111-0144E 12.7 mm Dia. x 300 mm FL; Uncoated; Double-Convex Lens by EKSMA Optics

The 111-0144E is a high-quality spherical lens, specifically designed for applications requiring a convex-convex lens shape. Manufactured by EKSMA Optics, a leading global provider of optical components, this lens boasts impressive specifications and features.

The lens is made from the renowned material BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transparency. This makes it suitable for a wide range of applications, from imaging and metrology to beam shaping and focusing.

The lens has a diameter of 12.7 mm and a center thickness of 2 mm, ensuring robustness and durability. The edge thickness is 1.9 mm, providing additional structural integrity. The effective focal length (EFL) of this lens is 300 mm, making it ideal for applications requiring long focal lengths.

The lens's geometry is characterized by its double-convex shape, with radii of curvature R1 and R2 being 310.9 mm and -310.9 mm, respectively. This shape allows for superior light gathering and focusing capabilities. The lens has no inner or outer radius, indicating a uniform curvature throughout.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means the lens can be used in a broader range of wavelengths, as coatings often have specific spectral ranges.

In conclusion, the 111-0144E 12.7 mm Dia. x 300 mm FL; Uncoated; Double-Convex Lens by EKSMA Optics is a versatile and high-performing optical component, ideal for various applications. Its robust construction, excellent optical properties, and wide spectral range make it a valuable addition to any optical system.
