Teledyne's selection of high-quality components results in reduced EMI and lower start-up surges. The rugged design, including the direct-bond copper (DBC) and wirebond assembly, offers the most reliable and thermally efficient product on the market. Teledyne is also the world's innovative leader in manufacturing hermetically sealed solid-state and electromechanical relays. Teledyne Relays' industrial SSRs, mil-aero SSRs, electromechanical relays and coaxial switches offer switching solutions across a wide range of markets and applications.

In optics, laser beam divergence refers to how much a beam spreads over a distance. Imagine a cone where the tip is the theoretical origin of the laser beam (where the beam diameter would be punctual). If you measure the angle between two vectors, one going from the tip of the cone to the center of the base and the second going from the tip of the cone to the side of the base, the resulting angle is what you would call the divergence half-angle. Obviously, the full angle would be double that. Then, knowing three out of four parameters amongst initial diameter, final diameter, distance in between diameters and divergence angle, will give all the necessary information to calculate the fourth parameter. Also, if one understands the picture clearly, he will realize that the initial diameter can be, in fact, any diameter along the Z axis and doesn't need to be the one at the laser's exit.

Teledyne Relays has been providing industrial power solid-state relays for over 40 years. The company offers a broad range of products, from standard off-the-shelf single-, dual-, three- and quad-output relays to custom products with diagnostics and phase monitoring. These relays are used in numerous applications, including food equipment, heating, lighting, medical equipment, motor control, refrigeration, temp control and mil-aero applications.

As for all of our laser calculators, we assume that the beam is shaped as a perfect TEM₀₀ Gaussian beam and that the divergence is constant. This implies that we also assume that the two diameters are both inside the same homogenous, continuous and isotropic medium. Otherwise, divergence would be a function of space, therefore not constant. These equations can be used to calculate the laser beam diameters and divergence (half-angle).
