Source: Laser Components Understanding Infrared Emitters Understanding Infrared Emitters Thermal Emitters Thermal emitters are devices that emit thermal radiation from a heated source. They are commonly used in applications such as spectroscopy. Examples include incandescent lamps, Nernst lamps, and globars. Calibrated blackbody sources are also used, where a heated ceramic tube emits thermal radiation. Pulsable […]

One important case is that of a Lambertian scatterer, where the radiance of scattered light towards an observer remains constant regardless of the observation angle. This means that the scattering object appears equally bright

Source: LightTrans Understanding VCSEL Arrays: A Comprehensive Guide Introduction to VCSEL Arrays Vertical Cavity Surface-Emitting Lasers (VCSELs) are a type of laser diode that emits light perpendicular to the wafer surface. Unlike traditional edge-emitting semiconductor lasers, VCSELs can be fabricated in two-dimensional arrays on a semiconductor chip, allowing for higher combined output powers. These arrays
