Pre-Engineered F-Theta Lenses: Don’t have a complete design? No problem!
Our Pre-Engineered lenses give our customers the option of choosing suitable designs from a variety of our existing lenses based on their applications. We also offer custom F-Theta lenses. Just tell us your specifications (beam size, scan field diameter, wavelength range, etc.) and our team of expert engineers will optimize our preliminary designs to meet your exact needs. This will help you cut the product development lead time and also reduce or eliminate design fees!
F-Theta lenses are commonly used in laser scanning systems that require a flat image plane and high resolution. By introducing a specific amount of barrel distortion in the lens, the image height of the F-Theta lens is proportional to the scanning angle. These diffraction limited lens systems can be engineered to produce the desired spot size and have a distortion of less than 0.25% with the entire field of view.
