46-664 12.5 mm Dia. 25:75 (R:T) Float Glass Standard Plate Beamsplitter; t=1mm 400-700nm

This 12.5 mm diameter beamsplitter, model 46-664, is a high-quality optical component sourced from Edmund Optics. It is designed to split incoming light beams into reflected and transmitted components, with a specified ratio of 25:75 (R:T) for the reflected and transmitted light respectively. The beamsplitter is made of float glass, a type of soda lime glass known for its clarity and durability.

The beamsplitter has a thickness of 1mm, providing a good balance between robustness and light manipulation. It is designed to operate within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications, including but not limited to, biomedical imaging, machine vision, and optical metrology.

The front surface of the beamsplitter is coated with a proprietary coating, referred to as 'edm 46-664', which enhances its performance in terms of reflectivity and transmission. The back surface, on the other hand, is coated with a standard magnesium fluoride coating, denoted as 'edm mgf2 std curve'. This coating helps to reduce unwanted reflections and improves the overall efficiency of the beamsplitter.

The beamsplitter is shaped as a thin lens, which not only provides a larger surface area for light interaction but also allows for easier integration into optical systems. According to the provided data, the beamsplitter has a reflection coefficient of 0.25 and a transmission coefficient of 0.75, ensuring efficient light splitting and minimal loss of signal.

In conclusion, the 46-664 12.5 mm Dia. 25:75 (R:T) Float Glass Standard Plate Beamsplitter is a versatile and reliable optical component, ideal for various applications requiring light beam splitting. Its robust construction, wide wavelength range, and efficient light management make it a valuable addition to any optical system.
