Tools for laser engineers
Reference calculators from the Midel Photonics laser optics team, for designing and specifying laser beam-delivery systems. Built on the same physics we use in our own optical design.
Calculator
Laser Spot Size Calculator
Spot diameter, beam waist, Rayleigh range and depth of focus, for free-space and fiber-coupled systems. Enter M² or BPP, or solve backwards for the optic.
Open tool Designer3D Gaussian Explorer
See the extended-depth-of-focus trade-off — usable depth against spot growth — versus an unshaped Gaussian, for your system.
Open tool Calculator3D Top-Hat Calculator
The round flat-top spot diameter and effective depth of focus for your beam shaper, with standard-product availability.
