68-381 12.5 mm Dia. 40:60 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-381 is a high-quality beam splitter from Edmund Optics, designed with a 12.5 mm diameter and a thickness of 3mm. This beamsplitter is made from N-BK7 Schott, a popular optical glass due to its excellent homogeneity, low optical dispersion, and high transmittance in the visible spectrum.

The beamsplitter features a 40:60 (R:T) ratio, meaning it reflects 40% of the incident light and transmits 60%. This ratio is particularly useful in applications where balanced light distribution is required. The coating on the front surface is EDM 68-381, specifically designed to enhance the performance of the beamsplitter in the visible spectrum, between 400-700nm.

The beamsplitter's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for immediate purchase from the Edmund Optics website. This beamsplitter is a reliable and versatile component, ideal for a wide range of applications in fields such as biomedical research, machine vision, and optical metrology.
