Although a common misconception, individual optical lenses do not always form an image when the object plane is placed a focal length away from the lens.
Join Stefaan Vandendriessche, Sales and Applications Engineer, as he demonstrates a Differential Interference Contrast (DIC) microscope built from stock components found in the Edmund Optics catalog.
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.
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.
Telecentric illumination is quickly becoming the illumination of choice for precision metrology due to its ability to produce "hard" edges that can be easily analyzed.
Polarization Directed Flat Lenses, which are formed with polymerized liquid crystal thin-film, create a focal length that is dependent on polarization state.
Imaging lens assemblies are vital components for a wide range of cutting edge applications including machine vision, biomedical instruments, factory automation, and robotics.
