49-472 35 x 35 mm N-BK7 45 deg Reflective Blue Dichroic Filter; t=3 mm 400-800nm

This is a 35 x 35 mm N-BK7 45 degree Reflective Blue Dichroic Filter, offered by the renowned optical components vendor, Edmund Optics. The filter is catalogued under the number 49-472 and is currently in stock, as indicated by its weblink status.

The filter is a Dichroic type, designed to selectively reflect or transmit light depending on its wavelength. In this case, the filter is designed to reflect blue light, making it ideal for applications where blue light needs to be isolated or enhanced.

The filter is made from N-BK7, a high-quality borosilicate glass manufactured by Schott. This material is known for its excellent optical properties, making it a popular choice for a wide range of optical applications.

The filter has a thickness of 3 mm and is designed to operate within the wavelength range of 400-800 nm. The physical data of the filter indicates a cut-on wavelength of 0 nm and a cut-off wavelength of 510 nm. This means that the filter will begin to transmit light at 0 nm and will stop transmitting at 510 nm, effectively reflecting all wavelengths above this point.

The filter features the same coating on both the front and back surfaces, specifically EDM 47-264. This coating is designed to enhance the filter's performance, ensuring optimal reflection and transmission of light.

The filter is shaped as a Thin Lens, which is a type of lens with a very small focal length compared to its diameter. This shape allows the filter to be used in a variety of optical systems, making it a versatile component in any optical setup.
