An optical device which divides an incident beam into two or more separate and distinct beams. A beamsplitter may be as simple as an uncoated plano-plano piece of glass inserted in a beam at an angle to divert a portion of the beam in a different direction. More complex beamsplitters employ coated and cemented right-angle prisms to separate colors.
SPHERICAL VS. ASPHERIC LENSES
HOW THEY’RE USED IN IMAGING APPLICATIONS
Optical Lenses are often categorized by their shape. Two common surface shapes are spherical and aspherical. Each offers unique characteristics that make it suitable for different use cases.
