L-PCX098 12.5 mm Dia. Plano-Convex Lens; EFL=30mm Uncoated

The L-PCX098 is a Plano-Convex lens with a diameter of 12.5 mm, sourced from the renowned optical vendor, Ross Optical. This lens is a part of their extensive catalog of simple lenses, specifically designed for applications requiring a convex lens with a flat surface.

The lens features an effective focal length (EFL) of 30mm, making it suitable for applications that require a moderate level of magnification or reduction. The EFL is a critical parameter in lens selection, as it directly influences the field of view and the size of the image produced.

The geometry of the lens includes a thickness of 1.5 mm at the edge and 2.8 mm at the center. This asymmetry is typical of Plano-Convex lenses, where the center thickness is greater than the edge thickness due to the curvature of the convex surface. The lens's base shape is circular, providing uniform optical performance in all directions.

The L-PCX098 is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. This material is particularly suitable for applications in the visible spectrum, as it has a high transmittance in this range.

The lens is uncoated, meaning it does not have any anti-reflective or protective coatings. While this may result in a higher level of reflection at the air-glass interfaces, it does not affect the lens's optical performance. However, for applications where light transmission and reduction of surface reflections are critical, a coated version of this lens may be more suitable.
