제품 설명
Fiber Laser Fused Silica Diverging Lens
Eternal Optics manufactures precision Fiber Laser Fused Silica Diverging Lenses designed for high-performance fiber laser beam expansion, beam shaping, and optical delivery systems. Optimized for 1030–1080 nm fiber laser wavelengths, including 1064 nm and 1070 nm laser systems, our fused silica diverging lenses provide excellent optical performance, high transmission, low absorption, and superior laser damage resistance.
A Fused Silica Diverging Lens is a negative focal length optical component used to expand and control laser beam divergence. When combined with collimating lenses, beam expanders, and other optical elements, it helps optimize beam diameter, improve beam propagation characteristics, and achieve precise laser beam control in industrial laser systems.
Manufactured from high-purity fused silica (quartz) with advanced AR (Anti-Reflective) coatings, our Fiber Laser Diverging Lenses offer excellent thermal stability, high power handling capability, and long operating lifetime under demanding laser environments.

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. 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.

Fiber Laser F-Theta Scan Lens
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. F-Theta lenses are commonly used in galvanometer scanning systems for laser marking, engraving and cutting; with the ability to deliver a focused spot to many points within a scanning field. We also supply lens adaptors for major scan head providers in the world. 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. When a vision system is being integrated into the laser machining system, our achromatic F-Theta scan lenses are colour-corrected between working wavelength and vision wavelength. They can provide accurate vision positioning function and it is very useful for online inspection systems where the operator does not need to have offline inspection on the work piece.
