This is a Plano-Concave lens, type N-BK7, with a diameter of 10 mm and a center thickness of 1 mm. The effective focal length (EFL) of this lens is -10 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 transmission range. The lens has a spherical geometry, with a radius of curvature (R1) of -5.168 mm for the concave surface. The inner and outer radii are both 0 mm, indicating that the lens has a uniform thickness.
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, providing improved transmission and reduced reflection.
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 available for immediate purchase.
