  • Advantages of Semiconductor Laser Diodes Versus Helium Neon Gas Lasers

    Although HeNe gas lasers offer exceptional reliability and optical quality, users are quickly replacing them in their OEM applications with semiconductor laser diode technology. Laser diode modules offer many physical and electronic advantages over HeNe lasers. HeNe gas lasers provide superior

  • Fundamentals of Lasers

    of the presence of astigmatism (see Diodes vs. HeNe). The output power specified is the maximum power value of the laser light after the beam exits the laser housing; in other words, power is rated after passing through (but not before) any optics. Values stated are typically within +/-10%. The light

  • What Is a Ballast Resistor and Why Should I Use One?

    A ballast resistor is a mechanism placed in series with a HeNe gas laser anode. The unit works to promote a stable electrical discharge and to prevent the laser from oscillating. The rating of the ballast resistor must be high enough to stop the oscillation, yet low enough to prevent unnecessary

  • Helium-Neon Lasers

    A helium-neon (henceforth abbreviated HeNe) laser is basically a fancy neon sign with mirrors at both ends. Well, not quite, but really not much more than this at first glance (though the design and manufacturing issues which must be dealt with to achieve the desired beam characteristics, power

  • Understanding Spatial Filters

    Laser Objectives are designed for HeNe lasers (632.8nm) and provide the smallest spot sizes possible. Choosing the correct pinhole and objective combination will yield optimal results. The following equations were used to determine the values for the Aperture Selection Chart.

  • MICRO:Product Technology News (Oct '99)

    Matrix S200 metrology systems for CMP and etch provide application-specific sets of metrology techniques. The S200 CMP system has a 5 ' 10-mm-spot, 633-nm HeNe laser ellipsometer for measuring on-product substrate n and k and a 2.5-mm-spot, 470 905-nm reflectometer for measuring film thickness

SRP
Laser Cutting

SRP provides laser cutting services for projects where materials cannot be efficiently cut using a steel rule die. Unlike other die-cutting services, Laser cutting uses a focused beam to fabricate customer specified materials into custom shapes and sizes. Laser Cutting is ideal for applications where accuracy and speed are critical. It is also frequently used for quick initial prototyping. Benefits. Speed and Accuracy. Quick Initial prototyping. Can be used for heavy duty materials...
