Optics
Interferometry Fringe Calculator
Calculate the fringe spacing produced when two coherent beams intersect at a given angle and wavelength. Use it when setting up laser interferometers, holographic recording setups, or optical metrology systems.

Optics
Laser Beam Parameters Calculator
Compute key Gaussian laser beam properties — Rayleigh range, half-angle divergence, or beam radius at any distance from the waist. Essential for laser system design, focusing optics, and beam alignment tasks.
