Latest Patents

One of Valois's latest patents is the **Symmetric Micro-Optic Module**. This micro-optic module couples a pair of substrates to opposing sides of a fast-axis collimating lens and a beam twister. The arrangement of optical elements is oriented substantially parallel to a neutral plane defined by the propagation paths of the light from each emitter of an array of laser emitters. The pair of substrates may have substantially the same coefficient of thermal expansion and coefficient of thermal conductivity. The micro-optic module is configured to exhibit symmetry of thermal loading about the neutral plane when the array of laser emitters emits light at an operational power level. This module may be coupled with an array of laser emitters, such as a laser diode bar. It exhibits thermal properties that facilitate a consistently focused light beam with minimal positional drift, enabling efficient and reliable coupling of the light beam to optical fibers and other high-tolerance applications.

Another significant invention is the **Rotary Flexure Bearing**. This rotary flexure bearing consists of concentric inner and outer hubs connected by compound flexure stages. These stages provide the angular compliance required for bearing rotation while maintaining a constant axis of rotation over the entire range of motion. This design offers large angular displacement, low operating stress, low operating torque, and high stiffness in the five noncompliant degrees of freedom. The rotary flexure bearing has applications in precision mechanics, particularly opto-mechanics. Specific applications include wafer and reticle alignment stages used in microlithography systems, mirror pointing and scanning mechanisms used in tactical and spaceborne systems, as well as flip-in mechanisms used in multiple field of view optical systems.
