L-BCX202 42 mm Dia. Double-Convex Lens; EFL=150mm Uncoated

The L-BCX202 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 42 mm, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.

The lens features a large effective focal length (EFL) of 150mm, making it suitable for applications that require a longer focal length. The double-convex shape, characterized by two convex surfaces, provides a strong converging effect, focusing light to a single point. This shape is particularly useful in imaging systems, microscopy, and other applications where light needs to be concentrated.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent optical properties. This material ensures high transmittance across a wide spectrum, making the lens suitable for use with various wavelengths.

The geometry of the lens includes a thickness of 1.9mm at the edge and 4.8mm at the center. However, the inner and outer radii are not specified, indicating that they may be customized based on specific application requirements.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmittance, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
