72-502 254 x 356 mm 40:60 (R:T) Float Glass Standard Plate Beamsplitter; t=3mm 400-700nm

This 72-502 Beam Splitter, sourced from Edmund Optics, is a high-quality optical component designed for applications that require precise beam splitting. The beamsplitter features a rectangular base shape with dimensions of 254 mm in width and 356 mm in height, making it suitable for a wide range of optical systems.

The beamsplitter is constructed from soda lime glass, which is known for its excellent optical properties and durability. The glass has a thickness of 3mm, providing robustness and stability. The beamsplitter is designed to operate within the wavelength range of 400-700nm, making it suitable for a wide range of applications, including but not limited to, biomedical imaging, machine vision, and laser systems.

The beamsplitter features a 40:60 (R:T) split ratio, meaning that 40% of the incident light is reflected while 60% is transmitted. This split ratio is achieved through the use of specific coatings on the front and back surfaces of the beamsplitter. The front surface is coated with EDM 46-665, while the back surface is coated with EDM MGF2 STD CURVE. These coatings are designed to provide high-performance beam splitting while maintaining excellent transmission and reflection characteristics.

The beamsplitter is shaped as a thin lens, which helps to minimize optical aberrations and distortions. The physical data of the beamsplitter indicates a reflection of 0.4 and a transmission of 0.6, which aligns with the specified 40:60 (R:T) split ratio.
