  • What Does a Collimating Lens Do?
    Collimating is the process of aligning a light beam or stream of particles in a parallel direction. The process minimizes the spread of the particles, ensuring they propagate in a parallel fashion.

    length, their formation means they are ideally suited to applications that require focused, collected or collimated light
  • High Optical Speed Filters
    A principal limitation to the use of optical filters is that they are most effective when used in a collimated beam of light. This requires that for optimum performance the filter can not accept a wide field of view.
  • Correction Methods for Semiconductor Laser Diodes
    integrate a highly advanced microlens into a variety of our packages. Microlensing circularizes the naturally elliptical light output of a laser diode. The microlensed diode emits a circular, diffraction limited beam without the inclusion of correcting prisms and lenses. In addition, the extremely high
  • Advantages of Semiconductor Laser Diodes Versus Helium Neon Gas Lasers
    optical characteristics. While laser diodes must take advantage of external optics to yield a high quality output beam, HeNe output is well-collimated and does not require external optics. HeNe lasers also offer excellent coherence lengths (10cm to several meters), and most small tubes operate as single
