G314002525 8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-8mm 725-1050nm
This is a Plano-Concave lens, type N-BK7, with a diameter of 8 mm and a center thickness of 1 mm. The effective focal length (EFL) of this lens is -8 mm, making it a negative or diverging lens. The lens is designed to operate within the wavelength range of 725-1050 nm, which makes it suitable for near-infrared (NIR) applications.
The lens is made of N-BK7 glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with Qio Bbar Arb2nirnbk7, a broadband anti-reflection coating that reduces surface reflections and increases transmission in the spectral range of 400-1100 nm.
The lens has a spherical shape, with a radius of curvature of -4.134 mm for the concave surface. The inner and outer radii are 0, indicating that the lens has a uniform thickness across its diameter.
This 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. For more details, please refer to the vendor's website provided in the item data.
