47-267 25 mm Dia. N-BK7 45 deg Reflective Blue Dichroic Filter; t=4 mm 400-800nm

The 47-267 is a 25 mm diameter Dichroic Filter, designed with a 45-degree angle of incidence and a reflective blue coating. This filter is sourced from the reputable optical vendor, Edmund Optics. It is specifically designed for use within the wavelength range of 400-800nm, making it suitable for a wide range of optical applications.

The filter is constructed from N-BK7 Schott glass, a popular choice due to its excellent optical properties and high Abbe number. The N-BK7 Schott glass has a diameter of 25mm and a thickness of 4mm, providing a robust and stable platform for the dichroic coating.

The dichroic coating on both the front and back surfaces of the filter is EDm 47-264. This coating is designed to reflect specific wavelengths of light while transmitting others, making it ideal for applications such as beam combining, wavelength separation, or laser pulse compression.

The filter's geometry is defined by its thin lens shape, and it has a cut-on wavelength of 0nm and a cut-off wavelength of 510nm. This means that it will begin transmitting light at 0nm and stop transmitting at 510nm, reflecting any light beyond this point.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more detailed information or to make a purchase, users can follow the provided weblink.
