Optilayer optical thin film design software is considered to be the fastest, most powerful and most user-friendly thin film design software. The software consists of three modules: OptiLayer thin film design main module, OptiChar optical parameter calculation module and optiRe engineering inversion module.

Thin film design main module OptiLayerThe unique needle optimization algorithm provides excellent convergence speed and accuracy. Optilayer is the only software that uses analytical algorithms to calculate the gradient of the optimization function and the Hesse matrix for all optimization processes.Capable of analyzing a single target or comprehensive analysis of multiple targets, such as spectral feature targets, color targets, and electric field strength targetsAble to design and analyze various thin films: anti-reflection films, high-reflection films, various filters, beam splitters, polarizers, chirped mirrors, color films (CIE xyz, CIE L*b*, CIE H0LC, CIE L*u*v*, Hunter Lab), etc.The only thin film software that can accurately design group delay and group delay dispersion characteristicsOptimization of single lens film and multi-lens optical system filmFor beginners, the carefully developed interface and multiple automatic modes can solve the most complex design problems. Most designs can be automatically optimized starting from a single layer.For experienced designers, special design modes can meet the most complex requirements and enable all your experience to be effectively applied to a variety of design problemsBroadband and multi-wavelength monitoring simulation capabilitiesThe filter automatic design interface only needs to input parameters such as wavelength and bandwidth to automatically optimizeCapable of simulating and analyzing film interface roughness modelsFor dispersive and absorbing films, it is possible to analyze a large spectral range and a wide incident angleError analysis of thin film material refractive index and coating thicknessThe software is updated at least once a year to enable the software to integrate the latest coating equipment and coating processes

Parameter calculation module OptiChar
OptiChar is the only software module that can accurately calculate the optical parameters of a single-layer film. Whether it is an absorbing film or a non-absorbing film, the calculation model provided by the software can be used to accurately calculate the refractive index and extinction coefficient. The calculation models include Cauchy model, Selleier model, Hartmann model, n and K model (applicable to complex problems that cannot be solved by the previous models)
Main features of the calculation module:
- Calculate the refractive index n and extinction coefficient K of the film material, including metal film, dielectric film, ITO film, etc.
- Analyze n and K of the substrate material
- Calculate the thickness of the single-layer film based on the transmittance and reflectivity of the film
Can directly import spectral data from Alilent, Perkin Elmer, Woollam, Hitachi and other spectral instruments
- Can select data columns to import from Excel tables and TXT texts

Engineering Inversion Module OptiRe
OptiRe is specially developed for engineering inversion using spectrophotometer/ellipsometer measurement data. It provides feedback information for the thin film deposition process, can find the source of film thickness error during thin film deposition, and improve the process level. OptiRe uses an independent algorithm and multiple analysis options to extract as much information as possible from the experimental data, including random error analysis model, systematic error analysis model, refractive index correction model, etc.
OptiRe inversion results are given in the form of charts, which can be film thickness error, corrected refractive index and extinction coefficient, etc.

Dynamic Link Library OptiReOpt
OptiReOpt dynamic link library (optional installation) is not an interface, but a series of DLL dynamic link libraries that can be used. It can be embedded in any environment that supports calling, such as
- Microsoft Visual Studio version 6.0 (C++, Visual Basic)
- Microsoft Visual Studio 2005-2017 (C++, C#, Visual Basic)
- Embarcadero C++ Builder (any version)
- Embarcadero Delphi (version 5.0 and higher)
- LabVIEW version 5.xx and higher
- Java (at Windows platform)
OptiReOpt can be used to monitor the deposition process of thin films. Combined with a wide spectrum film thickness monitor, it can correct design parameters during the coating process and achieve design while coating.
