This is a 43-582 76.2 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. The mirror, which is uncoated, boasts an effective focal length (EFL) of 203.2mm and a diameter of 76.2mm.
The mirror's geometry is defined by a thickness edge of 12.7mm and a radius of curvature (R1) of -406.4mm, indicating its concave shape. The mirror is made of borofloat33, a type of glass known for its high resistance to thermal shock and excellent transmission properties in the ultraviolet, visible, and near-infrared spectral ranges.
The mirror's spherical shape ensures a constant curvature across the entire surface, making it suitable for a wide range of optical applications. The uncoated surface allows for customized coatings based on specific application requirements.
Please note that the mirror's specifications are valid for a wavelength of 588nm. The mirror is currently in stock and available for immediate purchase through the provided weblink.
