    • 665nm (655 to 675nm)
    • 850nm  (830 to 860nm)
    • Optical mouse for computers
    • Optical sensors

    From both offices in Canada and Taiwan (R.O.C.) Allied Scientific Pro offers high quality and cost effective VCSEL products and large production capacity: Following wavelengths are available single and multimode:  

    • 665nm (655 to 675nm)
    • 850nm  (830 to 860nm)

      Available in TO-46, Piranha-Single or Multi, Piranha-Flat Multi, Chip (High Power) Typical applications of VCSELs are:

    • Optical mouse for computers
    • Optical sensors
    • Optical encoders

      VCSELs have high performance and low cost advantages.  The key features are:

    • The structure can be integrated in two-dimensional array configuration.
    • Low threshold currents enable high-density arrays.
    • Surface-normal emission and nearly identical to the photo detector geometry give easy alignment and packaging.
    • Circular and low divergence output beams eliminate the need for corrective optics.
    • Passive versus active fiber alignment, combined with high fiber-coupling efficiency.
    • Low-cost potential because the devices are completed and tested at the wafer level.
    • Lower temperature-sensitivity compared to edge-emitting laser diodes.
    • High transmission speed with low power consumption.
