Mini MASTER Overview
Mini MASTER workstations are tailored for specific applications. Intended primarily for Research and Development laboratories, Mini MASTERs offer excellent payback while keeping high performance.
Mini MASTER's are high payback laser micro machining workstations tailored for specific applications in Research and Development laboratories or small batch production.
Being smaller brothers of MASTER workstations, Mini MASTERs perform marking, cutting drilling, surface structuring and fit into reduced foot print.
Ultra short pulse lasers and SCA laser micro machining software complies to high requirements in solar cells applications, extra hard materials processing (like tungsten carbide), etc.
| Speed and spatial precision | Precision of laser micro machining is achieved by ultra-short laser pulses, state of the art Galvo Scanners and optics. In Mini MASTER workstations nano or pico second laser pulses cause minimal heat-affected zone and maximize spatial precision. High pulse repetition rate and adequate pulse energy ensure fast material removal during ablation or marking. Options of three different working wavelengths offer many machining possibilities for wide range of materials. | ||
Accuracy of positioning | Maximum firing accuracy and spatial resolution are achieved due to advanced beam delivery scheme. Fast galvoscanner for high throughput. |  | |
| Safety and robustness | Class 1 laser-safe and clean-room compatible enclosure ensures robustness and reliability. | ||
| Advanced control | Designed specifically for laser micro machining, SCA software provides automatic control of Mini MASTER workstation, easy design or import of patterns, flexible modification and simulation of micro machining process |  | |
