Color Corrected F-Theta Lens, 163mm, 1030nm

• Ideal for Broad Spectral Laser Scanning Applications
• Diffraction Limited Across the Scan Field with Low Wavefront Error
• Long Working Distance and Large Scan Area

Color Corrected F-Theta Lenses are designed for use with material processing lasers that typically have relatively large chromatic bandwidths. Similar to an achromatic lens, these F-theta lenses ensure that each wavelength across a given broadband range is focused on the same focal plane and maintains the same scanning geometry, as opposed to a standard monochromatic F-theta lens. When used with galvanometers, beam expanders, and laser sources, these lenses provide flat fields at the image plane of scanning systems. Color Corrected F-Theta Lenses are ideal for a range of material processing and medical applications such as laser cutting, welding, drilling, confocal microscopy, and ophthalmology.
