68-551 25 x 25mm 30:70 (R:T) N-BK7 Standard Cube Beamsplitter; t=25mm 400-700nm

The 68-551 is a standard cube beamsplitter, measuring 25 x 25mm with a thickness of 25mm, sourced from the renowned optical components vendor, Edmund Optics. This beamsplitter is designed for use within the wavelength range of 400-700nm, making it suitable for a wide array of applications within the visible light spectrum.

The beamsplitter boasts a reflection ratio of 30:70 (R:T), meaning that 30% of the incident light is reflected while the remaining 70% is transmitted. This specific ratio is often utilized in various optical setups, offering a balance between reflection and transmission capabilities.

The beamsplitter is constructed using N-BK7 glass from Schott, a material well-known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior transmittance in the visible spectrum. The use of N-BK7 ensures high-quality performance and reliable results in your optical experiments and applications.

The coating applied to the beamsplitter is Edmund Optics' MgF2 standard curve on all surfaces, except for the hypotenuse faces. The hypotenuse faces are coated with Edmund Optics' vis R30 t70 coating on the first hypotenuse face and Edmund Optics' MgF2 standard curve on the second hypotenuse face. This specific coating configuration enhances the beamsplitter's performance and durability, making it an ideal choice for various optical systems.

The 68-551 beamsplitter is available in a cube shape, which is advantageous in terms of compactness and ease of integration into various optical setups. The beamsplitter's dimensions and shape make it a versatile component for a wide range of applications, from beam combining and splitting to interferometry and more.
