Edmund Optics® TECHSPEC® Aspherized Achromats bridge the gap between color-corrected achromats and spherical aberration corrected aspheres. Typical applications include: fiber optic focusing or collimation, condensing systems, image relay, inspection, scanning, beam expanders, and high numerical aperture imaging.

Achromatic lenses typically consist of cemented assembly of a low index and ... (read more)

Achromatic Focusing Objectives are aberration corrected at two wavelengths simultaneously. A doublet consisting of two lenses of different materials can be designed such that the effective focal length and performance will be the same at two separate wavelengths. (read more)

What do movies, medicine, the military and mass communications have in common? They all depend on "Optics by ELCAN" and the world-renowned optical expertise at ELCAN Optical Technologies in Midland. Customers that are leaders in their industry often turn to ELCAN to solve challenges that other suppliers have refused to attempt. This was the case with Panavision. (read more)

The FizCam 3000 is an entirely new Fizeau design, providing highly accurate measurement of optical grade surfaces even in the presence of vibration and air turbulence. Its completely on-axis design eliminates the inherent aberrations, software corrections and painstaking calibrations and alignments typical of tilted beam Fizeau systems. (read more)

LEXT- a new Confocal Laser Scanning Microscope designed for sub-micron imaging, with outstanding 0.12um resolution and accurate three-dimensional measurement capability. Magnification power from 120x to 14,400x satisfies the needs of researchers working between the limits of conventional optical microscopes and scanning electron microscopes (SEMs). (read more)

Precision molded glass aspheric lenses are a practical compromise between a multi-element lens and a molded plastic lens. A molded glass aspheric lens has two advantages over a multi-element lens; first, the aspheric design reduces spherical aberration and coma in a single element; and second, with fewer optical surfaces required, overall light transmission is higher.
