  • LightMachinery Laser and Optics Library
  •  
    The internet is full of information but finding good solid information can be very difficult. We have collected information from our own staff of experts and also bookmarked information on the web that is reliable and we can use on a daily basis. Please let us know if you have any suggestions and enjoy our library.

  • The Universal Beam Splitter.
  • behaves like a very low loss non-polarizing beam splitter cube with the added benefit that the reflectivity of the beam splitter can be adjusted from 1% to 90% for any wavelength. As the UBS is rotated, the transmitted and reflected beams remain at 90 degrees. A simple marvel of optical engineering.

    Found by Jonathan, we'll order two versions to try, this replaces the PDLD system, a better system uses a circulator, which is much more expensive.

A Robust Uniaxial Force Sensor for Minimally Invasive Surgery - 0 views

  • miniature uniaxial force sensor for use within a beating heart during mitral valve annuloplasty
  • provides a hollow core to pass instrumentation
  • Fiber optic transduction eliminates electrical circuitry within the heart, and acetal components minimize ultrasound-imaging artifacts
  • ...4 more annotations...
  • 0–4-N force range
  • errors of 0.13 N (<3.2%)
  • MINIMALLY invasive surgery (MIS)
  • surgeons lose the critical sense of touch during MIS because instruments are passed through ports that mask the surgeon's feel of the internal operating environment.
