  • Lasers: Understanding the Basics

    This unique axis with very high optical gain becomes also the direction of propagation of the laser beam. A somewhat different example of a uniquely long (and flexible!) gain axis is the fiber laser. Figure 2. In the prototypical gas laser, the gain medium has a long, thin cylindrical shape. The cavity is …

    2020-8-17u2002·u2002Kailh Speed Silver is a Linear switch from the Kailh Speed series. The operating force of Kailh Speed switches is known to be on the lighter side at 40cN and increases to almost 80cN as you hit its total travel distance at 3.5mm. At 1.1mm, the switch activates. As you release the key, it resets at 1mm.

  • Lens Aberrations: Avoiding Defects in Imagery

    For on-axis light bundles, the optical axis of the lens coincides with the central ray in that bundle. For off-axis bundles, the corresponding central ray is called the chief ray, or principal ray. The height of the chief ray at the image plane defines image size. If lateral color exists in the lens system, this chief ray is dispersed, causing ...

  • Gaussian Beam Propagation

    The Rayleigh range of a Gaussian beam is defined as the value of z where the cross-sectional area of the beam is doubled. This occurs when w (z) has increased to √2 w 0. Using Equation 4, the Rayleigh range (z R) can be expressed as: (5) zR = πw2 0 λ z R = π w 0 2 λ. This allows w (z) to also be related to z R:

  • Camera Tracking System

    Despite using optical tracking, StarTracker is unique in that it is unaffected by studio lighting. This gives you complete freedom to install and adjust lights as needed. Ease of use. The initial set-up and calibration is quick and simple. Once you have applied the 'stars' to the ceiling, a major part of the installation is done.
