L-BCX187 38.1 mm Dia. Double-Convex Lens; EFL=500mm Uncoated

The L-BCX187 is a high-quality double-convex lens, part of the extensive catalog offered by Ross Optical. This lens, with a diameter of 38.1 mm, is designed for use in a variety of optical applications, thanks to its precise geometry and high-quality materials.

The lens features a large effective focal length (EFL) of 500mm, making it suitable for use in systems that require significant magnification or long-focus capabilities. The double-convex shape, characterized by two spherical surfaces that curve outwards, provides a wide field of view and low distortion, making it ideal for imaging applications.

The L-BCX187 is made from n-BK7 Schott glass, a material renowned for its excellent optical properties. This includes a high Abbe number, which ensures low chromatic aberration, and a high refractive index, which contributes to the lens's high EFL. The lens is uncoated, offering users the flexibility to apply their own coatings to suit their specific application requirements.

The lens's geometry is carefully crafted, with a thickness of 3mm at the edge and 3.7mm at the center. This ensures robustness while minimizing unnecessary weight. The inner and outer radii are 0, indicating a symmetrical lens design, which can simplify system integration and alignment.
