Shunt Regulators
These are the standard reference voltage source widely used by the feedback circuits of switching power supplies. Compared to the Zener diode, which is a discrete product, a shunt regulator has much better voltage precision because voltage control is carried out as an IC.

Shunt Voltage References
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

Diode Lasers
Spot Creator
Advanced Photonic Sciences LLC
Spot Creator is an innovative accessory developed for enhancing the performance of blue laser diode based engraving and cutting machines. Spot Creator solves a major problem with using asymmetric blue laser diodes: the production of engraving features that are different in the X-Y directions, resulting in unequal or blurred lines. Using Spot Creator, line widths are equal in the X-Y directions, with a minimum spot of 50 μm. The intensity on the engraved part is thus maximized.
