L-BCX149 30 mm Dia. Double-Convex Lens; EFL=200mm Uncoated

The L-BCX149 is a 30 mm diameter double-convex lens, sourced from the renowned optical component vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high degree of focusing power. The lens is circular, making it compatible with a wide range of optical systems and applications.

The lens's geometry is meticulously crafted, with a thickness of 2 mm at the edge and 3.1 mm at the center, providing a balanced structure that can withstand typical optical stresses. The effective focal length (EFL) of this lens is 200mm, making it suitable for medium to long-range optical applications.

The L-BCX149 is made from the high-quality material n-bk7 schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transmission across the visible spectrum. The lens is designed to work optimally at a wavelength of 587.6 nm, which falls within the green region of the visible light spectrum.

Notably, this lens is uncoated. While coatings can enhance certain optical properties, such as reducing surface reflections or protecting the lens from environmental factors, an uncoated lens can offer advantages in terms of cost, simplicity, and compatibility with various optical systems.
