Erbium 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.

Product Description
Erbium Fiber Laser Telecentric F-Theta Scan Lens
Eternal Optics manufactures high-precision Erbium Fiber Laser Telecentric F-Theta Scan Lenses designed for advanced 1550 nm fiber laser marking, scanning, and precision processing systems. Optimized for erbium-doped fiber lasers (EDFL) and eye-safe wavelength applications, our telecentric scan lenses deliver excellent beam positioning accuracy, low distortion, and consistent spot performance across the entire scanning field.
Our 1550nm Telecentric F-Theta Lenses are engineered to maintain a perpendicular laser beam incidence on the working surface, providing uniform spot size, improved marking quality, and enhanced processing accuracy. This makes them ideal for applications requiring precise laser scanning, stable energy distribution, and high optical performance.
Manufactured with premium optical materials and advanced AR (Anti-Reflective) coatings optimized for the 1550 nm wavelength, our Erbium Fiber Laser Scan Lenses provide high transmission, low optical absorption, excellent laser damage resistance, and reliable long-term operation.

Erbium Fiber Laser 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.
