G063892329 25.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm 1064nm

This is a G063892329 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens boasts a 25.4 mm diameter and a center thickness of 1.5 mm, making it a robust and durable choice for various applications.

The lens is a double-concave spherical lens, designed with a negative focal length (EFL) of -50mm. This design is particularly useful in imaging systems where a reduced image size is required. The lens's concave-concave base shape is circular, ensuring a wide field of view and minimal distortion.

The lens is made from N-BK7 Schott glass, a popular material in optical systems due to its excellent optical properties and high damage threshold. This material is known for its low auto-fluorescence, making it suitable for use in laser applications.

The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, particularly at the 1064nm wavelength. This coating ensures optimal performance in laser applications.

The item data also indicates that this lens is mounted, suggesting that it is ready for immediate use in optical systems. The web link provided in the item data indicates that this lens is currently in stock, making it a readily available option for users.
