Intro to Laser Management: Laser Profiling 101
Intro to Laser Management: Laser Profiling 101 As laser science and photonics have progressed throughout the years, so have the means for improved digital laser profiling techniques and measurement. Traditionally, laser operators only verify a laser’s average power or energy to improve efficiency and, if everything is in order, put their laser back into service. This article discusses key considerations and basic steps required to identify and use a camera profiling system (arrayed...  Continue Reading...
Reimaging UV Laser Beam Profiling Ophir-Spiricon offers three families of UV converter products designed for the indirect measurements of UV laser beam profiles. This application notes compares and contrasts each family, and covers their basic specifications and applications.  Continue Reading...
University Research Team Faces Challenges Of Measuring Multiple Lasers There are often times where several laser sources must be tested, validated, or qualified for a particular project. Unfortunately, by the time scientists realize that these measurements need to be made, the laser systems are typically already in place, the experiments are ready to be conducted, and any delays could be counterproductive. Therefore, laser measurement equipment needs to be cost effective, commercially available, easy to use, quick...  Continue Reading...
QPSI™ Vibration-Tolerant Interferometry
QPSI™ Vibration-Tolerant Interferometry Zygo’s QPSI technology eliminates the problem of environment vibrations with measurements that require no special setup or calibration. A ZYGO interferometer utilizing QPSI technology is capable of producing reliable high-precision measurements in the presence of environmental vibration from common sources such as motors, pumps, blowers, and personnel.  Continue Reading...
Coherent Artifact Reduction System (CARS)
Coherent Artifact Reduction System (CARS) Obstructing artifacts in interferometric data can come in many different forms, such as a “bulls-eye,” which can be caused by dust on an optical surfaced in the coherent beam path of an interferometer. These artifacts can print through on the height map and affect the magnitude and repeatability of the surface results. As a solution, ZYGO offers the Ring of FireTM extended source method for reducing noise and other artifacts.  Continue Reading...
Optical Profiling Of High Slope Surfaces
Optical Profiling Of High Slope Surfaces Optical profilers using Coherence Scanning Interferometry (CSI) have traditionally found it a challenge to measure highly sloped surfaces. Surfaces like these can be found in all industries and include optical micro-lenses, brightness enhancing structures, and machined cones. ZYGO offers CSI based profilers running Mx™ software with advancements in signal detection and processing that vastly improve the ability to obtain valid topography...  Continue Reading...
High Power Industrial Laser Applications: New Solutions To Old Problems
High Power Industrial Laser Applications: New Solutions To Old Problems High power laser systems are making their way into more and more industrial applications in order to produce results not previously practical. The advanced scalability, high beam quality, and wall-plug efficiency of fiber lasers in particular have made laser beams with powers of many tens of KW a common tool available for commercial use. Even processes requiring more modest power levels often use a high-power laser system and distribute the beam ...  Continue Reading...

  Fastest Multi-Wavelength Meter: 438 Series Fastest Multi-Wavelength Meter: 438 Series

The 438 Series Multi-Wavelength Meter is designed to take the fastest wavelength, power, and OSNR measurements (at 10 Hz) for the analysis of as many as 1000 discrete optical signals. This meter offers high efficiency, straightforward operation, and a rugged design for the most efficient WDM wavelength testing available, even in the most demanding applications.

Compact, All-In-One LED Luminaire Measurement System: FluxGage Compact, All-In-One LED Luminaire Measurement System: FluxGage

The FluxGage is Ophir’s new compact measuring system for LED Luminaires that measures their total flux, color (CCT, CRI, Duv, chromaticity), and flicker. The system measures the total flux using solar panels instead of an integrating sphere, delivering the same functionality in one third of the size. The gauge is capable of measuring any luminaire that fits into its opening.

Laser Beam Profilers Laser Beam Profilers

Laser beam profilers are the optimal solutions for increasing chances of success in the design or applications of new lasers, or when a laser system is no longer meeting the desired specifications. Ophir Photonics offers a wide range of beam profiler choices including CCD and CMOS cameras, scanning slit sensors, InGaAs and pyroelectric cameras, and pinhole and knife edge sensors.

Power Meters for Lasers and other Light Sources Power Meters for Lasers and other Light Sources

Ophir’s series of power meters are designed with the highest sensitivity, lowest noise, and most precise calibrations in order to bring out maximum performance levels from their smart sensors. These power meters and PC interfaces operate on the smart plug principle, meaning that these devices can work with nearly all Ophir sensors.

Energy Sensors Energy Sensors

Ophir Photonics presents a wide range of energy sensors, or pyroelectric sensors, designed to measure repetitive pulse energies and average powers at pulse rates up to 25000 pulses per second, and pulse widths up to 20ms. These sensors use a pyroelectric crystal that generates electric charges that are proportional to the pulse energy.

Power Sensors Power Sensors

Ophir Photonics presents a wide range of power sensors including thermal sensors, power/position/size sensors, thermopile discs, thermal surface absorbing sensors, and water cooled sensors. These devices feature very large dynamic power ranges, wavelengths, and thermal sensitivities.

Helios Laser Power Meter For Industrial Automation Helios Laser Power Meter For Industrial Automation

The Helios is a compact, precision laser power meter designed specifically for the measurement of high power lasers in industrial processing applications. It measures an array of high power solid state lasers such as diode, fiber, and YAG lasers with powers ranging from 100 W to 12 kW and energies ranging from 10 J to 10 kJ. This device operates by measuring the energy and exposure time of a short 0.1 to 10 second exposure of the laser, and then calculates the power.

Vibration-Tolerant Interferometry QPSI™ Technology Vibration-Tolerant Interferometry QPSI™ Technology

Precision interferometric metrology faces the challenge of environmental vibrations which can ruin countless precision measurements. Vibration affects measurement results and spatial frequency analysis, making it difficult to make high quality optics without reliable measurements. Zygo’s QPSI technology eliminates this problem with measurements that require no special setup or calibration, and cycle times are typically within a second or two of standard PSI measurements.
