45-087 12mm Dia. x 30mm FL Uncoated; Double-Convex Lens
The 45-087 is a 12mm diameter, double-convex lens with a 30mm focal length, sourced from the renowned optical component vendor, Edmund Optics. This lens, designed for general-purpose use, is uncoated, offering a simple yet effective solution for various optical applications.
The lens's base shape is circular, and it features a double-convex geometry, characterized by two spherical surfaces that curve outwards. This design allows for a wide range of applications, including imaging, illumination, and beam shaping. The lens's diameter is 12mm, and it has an edge thickness of 2.5mm and a center thickness of 3.7mm, providing a robust and compact structure.
The 45-087 lens is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmission in the visible spectrum, making it suitable for applications where light transmission is critical. The lens's effective focal length (EFL) is 30mm, and the back focal length (BFL) is 28.75mm, providing a long focal length that can capture detailed images from a distance.
The lens's surface radii are 30.36mm for the first surface and -30.36mm for the second surface, which are symmetrically curved to provide a uniform optical path. The lens's design is spherical, ensuring a smooth and continuous curvature, which is beneficial for reducing spherical aberration.
Please note that the lens is uncoated, which means it does not have any anti-reflective or protective coatings. While this may result in a higher reflectivity at the air-glass interfaces, it also means the lens is more cost-effective and suitable for applications where such coatings are not required.
In conclusion, the 45-087 12mm Dia. x 30mm FL Uncoated; Double-Convex Lens is a versatile and high-quality optical component, ideal for various applications. Its simple design, robust construction, and high-quality material make it a reliable choice for users seeking an effective and affordable optical solution.
