G311207331 22.4 mm Dia. UVFS Double-Convex Lens; EFL=30mm
This is the G311207331 22.4 mm Dia. UVFS Double-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. This lens, with a clear aperture of 22.4 mm, is designed for use in systems with a wavelength of 355 nm.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is characterized by its refractive power, which bends light rays towards the optical axis to provide a focused image. The first surface has a radius of curvature of 29.007 mm, while the second surface has a radius of -29.007 mm, indicating a concave shape.
The lens has an effective focal length (EFL) of 30 mm, which is the distance from the lens's secondary focal point to its optical center. This measurement is crucial in determining the lens's magnification power and field of view.
The lens is made from UVFS, a type of fused silica known for its excellent optical properties and durability. It has a central thickness of 6 mm and an edge thickness of 1.5 mm, providing structural rigidity while minimizing optical distortions.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections, enhancing the lens's light transmission and improving overall system performance.
