47-949 50 x 50 mm N-BK7 45 deg Reflective Blue Dichroic Filter; t=4 mm 400-800nm

The 47-949 is a 50 x 50 mm dichroic filter, designed with a 45-degree angle of incidence and manufactured by the renowned optical vendor, Edmund Optics. This filter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, produced by Schott, a leading glass manufacturer.

The filter's primary function is to reflect a specific wavelength of light while transmitting others. In this case, it is designed to reflect the 588nm wavelength, making it ideal for applications that require the separation or enhancement of this specific light frequency.

The 47-949 filter has a cut-on wavelength of 0nm and a cut-off wavelength of 510nm, indicating its ability to transmit wavelengths up to 510nm and reflect those beyond. This makes it suitable for use in a wide range of applications, particularly where blue light manipulation is required.

The filter has a thickness of 4mm, providing durability and resistance to optical deformation. It is coated on both the front and back with EDM 47-264, a proprietary coating developed by Edmund Optics, further enhancing its performance and longevity.

This filter is available in a thin lens shape, making it compatible with various optical systems. According to Edmund Optics' website, as of the time of this description, the filter is in stock, ensuring quick and reliable delivery for your optical needs.
