Fully Automated Beam Monitoring System

Ophir-Spiricon (North Logan, UT) has announced Ophir® BeamWatch® Integrated, a fully automated, non-contact laser measurement system designed to measure critical beam parameters in industrial production environments. BeamWatch Integrated is a patented, non-contact profiling system that captures and analyzes industrial lasers for wavelengths from 980nm - 1080nm and laser powers to 10 kW (30 kW, on request). The system provides real-time beam measurements of lasers that are typically too powerful for direct readings. Instead, it measures Rayleigh Scattering using a pass-through beam measurement technique that involves no contact between the instrument and the beam. Beam parameters measured include focus spot width and location, focal shift, centroid, M2, divergence, beam parameter product, Rayleigh length, beam tilt angle, and absolute power.

BeamWatch Integrated monitors high power YAG, fiber, and diode lasers in the 980-1080nm range. It charts all beam measurements over time in industrial material processing applications. High magnification optics measure beams with spot sizes down to less than 80 μm or less, allowing for smaller, more precise cuts with less waste of material.

Low Profile XY Stage

The AU200-100 × 100-SC (Solid Core) Stage is the newest addition to the expanding line of precision XY stages from OES (Optimal-Engineering Systems, Inc.) (Van Nuys, CA). The linear travel of the X and Y axes is 100 mm × 100 mm (3.937 in. × 3.937 in.) and the resolution of the X and Y axes is 20 microns (non-micro-step) or 1 micron (20 micro-steps per step motor driver in use), the typical repeatability is 2 microns, and the typical positional accuracy is 3 microns. A low profile XY stage measuring just 80 mm (3.150 in.) high with a compact footprint (including the motors) of 348 mm × 348 mm (13.701 in. × 13.701 in.).

Preloaded V-groove and crossed roller bearings and ground 4 mm per-turn lead screws having just 2 microns of backlash, all contribute to the high precision and stiffness of the AU200-100 × 100-SC Stage. The table of XY stage measures 300 mm × 300 mm (11.811 in × 11.811 in.) and has a precision pattern of 21 drilled and threaded mounting holes to easily add special tooling or fixtures, and for easy integration into new and existing applications. Additional tooling plates are also available for custom and interchangeable applications.

4-Channel Oscilloscope

Anritsu Company (Allen, TX) has introduced a 4-channel sampling oscilloscope option for its BERTWave™ MP2110A, creating a comprehensive single-instrument solution that integrates an oscilloscope and 100G BERT. With the option, the BERTWave can accurately evaluate the physical layer performance of 100G/400G optical transceiver modules, active optical cables (AOCs), direct attach cables (DAC), and high-speed optical devices used in data centers, core/metro networks, 4G/5G mobile backhaul, and 5G mobile fronthaul.

The BERTWave MP2110A, with the sampling oscilloscope option installed, supports various technologies, including NRZ/PAM4 signaling formats, as well as different wavelengths.

The built-in oscilloscope and BERT solution allows engineers to select 1, 2, or 4 channels, so it can be used during development and manufacturing of 100G/400G optical devices. The new sampling oscilloscope has best-in-class sensitivity supporting wide optical signal analysis from 25 Gbaud NRZ to 53 Gbaud PAM4 with a built-in clock recovery option.

Vertical Displacement Microscope

Titan Tool Supply, Inc., Buffalo, New York, announces the introduction of its new model ZDM-3 vertical displacement microscope to measure minute variations in height. The Z-Axis electronic depth measuring microscope features a built-in LED co-axial illuminator to allow the user to focus on the top or bottom of the part being inspected. The illuminator includes a green filter and is adjustable to control light, color, and intensity.

The new ZDM-3 is available with magnifications from 50 × to 400 × with a standard 10 × eyepiece and 100 × to 800 × magnifications with an optional 20 × eyepiece. Titan Tool states that the ZDM-3 can be fitted with a video adapter (Model TSTVA-12 available separately) to increase magnification range and to provide greater accuracy and ease of repeatability (from 0.0002-in. to 0.0003-in. or better). The use of the video adapter also relieves eye strain and allows for multi-viewing.

Camera with CoaXPress 2.0 Interface

With the Basler boost series, Basler (Ahrensburg, Germany) is one of the first camera manufacturers on the market to expand its portfolio with a camera featuring the CoaXPress 2.0 standard and modern CMOS sensor technology. The camera delivers high resolutions and high frame rates with a cable length of up to 40m. Basler also offers a combination of camera and matching interface card from a single source in the form of the Basler boost bundle.

Thanks to the upcoming CoaXPress 2.0 standard (or CXP 2.0), the Basler boost cameras achieve a maximum bandwidth of up to 12.5 Gbps with a single CXP cable. The precise triggering with the CXP cable eliminates the need for a separate I/O cable, making a single-cable solution possible in combination with power-over-CXP (PoCXP).

Basler combines this advancement in interface technology with the best which the current CMOS sensor landscape has to offer: an optional Sony IMX253 or IMX255 sensor delivers resolutions of 12 or 9 megapixels respectively with maximum frame rates of 68 fps or 93 fps.

Display Unit for Remote Spectral Detector

Gigahertz-Optik's CSS-45 Remote Spectral Detector can now be used with its new CSS-D display unit or operated by itself through PC connection under software control. Gigahertz-Optik's CSS-D Display Unit provides convenient handheld operation and control of a remote CSS-45 spectroradiometer head for the precise measurement of spectral irradiance (360-830nm), comprehensive photometric and colorimetric data as well as application specific data such as PAR PPFD.

The CSS-45 Remote Spectral Detector can be used directly connected to PC under its own supplied software control, connected to the CSS-D Display Unit as a self-contained light-color-PAR-spectral meter or CSS-D plus CSS-45 connected to PC using same software. An internal shutter normally found in the most advanced spectrometers automates dark level measurements, thereby facilitating accurate remote operation over extended periods.


500-Watt Blue Laser

NUBURU (Centennial, CO) announced the release of its new 500-Watt 450nm AO-500 industrial laser, bringing the power of blue light to deeper materials processing applications. Gold, aluminum, and copper are among the metals that absorb blue light much more than they do the infrared wavelengths of conventional industrial lasers. High power is only part of the story, however, because the efficiency and quality of materials processing applications are driven by power density. Increasing power density by a factor of four increases weld depth more than one-and-a-half times and increases the weld speed three to four times. The AO-500's beam parameter product is less than 30-mm-mrad, which enables rapid defect-free copper welding, and welding dissimilar metals with minimal formation of undesirable intermetallics in the joint.
