Engineering Calculators for Lasers, Optics, Vacuum & Quality
These are the 31 calculators I use for laser process development, instrument design, and production engineering. Each one recalculates as you type, keeps track of units, gives you a link that preserves your inputs, and explains the physics, assumptions, and limits underneath it.
New: the vision system configurator sizes a camera and lens for your inspection job, and the glazing performance calculator gives U-factor, SHGC, and visible transmittance for windows with low-e coatings and gas or vacuum gaps.
Formula reference
The equations behind the calculators in one place, organized like a laser-optics handbook, with symbols and units defined.
Knowledge centerExplainers & application notes
Longer articles on Gaussian beams, ablation process windows, vacuum, SPC, machine vision, and spectroscopic energy units.
Use with engineering judgment. These tools implement standard models and stated approximations for education and first-pass design. Check critical values against measurements and manufacturer data, and follow ANSI Z136 / IEC 60825 laser-safety practice. No warranty is expressed or implied.
