Thulium Fiber Laser (TFL) Beam Expander
The most common type beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam focus at the output. For low expansion ratios, the Galilean telescope is most often em- ployed due to simplicity, small package size and low cost. Beam expanders are commonly used to magnify the laser diameter that is to be focused back in a smaller spot size.

Thulium Fiber Laser (TFL) Telecentric F-Theta Scan Lens
Telecentric F-Theta Scan lens is a special type of lens system whereby the deflected off-axial laser beam can be per- pendicularly focused to work piece as similar to the on-axial focusing beam. The advantage of the telecentric scan lens is that it is able to flatten the field curvature to the least distortion and yet offering superb spot quality throughout the scan field. For high powered laser and ultrafast laser source, we offer TSL-Q Series Telecentric F-Theta Scan Lens to mini- mize thermal lensing and focal shift.

Thulium Fiber Laser (TFL) F-Theta Scan Lens
SL-Q Series F-Theta Scan Lenses are developed for ultra fast lasers with short pulse width and high pulse energy laser applications. These lenses are made with low dispersion Fused Silica with optical design to avoid back reflection and ghost image. When a vision system is being integrated into the laser machining system, our achromatic F-Theta scan lenses are colour-corrected between working wavelength and vision wavelength. They can provide accurate vision positioning function and it is very useful for online inspection systems where the operator does not need to have offline inspection on the work piece.
