68-423 25 x 25 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-423 is a high-quality beam splitter, designed and manufactured by Edmund Optics, a leading global manufacturer and supplier of optical components. This particular model boasts a rectangular shape, with dimensions of 25 x 25 mm, and a thickness of 3mm, making it a versatile choice for a wide range of optical applications.

The beam splitter is crafted from N-BK7, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This material is identified in the item data as "n-bk7 schott," indicating its Schott glass origin, a trusted name in the optical industry.

The 68-423 features a broad wavelength range of 400-700nm, encompassing the visible light spectrum. This makes it suitable for applications that require the manipulation of visible light, such as biomedical imaging, machine vision, and optical metrology.

The beamsplitter's coating, specified as "edm 68-417," is applied to the front surface. This coating is designed to achieve a specific reflection-to-transmission ratio, in this case, 80:20 (R:T). This means that 80% of the incident light is reflected, while 20% is transmitted, offering precise control over light paths in optical systems.
