Microspher / MS
Micro Spheres are mostly used for coupling optical fibers to laser diodes and other fibers or detectors.
Since these ball lenses are much smaller they are suitable for applications requiring reduction in size and weight. The lens circumference are completely polished and should be handled carefully to avoid damage.Both AR coated and uncoated are available. Single layer MgF2 is available in 3 variations of bandwidths 400 − 700nm, 700 − 900nm and 1300 − 1550nm.
Design wavelength of the focal lengths is 587.6nm (yellow helium line [d])
