Fresnel lenses are composed of a series of concentric grooves etched into one side of a sheet of plastic. Fresnel lenses are unlike typical spherical or aspherical optical lenses.
The TECHSPEC® MercuryTL™ Liquid Lens Telecentric Lenses combine the parallax error correction and high image quality of a telecentric lens with the flexibility of an integrated liquid lens.
Greg Hollows, Vice President of the Imaging Business Unit for Edmund Optics, discusses the three different types of ruggedization for imaging lenses and how they can maintain the optical performance of your imaging lens.
Aspherized Achromatic Lenses, exclusive to Edmund Optics, are doublet lenses consisting of two cemented optical elements that are matched for their color-correction ability and small RMS spot size.
Collimated light is required for many fiber optic applications. Using the proper setup, fiber optic collimating lenses or ball lenses, and some optical know-how, you can achieve optimal collimation.
Telecentric Lenses can grow quite large and heavy with small magnifications, as such magnifications require large front optics. Learn more at Edmund Optics.
Do you want to know more about the importance of optical specifications? Learn the different types of specifications and their impact on your system at Edmund Optics.
Fresnel lenses come in different sizes and can be used in a variety of applications. Read more about the theory, manufacturing, and application use at Edmund Optics.
Large field of view telecentric imaging lenses allow for reduction of measurement and inspection time. Learn more about large FOV lenses at Edmund Optics.
The growth of automation has introduced machine vision lenses to more harsh environments involving shock, vibration, contaminants, and temperature swings.
Laser optics high reflectivity mirrors meet exceptional specifications that Edmund Optics' competitors often fail to meet. Learn more at Edmund Optics.
Color-corrected optical lenses are ideal for many applications because they reduce multiple aberrations. Learn more about the advantages at Edmund Optics.
This comparison of the performance of aspheric, achromatic, and spherical PCX lenses in different situations reveals the ideal use cases for each type of lens.
