Edmund Optics has introduced TechSpec spherical aberrationcompensation plates optimized for use in collimated light with small fields ofview. Leveraging a precision BK7 substrate, these ...

Schäfter+Kirchhoff offer different fiber couplers for collimating the beams exiting polarization-maintaining (PM) and singlemode fibers, as well as for coupling into PM fibers from free space (type ...

Towards the end of the 19th century, Abbe and Rayleigh formulated the principles of optical diffraction that limits the resolution of optical instruments in the far-field where the distance between ...

A plano-convex cylindrical lens is used to condense light in one axis. A positive cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to ...
