erotech’s AGV3D is a new 3D beam deflection system for
laser micro-machining. The thermally stable three-axis laser scanner is suitable for high- precision manufacturing of complex components for the medical, microelectronics, and automotive
sectors, including additive manufacturing. 3D laser scan heads are ideal for
applications where flat-field objectives (f-? lenses) cannot be used or the contour of the workpiece requires focus tracking in the z-direction. Most 3D scanners
rapid, flexible and high-precision laser scanning solution featuring direct operation of dynamic linear tracking of the focusing optics with high-resolution feedback," explains Simon Smith, European director at Aerotec. Positioning errors can be significantly minimised due to the high rigidity and accuracy of the linear module.

The new pixxiLCD graphic displays from 4D Systems offer easy integration and feature a wide range of options. Available at Rutronik UK,4D LABS’- configurable PIXXI-28 or PIXXI-44 GPUs enable a variety of functions, including touch detection, microSD or serial flash memory, GPIO and ADC, with multiple millisecond timers, UART and I²C communication. The displays are offered in different
shapes and sizes, such as round (with 1.3’’) or rectangular versions with 2’’, 2.5’’ or 3.9’’. In addition, depending on the requirements of the application, there is a choice option between capacitive and non-touch displays. The pixxiLCD embedded graphic
displays have a standard 15-pin ribbon cable connector in 0.5mm pitch with ZIF socket interface, through which UART, I/O, I²C and the power supply with reset signals are led from/to the display. The 4D Workshop4 IDE developer software, which is compatible with all pixxiLCD displays, offers extensive programming options.

TWO NEW SERIES FOR HIGH FREQUENCY TESTING APPLICATIONS
Two new filter series from TTE Filters have been designed for high frequency testing applications. The new filters – LC17 and HC17 – provide brick wall characteristics and performance to 7GHz making them ideal for Audio-Digital-Conversion and Digital- Audio-Conversion (ADC/DAC) test set ups. Such signal conditioning testing is especially important for semiconductor chips and integrated circuits where testing frequencies continue to trend higher and higher (now in the GHz range). Relevant markets include commercial, industrial, medical, military/defence and test & measurement. TTE’s new filters leverage the steep roll-off response of Chebyshev topology in 17th
order lowpass (LC) and highpass (HC) designs to address the testing industry’s need for filters that can operate at GHz frequencies – much higher than traditional brick wall
anti-aliasing elliptical function filters which are typically limited to less than 500MHz. These new LC17 and HC17 filters, while not true brick wall filters, are designed in a way that their steep roll-offs closely resemble brick wall filters. Moreover, since TTE’s new filters are based on Chebyshev topology they have a slight ripple in the passband and no ripple in the stopband, unlike elliptical designs which have ripple in both the passband and stopband. Thus TTE’s filters provide desirable stopband performance at high frequency with limited passband ripple. The passband to stopband ratio for the LC17 filter is -50dBc at 1.19 fo and -60dBc at 1.27 fo. That ratio for the HC17 filter is -50dBc at 0.84 fo and -
60dBc at 0.78 fo. The frequency range for both filters is 1MHz to 7GHz. Standard or custom cases are available. The table below provides an overview of both series.
