Wavelength Photoelectric Large Format 1064nm Telecentric Scanning Lens Laser Welding Cutting Marking Field Mirror

Telecentric F-Theta Lens - Optical Glass (TSL)

The telecentric F-Theta lens is a special type of lens system whereby the deflected off-axis laser beam can be focused vertically on the workpiece like a coaxially focused beam of light. The advantage of the telecentric scanning lens is its ability to flatten the field curvature to minimum distortion while providing excellent light spot quality throughout the scanning field.

The outgoing light of the telecentric field mirror is always perpendicular to the working surface, and the size of the focused light spot in the entire format is the same, which is often used in precision cutting, marking and other applications; distortion < 1%, telecentricity < 4 °

Telecentric F-Theta Lens - Fused Silica (TSL-Q)

For high-power lasers and ultrafast laser sources, we offer the TSL-Q series telecentric F-Theta lenses to minimize thermal lensing and focal length shift.
