This is a Plano-Concave lens, type N-BK7, with a diameter of 10 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -16 mm, making it a negative or diverging lens. The lens is designed to operate within the wavelength range of 450-700 nm, which covers the visible light spectrum.
The lens is made of N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and wide transparency range. The lens features a spherical shape, with a radius of curvature (R1) of -8.475 mm for the concave surface. The inner and outer radii are both 0 mm, indicating that the lens has a uniform thickness across its diameter.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, reducing reflections and improving transmission.
The lens is sourced from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's information, the lens is in stock and ready for immediate dispatch.
