87-681 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=150mm Protected Silver 450-10000nm

This is a 25 mm diameter Plano-Convex Spherical Mirror, model 87-681, sourced from the renowned optical components vendor, Edmund Optics. The mirror boasts a 150mm effective focal length (EFL), 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 is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The mirror's base shape is circular, with a thickness of 2.74mm at the edge and 3mm at the center, providing robustness and stability.

The mirror's coating is a protected silver, which offers high reflectivity across a broad spectrum, ranging from 450nm to 10000nm. This wide spectral range makes the mirror versatile, suitable for various applications, including infrared (IR) and ultraviolet (UV) systems.

The mirror's geometry is spherical, with a radius of curvature (R1) of 300mm. This curvature, combined with the mirror's EFL, allows for precise focusing and reflection of light, enhancing the performance of optical systems.

The mirror is currently in stock and available for immediate purchase. For more detailed information, including pricing and delivery times, please refer to the provided web link: https://www.edmundoptics.com/p/25mm-dia-x150mm-fl-protected-silver-convex-mirror/30007/
