Abstract: The present application discloses an apparatus configured to measure characteristics of high power beams of laser energy used in material processing. In one embodiment, the apparatus includes a housing having a first compartment and a second compartment separated from each other to reduce the transfer of thermal energy between them. Optical modules having optical sensors configured to measure characteristics of the high power beam are mounted in the first compartment. An optical window operative to allow a significant portion of the beam to propagate therethrough is mounted in an intermediate housing member separating the first and second compartments. A removable and replaceable beam dump configured to absorb most of the high power beam is positioned in the second compartment. The removability/replaceability of the beam dump enables operation of the apparatus without active cooling of the beam dump assembly, simplifying the apparatus and protecting the optical sensors in the first compartment.

Abstract: The present application discloses an improved thermopile laser sensor apparatus and methods of use. In one embodiment, the apparatus includes a sensor body having a first sensor body recess and a second sensor body recess formed therein, with a substrate positioned in the first sensor body recess in thermal communication with the sensor body. The substrate includes at least one absorber attached thereto and configured to absorb a portion of a beam of laser energy. A first thermal sensor in thermal communication with the substrate and the sensor body may be formed on or attached to the substrate. A second thermal sensor in thermal communication with the sensor body may be positioned in the second sensor body recess. A thermal barrier configured to reduce the rate of transfer of thermal energy from the substrate to the second thermal sensor may be positioned between the substrate and the second thermal sensor.

Abstract: The present application discloses a zoom lens assembly having a first static lens group and a second static lens group defining an assembly optical axis secured to a lens support. A first guide member having a first guide member axis is secured to the lens support, and a second guide member having a second guide member axis is secured to the first guide member. A first mobile carriage is slidably coupled to the first guide member and a first mobile lens cell having a first optical axis is secured to the first mobile carriage. A second mobile carriage is slidably coupled to the first guide member, with a second mobile lens cell having a second optical axis secured to the second mobile carriage. The zoom lens assembly further includes a third mobile carriage slidably coupled to the second guide member, with a third mobile lens cell having a third optical axis secured to the third mobile carriage. The first guide member axis and the second guide member axis are substantially parallel, and the first optical axis, second optical axis, and the third optical axis are substantially collinear with the assembly optical axis.

Abstract: A photometric test system for LED luminaires. The system uses photodetective panels to detect and measure light. By placing an optical absorber layer with low reflectivity and low transmissivity over the photodetective panels, a detection surface which is also an absorber is achieved. This absorber reduces reflection of incident light from the device under test (DUT), and light reflected from the photodetective panels. A pinhole array can be conveniently used for this purpose. This enables the measurement area of the system to be essentially no larger than the emitting area of the DUT. A diffuser positioned between the absorber layer and the photodetective panels increases the accuracy of the system. Simulations and experimental results show that this system can measure total flux with an uncertainty of 4.3%. The demonstrated system is used in 2π geometry. The system measures total flux, color parameters (such as CCT, CRI, chromaticity) and flicker.
