37-803 12.7mm Dia. x 40.0mm FL; Uncoated; Plano-Convex Lens

The 37-803 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 40.0mm, making it suitable for a wide range of optical applications. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 587.6nm, which is the wavelength used for its specifications. The lens's geometry includes a thickness of 1.3mm at the edge and 2.3mm at the center, providing a balanced structure for efficient light transmission.

The 37-803 lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. This can be advantageous in certain applications where specific coating properties are not required. However, it's important to note that uncoated lenses can have higher reflectivity, which may affect the overall system performance.

The lens's base shape is circular, and its shape is spherical, which is a common geometry for optical lenses due to its ease of manufacturing and good optical performance. The lens's inner and outer radii are both 0, indicating a plano surface on one side and a curved surface on the other.
