L-BCX209 42 mm Dia. Double-Convex Lens; EFL=2000mm Uncoated
The L-BCX209 is a 42 mm diameter Double-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a Spherical Lens of the Convex-Convex subtype, featuring a Base Shape of Circular geometry.
The lens has a Center Thickness of 2.2 mm and an Edge Thickness of 2 mm, providing a robust structure. The Effective Focal Length (EFL) of this lens is an impressive 2000mm, making it suitable for applications requiring high magnification or long-distance focus.
The L-BCX209 is made from the high-quality material n-BK7 Schott. This material is known for its excellent optical properties, including high transparency and low auto-fluorescence, making it ideal for a wide range of optical applications.
The lens is designed to operate at a wavelength of 587.6 nm, which falls within the visible light spectrum. This makes it suitable for use in applications involving visible light, such as imaging, metrology, and beam manipulation.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
