49-003 12.5 x 12.5mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=12.5mm VIS 430-670nm

The 49-003 is a non-polarizing cube beamsplitter, designed and manufactured by Edmund Optics. This beamsplitter is part of their extensive catalog, which includes a wide variety of optical elements from different vendors worldwide. The 49-003 is specifically designed for use in the visible spectrum, with a wavelength range of 430-670nm.

The beamsplitter has a cube side dimension of 12.5mm, and its geometry is defined by a width of 12.5mm and a thickness of 12.5mm. The beamsplitter's physical data indicates a 50:50 reflection to transmission ratio (R:T) for the incident light. This means that approximately half of the incident light will be reflected, while the other half will be transmitted.

The 49-003 is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The beamsplitter's coating is ideal broadband AR on all surfaces, ensuring high transmission and low reflection across the specified wavelength range.

The beamsplitter's shape is that of a cube, which is a common design for beamsplitters due to its simplicity and robustness. The cube design also allows for easy integration into optical systems, as it provides a straightforward way to align and mount the beamsplitter.
