Fiber Laser 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. 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.

It is very useful for online inspection systems where the operator does not need to have offline inspection on the work piece.

Fiber Laser Collimating Lens

CO₂ Laser Telecentric Scan Lens

Telecentric scanning lenses are special configurations in which the arrangement of optics is designed to focus down the beam so that it is always perpendicular to the flat field. This is accomplished by ensuring that the system 'stop' is located at the front focal point of the lens system. The 'stop' is located at the position where the beam is deflected from the axis. In a single-axis scanning system, this location is at the scanning mirror. For two-axis scanning, the stop is mid -way between the mirrors. Adaptors for major scan head providers are available upon request.

CO₂ Laser Singlet F-Theta Scan Lens

Scanning Mirror for Others

Scanning mirrors are light weight rectangular mirrors used for high speed two-axis laser scanning systems. The dimen- sions for each mirror are calculated accordingly with the laser beam size. The mirror is designed with high reflectivity of 99.5% or above. The scanning mirror is generally mounted onto a galvanometer for scanning purposes. For two axis scan mirrors, commonly the Y mirror has a bigger size compared to the X mirror. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly.

Reflecting Mirror for Others

Reflecting mirrors are used either within a laser cavity as rear or folding mirrors, or external to the laser as bending mirrors to deliver the beam to the work.
