091-0130R-75 12.7 mm Dia. N-BK7 Protected Gold Spherical Plano-Concave Mirror; t=6mm 900nm
This 091-0130R-75 mirror is a curved mirror with a concave base shape and a spherical geometry, sourced from EKSMA Optics. The mirror has a diameter of 12.7 mm and a thickness edge of 6 mm, making it a compact and robust option for various optical applications.
The mirror's material is N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence and high transmittance in the visible and near-infrared spectral ranges.
The mirror features a protected gold coating (eks 0030protgold900) on the front surface, designed to enhance reflectivity at the specified wavelength of 900 nm. The coating is protected, ensuring durability and longevity, even under harsh environmental conditions.
The mirror's effective focal length (EFL) is -37.5, indicating a concave geometry that focuses light to a point on the optical axis. This property makes the mirror suitable for applications requiring light concentration or collimation, such as beam shaping, imaging, and interferometry.
