114-0106E 12.7 mm Dia. x -25 mm FL; Uncoated; Double-Concave Lens

The 114-0106E is a high-quality spherical lens, specifically designed for use in optical systems that require a concave-concave lens configuration. This lens is sourced from EKSMA Optics, a renowned vendor known for their extensive range of optical components.

The lens boasts a diameter of 12.7 mm and a center thickness of 2.2 mm, with an edge thickness of 3.2 mm, providing a robust and durable structure. The lens is designed with a double-concave geometry, featuring inner and outer radii of 0 mm, and a base shape that is circular. This geometry results in a focal length of -25 mm, making it suitable for applications that require a negative focal length.

The lens is crafted from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for a wide range of applications, particularly in the visible spectrum around the wavelength of 546 nm.

Notably, this lens is uncoated, offering users the flexibility to apply their own coatings based on their specific application requirements. However, it's important to note that uncoated lenses may have higher surface reflections, which could affect the overall performance of the optical system.
