Contributions Of Holography To The Advancement Of Interferometric Measurements Of Surface Topography
Did Denis Gabor build the first all-optical computer for processing interference fringe patterns? Was Isaac Newton the first to create a synthetic off-axis hologram? Is my white-light 3D profiler actually a digital holography system? These are some of the questions addressed in this paper, which considers the many contributions of holography to the advancement of interferometry for surface topography measurement.  Continue Reading..

Measuring Broadband UVA And Violet LED Light Sources For Industrial And Medical Applications
Efficient utilization of UV radiation requires good measurement tools, but accurate light measurement in this spectral range presents challenges, such as how to accurately measure the irradiance if the wavelength of the light is not known.   Continue Reading..

TEST & MEASUREMENT SOLUTIONS

Zygo's Verifire™ MST provides high precision measurements of surface form and transmitted wavefront of optical components and lens systems. It is the only commercial interferometer system that can measure multiple surfaces simultaneously, maintaining relative surface information and providing quick and simple results from multiple surfaces.

Gentec-EO introduces the HP15KW-TUBE, a high-power detector for laser power measurement up to 15,000 W. This detector, a high-power water-cooled meter, is less sensitive to variations in water cooling temperature than other comparable products in the market.

BaySpec introduces Breeze-L™, the world’s smartest palm-held spectrometer in the Short-Wave Infrared (SWIR), with the longest wavelength coverage up to 2500 nm. Featuring proprietary miniaturized optics, the Breeze-L™ with its extended wavelength range of 1350-2500 nm, is highly efficient for maximum sensitivity with ultrafast acquisitions. For the first time, a smart spectrometer delivers close to laboratory performance in a palm-held form.

Zygo’s Nexview™ LS650 is a large format metrology system designed as an inspection tool for automated measurement of injection molding tooling, PCBs, glass panels, and other samples requiring an extended work volume up to 650 x 650 mm. It provides 2D and 3D measurements of a variety of surface features with sub-nanometer vertical precision and sub-micron lateral precision.

Ophir's Ariel is a self-contained, ultra-compact laser power meter for measuring high-power industrial lasers up to 8 KW. Designed for OEM and end-user applications in closed and confined spaces, such as additive manufacturing, metal cutting, and welding, the Ariel is a robust, battery-powered device that requires no water or fan cooling and is small enough to fit in the palm of a hand.

TEST & MEASUREMENT VIDEOS

  • Average power measurement of a pulsed laser can be a really tricky thing. What is the minimum repetition rate to get stable and reliable measurements? Myriam Blanchet of Gentec-EO answers this question in this video.

  • Myriam Blanchet of Gentec-EO explains the difference between a thermopile and a photodetector. She then gives you some tips to know which technology is best for your laser power measurements.

  • Félicien Legrand with Gentec-EO met with us on the second day of Photonics West 2022 to explain why your time is better spent developing improved laser processes when compared to the time invested in setting up laser beam diagnostic tools. He also gave us a brief introduction to the new Miro Altitude – a laser power display and energy device ideal for even the most demanding applications.

  • Learn how to use the Ariel, Ophir’s new ultra-compact "All in One" sensor for measuring high power industrial lasers up to 8KW.

  • The Ariel is an ultra-compact laser power meter designed for OEM and end-user applications in closed and confined spaces, such as additive manufacturing, metal cutting, and welding. This all-in-one power meter is battery-powered and requires no water or fan cooling. Able to fit in the palm of your hand, the system measures laser powers from 200mW to 8KW, and at a wide range of wavelengths, including 440-550nm green and blue lasers.

  • The second generation of the INTEGRA is a meterless line of all-in-one detectors that combine a detector and a meter in one device that lugs directly into your PC. Each detector of the INTEGRA series offers the same incredible performance as the usual detector and meter combination, from pW to kW and from fJ to J. For a brief introduction on this product, watch the video.

  • The BEAMAGE-4M is a beam profiling camera designed for accurate profile measurements of very small beams. The camera utilizes a USB 3.0 for the transfer rates up to 10X faster than regular USB 2.0 connections. Check out the video for a brief introduction.
