This is a 12.5 x 12.5mm 70:30 (R:T) N-BK7 Standard Cube Beamsplitter, sourced from Edmund Optics. The beamsplitter is designed for use in the 400-700nm wavelength range, making it suitable for a wide range of applications.
The beamsplitter is a cube-shaped optical element, with each side measuring 12.5mm. This compact design makes it easy to integrate into various optical systems. The beamsplitter features a 70:30 reflection to transmission ratio, meaning that approximately 70% of the incident light is reflected, while the remaining 30% is transmitted.
The beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared regions of the spectrum.
The beamsplitter's coating is another key feature. Both the front and back surfaces, as well as the left and right surfaces, are coated with an edm mgf2 std curve coating. This coating enhances the beamsplitter's performance in the 400-700nm wavelength range. The hypotenuse 1 surface is coated with an edm vis r70 t30 coating, while the hypotenuse 2 surface is coated with an edm mgf2 std curve coating.
