Edmund Optics® offers a wide variety of free online technical calculators for free on topics ranging from laser spot size, determining imaging system parameters, and infinite conjugate tube length.
FEATURED Tech Tool IMAGING
Determine the best machine vision lens for your application by simply providing your camera, working distance, and field of view.
Tech Tool Lasers
Mathematically model beam propagation of Gaussian beam using simple geometric parameters.
With a collimated beam as the input, calculate the outer ring diameter and the line thickness an Axicon will produce.
Determine spot size of our lasers and laser diode modules from user supplied working distances.
Scale a known laser induced damage threshold (LIDT) at a given wavelength, pulse duration, and beam diameter to a new LIDT at a different set of application specifications.
Tech Tool Imaging
Determine parameters critical for choosing the right imaging system for your application.
Relate optical and mechanical parameters of simple lenses in order to ease integration into application assemblies.
Determine limiting resolution of an optical or imaging application setup.
Determine basic parameters for finding the best lens for one's desired magnification.
Tech Tool Illumination
