G312259329 18 mm Dia. UVFS Plano-Convex Lens; EFL=30mm 1064nm
The G312259329 is a plano-convex lens with a diameter of 18 mm, designed for use in the ultraviolet, visible, and shortwave infrared regions of the spectrum. This lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens features a fused silica material (UVFS) with a high refractive index, making it suitable for a wide range of applications. The plano-convex design, where one side is flat and the other is curved, allows for efficient light concentration and minimal spherical aberration. The lens has an effective focal length (EFL) of 30 mm, providing a balance between field of view and focus.
The G312259329 is coated with Qioptiq's HP NBAR ARHS-YAG coating on both the front and back surfaces. This anti-reflection coating is specifically designed for use with YAG lasers at 1064 nm, reducing surface reflections and improving transmission.
The lens has a thickness of 1.5 mm at the edge and 4.4 mm at the center, providing structural rigidity while minimizing weight. The inner and outer radii are 0 mm, indicating a sharply curved lens surface.
