45-933 2.00 mm Dia. N-BK7 Half-Ball Lenses Uncoated

The 45-933 is a 2.00 mm diameter N-BK7 Half-Ball Lens, uncoated, available from Edmund Optics. This lens, designed for use in optical systems, boasts a circular base shape and a half-ball geometry, making it suitable for a variety of applications.

The lens is made from N-BK7, a popular borosilicate crown glass known for its excellent optical properties. This material is characterized by a low refractive index and low dispersion, making it an ideal choice for broadband and achromatic applications. The N-BK7 Schott designation ensures high-quality glass, consistent with industry standards.

The lens has a diameter of 2.00 mm and a thickness of 1.00 mm, providing a compact and efficient solution for optical systems. The half-ball shape, with an inner radius of 1.00 mm, allows for precise light control and focusing. The uncoated surface ensures high light transmission but may result in increased reflection and reduced durability compared to coated alternatives.

This lens is designed to operate at a wavelength of 587.6 nm, making it suitable for use in a wide range of applications, from imaging to laser systems. The uncoated nature of the lens makes it suitable for use in systems where low cost and simplicity are prioritized over durability and performance.
