The 84-241 is a Plano-Convex spherical lens, part of the extensive catalog offered by Edmund Optics. This lens boasts a 12.0mm diameter and a focal length of 18.0mm, making it suitable for a wide range of optical applications.
The lens is crafted from n-SF5 Schott, a high-quality material known for its excellent optical properties. The base shape is circular, and the lens features an inner radius of 0mm and an outer radius of 0mm. The edge thickness is 1.41mm, while the center thickness is 3mm, providing a solid and durable structure.
The 84-241 is coated with Edmund Optics' Laser V-Coat 1550, a specialized coating designed to enhance the lens' performance in the 1550nm wavelength range. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance and longevity.
The lens' geometry is precisely engineered, with a radius of curvature (R1) of 12.11mm and a back focal length (BFL) of 16.22mm. This results in an effective focal length (EFL) of 18mm, providing the user with a high degree of control over the optical system's focus and magnification.
