PLCX-25.4-154.5-UV 25.4 mm Dia. UVFS Laser Grade Plano-Convex Lens; EFL=309.2mm Uncoated

The PLCX-25.4-154.5-UV is a Plano-Convex Spherical Lens, a high-quality optical component sourced from CVI Laser Optics. This lens, with a catalog number PLCX-25.4-154.5-UV, is designed for use in laser applications and features a UVFS material (Mal-1965) with a diameter of 25.4 mm.

The lens's geometry is characterized by its plano-convex shape, where one side is flat (plano) and the other side is curved (convex). The curvature of the convex side has a radius of 154.5 mm. The lens's thickness varies from 3.5 mm at the edge to 4 mm at the center, providing a solid structure for efficient light transmission.

The effective focal length (EFL) of this lens is 309.2 mm, a critical specification that determines the lens's focusing power. This long EFL suggests that the lens is designed for applications requiring moderate magnification and a larger working distance.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a slightly lower transmission rate compared to coated lenses, it ensures a broader wavelength compatibility, making it suitable for use with a wide range of lasers, including those with a wavelength of 266 nm.

The lens's material, UVFS (Mal-1965), is a laser-grade material specifically designed for use in UV applications. It offers excellent transparency, high damage threshold, and excellent chemical resistance, making it an ideal choice for demanding laser applications.
