Our lens systems include objectives for beam expansion, F-Theta lenses (i.e., scan lenses or lens systems for use in galvo systems), and achromatic lens systems.
Scan lenses used in Galvo systems
Scan lenses, also known as F-Theta lenses, are used in Galvo systems to keep the spot diameter in the working plane as small and as constant as possible.
This is obtained through a system of several lenses.
LASER COMPONENTS has a large selection of F-Theta lenses available that are designed for all common focal lengths and field sizes.
F-Theta Lenses for Nd:YAG Lasers
We also have F-Theta lenses for 532 nm, 355 nm, and 266 nm available upon request.
