The 45-934 is a 4.00 mm diameter N-BK7 Half-Ball Lens, uncoated, sourced from the renowned optical component vendor, Edmund Optics. This half-ball lens, also known as a meniscus lens, is characterized by its base shape being circular with a convex surface and a flat surface. The lens's geometry includes a diameter of 4 mm, a thickness of 2 mm, and an inner radius of 0 mm, while the outer radius remains unspecified.
The material of the lens is N-BK7, a type of borosilicate glass, which is known for its excellent optical properties, including a high refractive index and low dispersion. This specific lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is designed to operate at a wavelength of 587.6 nm, which is in the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam shaping, or light guiding.
Please note that the lens's coating is listed as an empty object in the item data, indicating that no specific coating details are provided. If you require a coated lens, we recommend checking with the vendor or looking for a similar product with the desired coating specifications.
