Designing Optical Filters

Designing Reflective Coatings with OghmaNano

OghmaNano’s advanced optical solvers provide a complete toolkit for designing, optimising, and analysing optical filters and coatings. Whether you are working on anti-reflective layers, distributed Bragg reflectors, or narrowband filters, the software allows you to visualise how photons interact with each layer of your device — revealing precisely where light is absorbed, reflected, or transmitted.

By combining accurate optical modelling with a comprehensive materials database, OghmaNano enables you to design filters that match your exact experimental conditions and performance targets.

Key Features:

Transfer matrix models for calculating wavelength-dependent reflectance, transmittance, and absorption profiles through multilayer stacks.
Extensive materials database containing wavelength-dependent n and k parameters for over 2,200 materials — from common dielectrics to exotic semiconductors.
Source spectra library including LEDs, Xenon lamps, lasers, and solar illumination standards.
Custom data import for both material optical constants and light source spectra, ensuring your simulations match your experimental setup exactly.
Advanced ray-tracing models to investigate light scattering, angular dependence, and light extraction from textured or patterned surfaces.
Optimisation tools to fine-tune layer thicknesses for maximum transmission, reflection, or rejection in your target wavelength range.

Whether you are developing optical coatings for solar cells, LEDs, photodetectors, or imaging systems, OghmaNano helps you create designs that maximise efficiency and meet real-world performance requirements.
