CM750-500-G01 Dia:75 mm Concave Mirror; f=500.0 mm Protected Aluminum
The CM750-500-G01 is a concave mirror offered by Thorlabs with a diameter of 75 mm and a focal length of 500.0 mm. This mirror is designed to focus or collimate light, making it suitable for various applications in optical systems.
The mirror's base shape is circular, and it features a spherical geometry. The edge thickness is 12.7 mm, while the center thickness is 12 mm, providing structural rigidity. The mirror's effective focal length (EFL) is 500 mm, determined by the radius of curvature (R1), which is -1000 mm.
The mirror is made of n-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high damage threshold. The coating on the front surface is tho g01protalrefl12, a protected aluminum coating that enhances reflectivity while providing durability.
This mirror is designed to operate at a wavelength of 588 nm. The 'protected' in the coating description indicates that there is a layer of SiO2 or similar material over the aluminum coating, providing additional protection against oxidation and environmental damage.
