Abstract: Excitation used to produce luminescence is cancelled using interference with an excitation cancelling beam by controlling or setting a phase difference. An excitation beam and an excitation cancelling beam are produced from a common source and the excitation beam directed quantum light emitter to produce luminescence. A residual excitation beam and the excitation cancelling beam are coupled to interfere destructively so that the luminescence is available for detection or otherwise without substantial portions of the excitation beam.

Abstract: A laser absorptivity measurement device uses a linearly polarized incident beam, an optical configuration comprising an internal polarizing beamsplitter that transmits the linearly polarized incident beam and a quarter-wave plate that converts linearly polarized incident beam into a circularly polarized incident beam that is reflected off a processing substrate. The quarter-wave plate and polarizing beamsplitter can then direct the reflected light back into an integrating volume, where the power of the reflected light can be measured by a photodetector. The laser absorptivity measurement device is capable of making real-time absorption efficiency measurements of a variety of laser-based processes, including laser welding and brazing, additive manufacturing, and laser marking.

Abstract: A device comprises a platform constructed and arranged to be mounted to one or more solar array modules and one or more solar irradiance sensors on the platform configured to receive incident solar energy, the one or more solar irradiance sensors oriented on the platform so that the received incident solar energy is comparable to that received by the solar array modules, the one or more solar irradiance sensors providing solar irradiance signals in response to the incident solar energy. A processor is on the platform, the processor configured to receive the solar irradiance signals and, in response, generating a performance reference metric based on the solar irradiance signals, the performance reference metric related to the expected performance of the one or more solar array modules to which the platform is mounted. A transmitter is on the platform, the transmitter configured to periodically transmit the performance reference metric to a receiver.

Abstract: A system, apparatus and method of improved measurement of the SPF factor of sunscreen compositions. In one embodiment, a method of measuring the protection of a sunscreen composition includes exposing skin to a known intensity of light, measuring the amount of remitted light from the skin, applying sunscreen to the skin, exposing the skin to which the sunscreen has been applied the known intensity of emitted light of the spectrum of light from which the sunscreen is intended to protect the skin, measuring the amount of light remitted from the skin, and calculating a UltraViolet-A Protection Factor (UVA-PF) of the sunscreen by comparing the amount of light remitted from the skin with the sunscreen to the amount of light remitted from the skin without the sunscreen.

Abstract: Light detection devices and related methods are provided. The devices may comprise a reaction structure for containing a reaction solution with a relatively high or low pH and a plurality of reaction sites that generate light emissions. The devices may comprise a device base comprising a plurality of light sensors, device circuitry coupled to the light sensors, and a plurality of light guides that block excitation light but permit the light emissions to pass to a light sensor. The device base may also include a shield layer extending about each light guide between each light guide and the device circuitry, and a protection layer that is chemically inert with respect to the reaction solution extending about each light guide between each light guide and the shield layer. The protection layer prevents reaction solution that passes through the reaction structure and the light guide from interacting with the device circuitry.
