An optical device for dividing a beam into two or more separate beams. A simple beamsplitter may be a very thin sheet of glass inserted in the beam at an angle to divert a portion of the beam in a different direction. A more sophisticated type consists of two right-angle prisms cemented together at their hypotenuse faces. The cemented face of one prism is coated, before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of...

Correct Alignment Spells Success
Whether the job is splicing fibers together or connecting fibers to system devices, alignment is the key to success. This article explores the many ways to achieve that goal. Just as an electronic connector provides a pluggable connection between electronic circuits, a fiber optic connector provides an optical one. The goal is joining a fiber to a transmitter, receiver or another fiber with the lowest loss of optical power across the joint. Figure 1 shows a simplified example of fiber optic...
