F-theta lenses and beam expanders

F-theta lenses have a laser spot position linearly proportional to the scan angle and are useful in many laser-scanning applications.

F-theta lenses are used at wavelengths across the optical spectrum. Covering wavelengths from the UV to the far-IR (from 266nm to 14µm). Designed to reduce the number of optical components needed to provide a flat image plane for scanning applications, these lenses deliver the same resolution and intensity across the image plane.

Beam expanders are designed to magnify a laser diameter efficiently and precisely. The range includes fixed focus, variable zoom, and motorised zoom options. Our beam expanders can be found in industrial material processing (drilling and welding of synthetic materials or cutting), medical and biotechnological applications (confocal microscopy and ophthalmology), science and research, laser markings, and laser displays.
