14BCV40-1-1 25.4 mm Dia. x -40 mm FL; Uncoated; Double-Concave Lens

The 14BCV40-1-1 is a high-quality double-concave lens, sourced from the reputable vendor Standa. This lens is characterized by its concave-concave base shape and circular geometry, making it suitable for a wide range of optical applications.

The lens has a diameter of 25.4 mm, ensuring a substantial light-gathering area while maintaining a manageable size. The edge thickness is 6.1 mm, providing structural integrity and resistance to deformation. The center thickness, at 2.7 mm, contributes to the lens's overall compactness and ease of integration into optical systems.

The effective focal length (EFL) of this lens is -40 mm, indicating its double-concave nature. This negative focal length is crucial in designing and simulating optical systems that require image inversion or reduction.

The lens is made from n-BK7 Schott, a renowned optical glass known for its excellent optical properties and versatility. The wavelength of 546 nm suggests this lens is designed for use in the visible light spectrum.

Notably, this lens is uncoated. While coatings can enhance specific optical properties, such as reducing reflection or increasing transmission, an uncoated lens offers simplicity and cost-effectiveness. It is essential to consider the specific requirements of your optical system when deciding whether an uncoated lens is suitable.
