48-908 75 x 75 mm 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm
This 48-908 beamsplitter, sourced from Edmund Optics, is a rectangular plate beamsplitter with dimensions of 75 x 75 mm and a thickness of 3mm. It is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity.
The beamsplitter features a 70:30 (R:T) split, meaning it reflects 70% of the incoming light and transmits 30%. This specific model is designed for the visible spectrum, with a central wavelength of 588nm, and operates effectively within the 400-700nm range.
The coating on the front surface is EDM 48-394, which is specifically designed for this type of beamsplitter. The beamsplitter's shape is that of a thin lens, making it suitable for a wide range of optical applications.
Please note that the physical data provided, such as the reflection and transmission rates, are specific to the central wavelength and may vary across the operational spectrum. Always refer to the vendor's specifications for precise data.
