UV Tools – Calculators and Analysis Tools for UV and Lighting Applications
The Opsytec UV Tools are freely accessible calculators and analysis tools for designing and assessing UV and lighting applications. They cover irradiance, UV dose, exposure time, photon energy, photon flux, PPFD, transmittance and optical density, provide a spectra database explorer and offer 3D simulations for UV LED arrays and irradiation chambers. The results serve as a first estimate and do not replace a measurement with calibrated instruments.
3D Simulation of a UV Irradiation Chamber
The UV irradiation chamber simulator allows users to virtually calculate irradiance and UV dose for various BS and BSL irradiation chambers. Power, wavelength, measurement plane, and target object can be customized, and the results can be displayed as a heat map, 3D view, or simulation report.
UV-LED 3D Irradiance Calculator
The UV-LED 3D Irradiance Calculator calculates the irradiance and uniformity of configurable UV-LED arrays on flat, inclined, or imported 3D target objects. The LED arrangement, wavelength, power, working distance, and radiation pattern can be customized. The results are visualized in three dimensions and can be exported as a CSV file, cross-sectional profile, PNG image, or PDF simulation report.
UV LED Spot Sources: Simulate Irradiance
The UV LED spot source simulation calculates beam profile and irradiance of the UV LED spot sources solo P, Spot P and Spot P short for the Standard, High Power and Parallel Beam optics at 365–450 nm – with heat map, 3D view, cross-section profiles, multi-spot arrangements (up to 16 spots), STEP/STL import and CSV/PDF export.
Integrating sphere design as luminance and radiance standard
The integrating sphere design app calculates radiance, luminance, and spectral radiance for individually configured Ulbricht spheres. The sphere diameter, coating, ports, lamp type, and lamp power can be customized. A 3D view and an automatically generated PDF report assist in the preliminary design of optical measurement and calibration systems.
Interactively analyze spectral data from various UV light sources
The Spectral Database Explorer provides interactive access to measured spectral data from various UV light sources. The database includes typical emission spectra of UV LEDs and UV lamps and allows for a direct comparison of different radiation sources across their respective wavelength ranges. The underlying spectra were measured in the Opsytec laboratory and serve as a reliable basis for evaluating the spectral properties of UV sources.
Find and look up
Which sensor fits, which standard applies, who has already worked with it? The tools for searching rather than calculating.
Converting optical quantities
Irradiance, dose, exposure time, transmission, photon energy and belt speed: the calculators for converting optical quantities.
Notes on the Opsytec UV-Tools Web Applications
The UV tools are intended to provide a rough guide and are not a substitute for measurements taken with calibrated instruments. The calculations are based on simplified model assumptions. Actual values may differ significantly.
Disclaimer of Liability and Warranty
No warranty is provided regarding the accuracy, completeness, or suitability for a specific application. Liability for accuracy, completeness, and timeliness, as well as for damages resulting from the use of the tools or decisions based on them, is excluded to the extent permitted by law. The tools do not constitute any representation of quality or warranty and are not intended for process approvals, validations, risk assessments in accordance with OStrV / Directive 2006/25/EC, or medical applications. Binding values must be determined through metrological measurement.
