Micro Machining

Micromachining Division supplies full turnkey laser micromachining systems for laser drilling, cutting, marking, patterning, milling, and ablation. A variety of configurations are offered which can incorporate DPSS nanosecond, picosecond or femtosecond lasers operating in the IR, visible and UV to give controlled ablation of a wide range of materials. Lasers standard systems range from tabletop general machining advanced research and development to high commercial production solutions.

LPS Series of laser system for reliable Laser Machining

A typical example of laser system integration is the LPS Series easy to use and compact to conserve valuable floorspace. Typical applications include silicon wafer coring/resizing, solar cell micromachining and cutting/drilling/grooving thin metals and ceramics for all sorts of applications including medical.

Important features of the LPS-300 system
1. Through-the-Lens Viewing:

The LPS-300 features video viewing for a magnified image of work in progress. A video camera looks through the laser focusing lens – a similar principle to an SLR camera or a rifle scope. It simplifies and speeds up alignment of each part, facilitates high yields, and targets laser impact. But most important – it provides both sharp visual human focus and sharp laser beam focus which otherwise would be at different places because of chromatic aberration. Magnification is 60X, twenty times more powerful than opera glasses.

2. Three-Axis Computer Controlled System

Our standard design is 3-axis which increases the versatility of the laser machine. Parts having different thicknesses can be rapidly inserted in the machine.

3. Computer Controlled Focal Point

A method of rapid and reliable control of laser spot size is by the computer driving the motorized beam expanding telescope. This works by placing the laser focus quickly at desired distances above and below the top surface of the part, which does not change the operator's visual plane of focus so the part remains in sharp focus to the human eye.

Laserod system components & options - OVERVIEW(statement of capabilities)

We integrate lasers, motion devices, computer hardware, power distribution drawer or box, software and optics into a fully functional laser machining tool. It goes without saying that "Know How" is our stock in trade.

We suggest you have us prototype first as proof of principle, then run lots to prove out performance, throughput, and quality.

List of Jobs Done by Solid-State Lasers:
  • IR medium power diode: all thin metals, some rubber and some plastics – also thin
  • Low power diode: IR, green or UV for display patterning, resistor trimming, marking, UV for 10um holes or patterns etched on coatings on glass or plastic substrates.
  • IR high power fiber: robust parts that the high pressure air won't blow away or damage such as silicon wafers, solar cells and ceramic substrate resizing at high speeds
  • IR low power fiber: patterning thin coatings on glass or plastic substrates at high speed
