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
Relate optical and mechanical parameters of simple lenses in order to ease integration into application assemblies. Select index from list of EO's own optical substrates to help calculate focal lengths and principal points of any standard lens.
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.
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.
Determine the best standard lenses option for your application based on your field of view, working distance, and camera sensor size.
Tech Tool Misc.
Relate user supplied magnifying power to focal length and diopters of a lens.
Tech Tool Illumination
Mathematically determine how to configure a source and two lenses into a Koehler Illumination setup.
Determine the illuminated spot size resulting from a collimated light source passing through a singlet.
Determine the effective focal length, the back focal length, and the effective numerical aperture of a ball lens.
Identify a compatible pair of ball lenses for coupling light from one optical fiber into another.
Tech Tool Microscopy
Determine the maximum tube length in an infinite conjugate microscope system for covering a specific image sensor size.
