This 87-666 optical mirror, sourced from Edmund Optics, is a 25mm diameter plano-convex spherical mirror with a focal length (EFL) of 12.5mm. The mirror is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The mirror's geometry includes a thickness of 1.65mm at the edge, gradually increasing to 5mm at the center. This curvature, combined with the mirror's spherical shape, allows for effective light reflection and focusing. The coating on the front surface is an enhanced aluminum coating, designed to enhance reflectivity within the 450-650nm wavelength range.
The mirror's web links are valid and indicate that it is currently in stock, making it readily available for immediate use. This mirror is a versatile and reliable choice for various optical systems, offering high-quality performance and durability.
