CM254-150-P01 Dia:1 in Concave Mirror; f=150.0 mm Protected Silver

The CM254-150-P01 is a concave mirror with a diameter of 1 inch (25.4 mm) and a focal length of 150.0 mm. This mirror is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The mirror is designed with a spherical shape, which is a common choice for many optical applications due to its simplicity and versatility.

The mirror's base shape is circular, and it has a thickness of 6.3 mm at the edge and 6 mm at the center. This slight variation in thickness is a common feature in optical components, designed to optimize performance and durability. The mirror's effective focal length (EFL) is 150 mm, which is a critical specification for any concave mirror. The EFL is the distance from the mirror at which parallel rays of light converge after reflection, and it is a key factor in determining the mirror's magnification and focusing power.

The CM254-150-P01 is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes it an ideal choice for a wide range of applications, including imaging, laser systems, and interferometry. The mirror is coated with a protected silver coating (tho p01protsilrefl12), which provides high reflectivity across a broad spectrum of wavelengths. This coating is also designed to be durable and resistant to tarnish, ensuring long-lasting performance.

The mirror's geometry and material specifications are optimized for a center wavelength of 588 nm. This wavelength falls within the visible light spectrum, making the mirror suitable for applications involving visible light. However, due to its broadband coating, the mirror can also be used with other wavelengths, making it a versatile choice for many optical systems.
