Focusing Units

The focusing units bring the parallel beam from the collimating unit to a focused spot. The size of the spot and depth of focus is given by the combination of collimating and focusing optics. The focusing units exist both with a fixed focus position and as a z-adjustable unit, where the focal point position can be manually adjusted. The standard range of focusing units are prealigned and with synthetic fused silica optics for a precise result.
