Engineering Tools
Explore the model, test the parameters, and connect the result to your application.
Open a workbench to explore optical behavior and analyze your inputs. Each tool states its assumptions and limits; meaningful engineering decisions also depend on the measurement conditions and validation of the physical system.
Optics Simulator
Explore image formation, lens systems, extension tubes, and aperture constraints with interactive ray diagrams.
Ideal paraxial optics with explicit model assumptions.
Open tool →Color Science
Analyze spectra, calculate color coordinates and color differences, and compare the effects of source, material, and observer.
Spectral calculations with declared units and reference conditions.
Open tool →ThinFilm
Model multilayer optical coatings, inspect spectral and angular response, and refine layer thicknesses against design targets.
Planar, isotropic thin-film stacks within the stated material and coherence model.
Open tool →Photographic Metrology
Connect camera meter readings with luminance, illuminance, exposure, and calibration through practical calculations and visual explanations.
Meter-based estimates that preserve calibration and diffuse-reflector assumptions.
