F-Theta Scanning Lens

F-Theta Field Scanning Lens 1. F-theta mirrors are used in conjunction with oscillators for laser marking, welding, engraving, etc. 2. Commonly used field mirror lenses are plain optical glass, all-quartz and a mixture of both, depending on the power and pulse width of the input laser. All quartz field lenses are commonly used for high power laser and picosecond laser applications. 3. Uniform beam size over the full width, with aberrations <1%.
