Goniophotometer

Instrument Systems (Munich, Germany) recently launched with the LGS 650 goniophotometer, a new measuring system for solid-state lighting products and LED modules. Designed for samples up to max. 1300 mm diameter and 10 kg weight, the LGS 650 goniophotometer was developed for the analysis of angle-dependent spatial radiation properties. The test specimen is operated in a horizontal burning position and measurements can be taken at an angular range of ±160° in the gamma axis. The angular resolution of 0.01° enables very fine measuring grids recorded with a high level of accuracy and reproducibility.

The LGS 650 is compliant with all relevant specifications in conformity with CIE, DIN and IES standards. The probes may have a diameter up to max. 1300 mm and a maximum weight of 10 kg. Combined with a spectroradiometer, e.g. CAS 140D, from Instrument Systems, all spectral quantities such as color coordinates, color temperature and even color rendering index can be determined as a function of angle.

Safety Laser Scanner

The new safety laser scanner, PSENscan, from Pilz (Canton, MI) safely monitors up to three separate zones simultaneously, significantly increasing plant productivity. Up to four safety laser scanners can be connected in series in accordance with the master-slave principle, which reduces the cabling and set-up work considerably.

The safety laser scanner offers two-dimensional area monitoring with a large opening angle of 275°, so applications in which several adjoining sides of a machine or AGV are to be monitored can be implemented with fewer devices when compared with an 180° scanner. Up to three separate zones can be monitored simultaneously and up to 70 switchable configurations can be set up. The software tool PSENscan Configurator is used to configure PSENscan. The Ethernet port is used to connect PSENscan to the configuration computer.

Light Section Sensors

The SmartRunner Matcher from Pepperl+Fuchs (Twinsburg, OH) is a compact, camera-based light section sensor that combines both the evaluation process and the interfaces in one device. The device features specially preconfigured firmware that enables it to specialize in extremely precise profile comparisons. After initial setup and configuration-the user inputs the required reference profile using the teach-in mode and the Matcher captures an image of each object's line profile. Using LEDs and a 2D camera, the SmartRunner Matcher compares the current profile to the taught-in reference profile.

In addition to the Matcher, Pepperl+Fuchs also introduces the SmartRunner Detector. This light section sensor is optimized for high-precision monitoring, detecting even the smallest of faults. The Detector reliably identifies objects with a minimum size of 0.25 mm in a trapeze-shaped measuring range with a width of 350 mm at a maximum range of 700 mm. Since the SmartRunner Detector evaluates both the laser line on the object as well as the background, the sensor results are always reliable.

Field of View Video Measurement System

Vision Engineering (New Milford, CT) announced the availability of its new class of TVM Field of View (FOV) video measurement systems. The TVM series includes TVM20 and TVM35, with FOV sizes of 20 mm and 35 mm respectively. Both systems are designed to meet rigorous quality assurance applications in electronics, automotive, aerospace, medical and plastics manufacturing. The fixed stage FOV system enables instant, accurate measurements of small pressed metal components, turned parts, injection moulded plastics, tubes and cables, while the addition of a manually-controlled stage extends measurement for larger components up to 200 mm × 100 mm.

The combination of TVM's flat field telecentric lens and collimated sub-stage lighting, featuring a new quadrant LED ring light, creates a sharp image of components on the HD monitor and significantly improves video edge detection of complex parts such as threads and valves. TVM works in combination with new software features for instant measurement of wire insulation and screw threads. Cylindrical, flat, or square components can be measured on the shop floor, offering instant go/no go evaluation.

Laser Diode Driver

The ALPhANOV (Talence, France) laser diode driver range allows the users to get the best performance from their device while ensuring that it is protected at all times. The new product, called “Shaper,” completes this range by adding very high precision temporal pulse shaping capabilities between 500 ps and 2 μs with a repetition rate of up to 250 MHz, a temporal resolution of 500 ps and an intensity dynamic of 48 dB up to 2A.

The Shaper board includes a multifunctional synchronization unit with AWG (Arbitrary Waveform Generator), 3 built-in delay generators for synchronizing external instruments or other external laser amplifiers, and a TEC controller to regulate the temperature of the laser diode.

The driver is available in two versions: the “external modulation” version drives the laser diode with square waveforms and generates a shaping signal that is compatible with external devices such as acousto-optic or electro-optic modulators. The “direct modulation” version allows the pulse shape to be applied directly to the laser diode and a new functionality allows the user to remove spurious effects such as “gain switch” relaxation peaks.
