UV Laser Air Spaced Focusing Lens

UV Laser Air Spaced Focusing Lens

Eternal Optics manufactures precision UV Laser Air Spaced Focusing Lenses designed for advanced 355nm and 266nm ultraviolet laser systems, delivering superior focusing accuracy, excellent thermal stability, and high-quality laser spot performance for precision processing applications.

An Air Spaced Focusing Lens uses a multi-element optical design with controlled air gaps between lens elements, allowing improved aberration correction and enhanced optical performance compared with conventional single-element or cemented lens designs. This structure provides better beam focusing quality and reliable operation under high-energy UV laser conditions.

Our UV Air Spaced Focusing Lenses are manufactured from high-purity UV Fused Silica (Fused Quartz) materials with wavelength-specific AR coatings optimized for ultraviolet laser wavelengths. These lenses provide high UV transmission, low absorption, high laser damage resistance, and stable optical performance for demanding industrial applications.
