This is a PMH-30C03-10-6/18 30 mm Dia. N-BK7 Ultra Broadband Dielectric Half-Mirror Plate Beamsplitter, sourced from OptoSigma. The beamsplitter is a circular plate with a diameter of 30 mm and a thickness of 3 mm. It is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The beamsplitter is designed for use in the ultra-broadband spectrum, specifically between 600 and 1800 nm. This makes it a versatile component for a wide range of optical systems. The beamsplitter's coating is Opt PMH-600-1800, which is a dielectric coating that provides high reflectivity and transmissivity within the specified wavelength range.
The beamsplitter's physical data indicates that it has a reflection of 0.5 and a transmission of 0.5. This means that approximately half of the incident light will be reflected, while the other half will be transmitted. This 50/50 split is a common characteristic of beamsplitters and is useful in many optical applications.
