KPC025 12.7 mm Dia. x -25 mm FL; Uncoated; Plano-Concave Lens
The KPC025 is a plano-concave lens with a diameter of 12.7 mm and a focal length of -25 mm, making it a negatively powered lens. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or to enhance its optical properties.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and wide transparency range. The lens's geometry includes a thickness of 3.83 mm at the edge and 2.5 mm at the center, providing a balanced structure for its size. The inner and outer radii are both 0, indicating a flat surface on both sides of the lens.
The lens's design is spherical, which is a common shape in optical elements due to its simplicity and versatility. The wavelength of 589 nm suggests that this lens is designed for use in the visible light spectrum.
