Telecentric F-Theta Scan Lens for Diode Laser
When a vision system is being integrated into laser machining system, our achromatic telecentic scan lenses are colour- corrected between working wavelength and vision wavelength. The achromatic telecentric scan lens offers the benefits as same as the normal telecentic lens yet able to provide accurate vision positioning function. It is very useful for online inspection systems where the operator does not need to have offline inspection on the work piece.

F-Theta Scan Lens for Diode Laser
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. SLF Series F-Theta scan lenses are developed for input beam sizes less than 8mm, and they are compact with a common thread of M39x1.
