Diffraction grating calculator5/6/2023 ![]() GD-Calc is available for download on Code Ocean. KJ Innovation offers support and consulting services relating to customized simulation, design, and optimization of grating structures using GD-Calc and other more advanced software tools. GD-Calc is available online at no charge. the form of a diffraction grating ) is used to reflect a selected portion. The formula for diffraction grating is used to calculate the angle. ![]() The code and documentation provide a wealth of technical and instructional information and computational capabilities for a broad range of grating types. The first calculator to use LCD technology was introduced by Sharp in 1973. The Calculations box will calculate the angle of incidence and the angle of diffraction for the desired wavelength. GD-Calc is implemented entirely in MATLAB, providing a convenient, user-modifiable interface, and making it easy to incorporate grating components in MATLAB-based system simulation models. Enter the desired values in the white boxes. Engineers, scientific programmers, researchers, and students with an interest in optics will find GD-Calc and the accompanying documentation to be a very useful resource for diffraction grating analysis. Additionally, the calculator gives the Littrow angle, which is the incidence angle optimized for highest diffraction efficiency in blazed transmission gratings. GD-Calc, the Grating Diffraction Calculator™, computes optical diffraction efficiencies of diffraction gratings and periodic structures comprising linear, isotropic, and non-magnetic optical media, based on a generalized variant of rigorous coupled-wave (RCW) diffraction theory. ![]()
