제품 설명
Erbium Fiber Laser F-Theta Scan Lens
Eternal Optics manufactures precision Erbium Fiber Laser F-Theta Scan Lenses designed for advanced 1550 nm fiber laser marking, engraving, scanning, and precision processing systems. Optimized for erbium-doped fiber lasers (EDFL) and eye-safe wavelength applications, our F-Theta lenses provide accurate laser beam positioning, excellent field flatness, low distortion, and consistent spot quality throughout the entire scanning area.
Our 1550nm F-Theta Scan Lenses are designed for use with galvanometer scanning systems, converting the angular movement of the scanner into a precise linear marking field. This enables high-speed and accurate laser processing while maintaining stable focus performance across the working area.
Manufactured using high-quality optical materials with advanced AR (Anti-Reflective) coatings optimized for the 1550 nm wavelength, our Erbium Fiber Laser Scan Lenses deliver high transmission, low optical absorption, excellent laser damage resistance, and reliable long-term performance.

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.

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.
