Optics Tools & Calculators
Free, instant, no sign-up. Every one of these restates an advertised figure as a delivered figure — watts at the workpiece rather than draw at the plug, hazard distance in metres rather than the word eye-safe, magnification the aperture can carry rather than the number on the box — and shows the arithmetic, so you can rerun it against a product we have never had on the bench.
Optical Watt Calculator
Turn an advertised wattage into the optical watts that reach the workpiece, then into the energy density that decides whether a pass cuts through.
Open toolNOHD & Eye-Safety Calculator
Enter power, divergence and wavelength for the nominal ocular hazard distance in metres — and the eyewear rating your working distance actually needs.
Open toolMagnification Ceiling & True Field
Find the magnification an aperture can deliver under the sky you observe from, what it resolves, and the true field any eyepiece leaves you.
