G314003331 10 mm Dia. N-BK7 Plano-Concave Lens; EFL=-10mm
This is a Plano-Concave Lens, sourced from Qioptiq Photonics, with a diameter of 10 mm and a center thickness of 1 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range.
The lens has a focal length (EFL) of -10 mm, indicating that it is a diverging lens, causing incoming light rays to spread out after passing through it. The radius of curvature (R1) is -5.168 mm, which is the radius of the curved surface of the lens. The inner and outer radii are both 0, suggesting that the lens has a flat outer surface.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces reflective losses at normal incidence and increases transmission, making the lens more efficient. The coating is designed for a wavelength of 588 nm.
The lens is spherical in shape, meaning that its curved surface is a portion of a sphere. This is a common shape for lenses due to its ease of manufacturing and good optical performance.
