All Facts for Choosing LED Optics Correctly
... It makes sense to use a reflector design, when the size of the light source is large and the light source consists of an array of dies under a common phosphor layer. Examples of such light sources are e.g. the most Citizen and Bridgelux LEDs. For these LEDs, making a lens would mean to design a huge ...

Introduction Reflection of Light
... Mirrors reflect all of the light that strikes them and form images. A plane, or flat, mirror forms virtual, life-sized images. A concave mirror forms either enlarged virtual images or reduced real images. A convex mirror forms only reduced virtual images. Refraction, or bending, of light occurs when ...

Interferometry
Interferometry is a family of techniques in which waves, usually electromagnetic, are superimposed in order to extract information about the waves. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, and velocimetry.Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities. In analytical science, interferometers are used in continuous wave Fourier transform spectroscopy to analyze light containing features of absorption or emission associated with a substance or mixture. An astronomical interferometer consists of two or more separate telescopes that combine their signals, offering a resolution equivalent to that of a telescope of diameter equal to the largest separation between its individual elements.
