    Tech Spec PCX microlenses are made from LaSFN9 glass material with a 1.850 refractive index. Microlenses are made with diameters ranging from 1.5 to 2.5 mm and with effective focal lengths ranging from 1.0 to 2.5 mm. Fnumber values range from 0.67 to 1.0. The highquality surfaces have a low scratch/dig value of 20/10 that is suitable for demanding laser applications. These microlenses can be used to focus and collimate light in applications involving fiberoptics. Each microlens is coated with a
