This Product Selection Guide contains information to help select products in the F-Theta Lenses category on DigiKey.com
F-Theta Lenses are used in laser optic systems that are designed to focus on a planar image. These provide distortion to make the image height proportional to the focal length and scanning angle theta. These can be filtered by wavelength, lens material, focal length, beam diameter, and more.
SelectionCharacteristics
Wavelength: Typically this indicates the wavelengths of the light spectrum the device was designed for use with.
Lens Material: Indicates the material composition of the device.
Focal Length: The distance between the lens and the image plane.
Beam Diameter: The diameter of the maximum usable beam.
