45-018 12.0mm Dia. x -48 FL; Uncoated; Plano-Concave Lens
The 45-018 is a plano-concave lens with a 12.0mm diameter and a focal length of -48.0mm, sourced from Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens's geometry includes a thickness of 4.12mm at the edge and 3.5mm at the center. The inner and outer radii are both 0mm, indicating a flat surface on one side and a curved surface on the other. The back focal length (BFL) is -50.31mm, and the radius of curvature (R1) is -24.81mm.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is designed to work optimally with a wavelength of 587.6nm.
This lens is suitable for various applications that require a concave lens, such as in cameras, projectors, or other optical systems. However, due to its uncoated nature, it may not perform as well in harsh environments or when high light intensity is involved. Therefore, it is essential to consider the specific requirements of your application before choosing this lens.
