Aerotech has launched a 3D beam deflection system for laser micromachining. This thermally stable three-axis laser scanner is particularly suitable for high precision manufacturing of complex components for the medical, microelectronics and automotive industries. The AGV3D offers a rapid, flexible and

high-precision laser scanning solution featuring direct operation of dynamic linear tracking of the focusing optics with high resolution feedback. Positioning errors can be significantly minimised due to the high rigidity and accuracy of the linear module. With integrated water and air cooling, temperature gradients within the AGV3D are avoided, reducing errors caused by thermal drift. This results in consistent performance over the entire processing cycle, with high processing accuracy. The scanner housing is sealed and contains an air purge function to protect the optical components from contamination and reduce the risk of damage. The three-axis scanner offers two simple user-selectable configuration settings covering fields of view from 100 x 100mm to 1,000 x 1,000mm and above. It is available with different apertures for different beam diameters, and can be supplied as a fully-configured scanning system including flat field optics. The AGV3D is particularly suited to

applications where parts with variations in height or thickness are processed, or in multi-layer, additive processes. It is also well suited to applications where the working distance varies, or a larger field of view has to be achieved compared with F-Theta lenses. This includes additive manufacturing, 3D laser sintering, cylinder and tube processing, deep engraving and 3D laser micromachining and microstructuring.

Scancube IV

Scanlab’s latest scan system, Scancube IV, offers optional read-back functions for process monitoring. Compared to Scancube III, the system linearity has been improved by 30 per cent. The new housing design is both visually appealing and a functional element of the optimised heat management concept. The scan head can be optimally configured for various customer needs and is available with a 10 or 14mm aperture. Scancube IV can be configured using different tuning and mirror variants. In

SAFETY Orcatina

Lasermet’s new Orcatina safety curtains provide laser protection via a compact and neat curtain system that uses a pantograph structure in the folding mechanism. This guarantees a continuous and consistent pattern of folds that can be used not only to safeguard against laser radiation, but to act as a room separator and to minimise the sounds from the neighbouring partitioned room.

The folded laser blocking curtains use minimum space once drawn back. There are no floor rails, as the curtains are supported solely by the upper rail structure. The curtains are made from Lasermet’s Orca black and white laser blocking material, which is used on its conventional laser blocking curtains and laser blocking roller blinds, with consistent PEL ratings for

combination with an RTC control board, optional read-back functions for system monitoring and diagnostics are available. This means the actual position, temperature and other status values can be queried reliably during operation. The improved system linearity makes

calibration easier and enables more precise processing results. Also, the dust-tight housing provides optimised heat management and ensures the system always keeps a ‘cool head’, even during demanding applications.

different power densities and timescales. Ideal for wide installations, the Orcatina

curtains provide a neat result, while maintaining safety for personnel to the laser safety standard BS EN IEC 60825-4. In providing the necessary protection level, the curtains are designed as passive guards to enclose an area where Class 3B or Class 4 lasers are used. The curtains are designed to protect against accidental exposure to the laser beam, or for long-term blocking of laser radiation at lower power densities.
