Infrared Optics: ALON and spinel excel as infrared optical materials ALON and spinel, two transparent ceramics used in IR optics, each exhibit a unique combination of properties; a comparison allows the optical engineer to select the right material for the job.
VCSEL ARRAYS: High-power VCSELs mature into production Certain qualities that include high reliability and spectral stability, high-temperature operation, simpler packaging and lower cost provide the advantage to VCSEL arrays when it comes to laser-pumping and replacement of flashlamps, illumination, and other applications.
