Product Description
Fiber Laser Plano-Concave Diverging Lens
Eternal Optics manufactures precision Fiber Laser Plano-Concave Diverging Lenses designed for fiber laser beam expansion, beam shaping, and optical path control applications. Optimized for common fiber laser wavelengths including 1030 nm, 1064 nm, and 1070 nm, our plano-concave lenses provide accurate beam divergence control, excellent optical performance, and reliable stability for industrial laser systems.
A Plano-Concave Diverging Lens is a negative focal length lens designed to spread and expand incoming laser beams. When integrated with other optical components, it helps adjust beam diameter, improve beam propagation, and optimize laser system performance. Our lenses are widely used in fiber laser optical assemblies, beam expanders, and custom laser delivery systems.
Manufactured from high-quality optical materials with advanced anti-reflective (AR) coatings, our Fiber Laser Diverging Lenses offer high transmission, low absorption, excellent surface quality, and strong laser damage resistance for 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.
