes can be sorted according to the maximum illuminance or the maximum total flux in order to easily identify the most problematic reflexes. Video: 4:31 min
3.4 RAYTRACING Ghost Reflex Analysis In this video the intensity of the ghost reflexes and the distribution of the ghosts on the imaging surface will be analysed. Video: 3:24 min
4. Polarization
4.1 POLARIZATION Polarized Light Source This video describes how to set up a polarized Light Source (e.g. Circular Polarization or Jones Complex) and how to define the Polarization Settings in the Source. Video: 3:09 min
4.2 POLARIZATION Polarization Elements In this video it is shown how to add Polarization ELements as a Quarter Wave Plate or a Jones Matrix to a Lens Surface. Video: 3:14 min
5. Mechanics
5.1 MECHANICS Import & Intersection Analysis In this video mechanical elements are imported to the optical system. Furthermore it will be analysed if there is an intersection between the optical rays and the mechanical parts. Video: 2:53 min
6. Analysis
6.1 ANALYSIS Basic Plot Settings This video describes how the Analysis Plots can be set up and how settings can be changed. Video: 1:46 min
7. Optimization
7.1 OPTIMIZATION Spot Radius Optimization In this video the spot radius of an optimization of an achromatic doublet is shown. The Merit Function is defined with different Optimization Goals/Targets and in addition it is shown how to set up Lagrange constraints. Video: 4:35 min
7.2 OPTIMIZATION Material Substitution In this video it is described, how to substitute Materials by using the Extended Optimization. Video: 2:29 min
7.3 OPTIMIZATION Math Expression In this video tutorial it is described how to use a math expression for the optimization. It is also shown how to perform a computation in the math expression with different variables or tracing targets. Video: 2:08 min
8. Tolerancing
8.1 TOLERANCING Define Tolerances This video describes how to setup a Tolerance Analysis and how to define Global & Specific Tolerances for single elements. Video: 3:46 min
8.2 TOLERANCING Sensitivity Analysis & Monte Carlo Simulation In this video a Sensitivity Analysis and a Monte Carlo Simulation is performed. In addition it is described how the tolerances have an impact on the Merit Function. Video: 2:37 min
9. Scripting
9.1 SCRIPTING Python Interface This video explains the basics of the Python Scripting Interface and shows how to use the Python Wizard to create a PSF Plot and a Spot Diagram. Video: 2:57 min
