48-395 12.5 mm Dia. 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

This beamsplitter, sourced from Edmund Optics, is a circular plate with a diameter of 12.5 mm and a thickness of 3 mm. It is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and high homogeneity.

The beamsplitter features a 70:30 (R:T) coating, which means that it reflects 70% of the incident light and transmits 30%. This coating is specifically designed for the near-infrared (NIR) region, with a wavelength of 1064 nm, making it suitable for a wide range of applications in this spectral range.

The coating on the front surface of the beamsplitter is EDM 48-395. This coating is known for its high damage threshold and excellent environmental stability, making it suitable for use in harsh environments.

The beamsplitter is designed as a thin lens, which minimizes unwanted optical effects such as aberrations and distortions. This makes it an ideal choice for applications that require high optical precision and accuracy.
