The CSMH-12.7-800 is a dielectric half-mirror cube beamsplitter, designed and manufactured by OptoSigma. This beamsplitter is a crucial component in various optical systems, particularly those that require the splitting or combining of light beams.
The beamsplitter is constructed with a 12.7 mm x 12.7 mm x 12.7 mm N-BK7 cube, a high-quality glass material known for its excellent optical properties. The N-BK7 cube is coated with a dielectric coating, which is ideal for broadband applications, ensuring high reflectivity and transmissivity across the specified wavelength range.
The CSMH-12.7-800 offers a 50:50 (R:T) split ratio, meaning it reflects and transmits incoming light beams equally. This makes it suitable for applications where balanced splitting of light is required. The beamsplitter is designed to operate within the wavelength range of 750-850nm, making it suitable for near-infrared (NIR) applications.
The beamsplitter's coating is a broadband AR coating on all surfaces, including the hypotenuse faces. This coating ensures minimal reflection and loss of light, enhancing the overall efficiency of the optical system.
