Fast-axis Collimation (Aspherical Cylindrical lenses)

The most important optical component in the beam forming systems in high-power diode lasers is the fast-axis –collimation optic.The lenses are manufactured from high-q, uality glass and have an aspherical surface .Their high numerical aperture permits the entire diode output to be collimated with outstanding beam quality.The high transmission and excellent collimation characteristics guarantee the highest levels of beam forming efficiency for diode lasers.

Advantages

l          Aspheric cylindrical lens

l          High beam quality

l          High numerical aperture(NA 0.64-0.86)

l          Diffraction-limited collimation

l          High transmission

l          Long term stability
