Large Aperture UV Optical Lens 350-380nm BBAR Coating F720mm 360×360mm Applications

• Semiconductor Inspection

  Semiconductor manufacturing demands high precision in defect inspection. Featuring a large aperture (360 x 360 mm) and a long focal length (720 mm), this lens serves as a core optical component integrated into lithography systems. It enables the collection and projection of wide-area light beams, facilitates large-area scanning of large-format wafers, and supports long working distances, thereby improving wafer inspection yields.

• UV Laser Systems

  With high transmission in the UV spectrum, this lens utilizes UV-grade fused silica and a Broadband Anti-Reflective (BBAR) coating. It is suitable for beam delivery, expansion, or focusing in excimer and solid-state UV laser systems. As a large-aperture collimating and focusing lens, it enables precise focusing and long-range beam delivery, facilitating high-precision micromachining.

• Spectroscopic Analysis

  Applications such as Raman spectroscopy, fluorescence spectroscopy, and atmospheric environmental monitoring require high optical throughput and extremely low background noise. This large-aperture plano-convex lens collects more optical energy, serving as a condenser or collimator in spectrometers or monitoring equipment. Its UV BBAR coating minimizes reflection losses in the 350–380 nm range and eliminates stray light interference with spectral data.
