87-693 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=200mm Protected Gold 700-2000nm

The 87-693 is a 25 mm diameter Plano-Convex Spherical Mirror, sourced from the renowned optical component vendor, Edmund Optics. This mirror is designed with a convex geometry, featuring a 400 mm radius of curvature (ROC) and an effective focal length (EFL) of 200 mm, making it suitable for a wide range of optical applications.

The mirror is crafted from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material, often used in high-end optical systems, ensures minimal optical distortion and maintains consistent performance across a broad spectrum of wavelengths. The mirror's thickness varies from 2.81 mm at the edge to 3 mm at the center, providing robustness and stability.

The 87-693 mirror is coated with a protected gold coating, specifically designed to enhance its performance within the 700-2000nm wavelength range. This coating not only improves the mirror's reflectivity but also provides durability, ensuring the mirror maintains its optical properties even under harsh environmental conditions.

This mirror is currently in stock and available for immediate purchase, making it an ideal choice for those seeking high-quality, readily available optical components. For more information, including pricing and detailed specifications, please refer to the provided weblink.
