66-248 35 x 35 mm N-BK7 45 deg Reflective Cyan Dichroic Filter; t=3 mm 400-725nm

The 66-248 is a 35 x 35 mm dichroic filter with a 45-degree angle of incidence, manufactured by Edmund Optics. This filter is made from N-BK7 Schott glass, a popular choice for its excellent optical properties and high damage threshold. The filter's primary function is to reflect cyan light, making it ideal for applications that require the separation or enhancement of this specific wavelength.

The filter's coating, EDM 66-242, is applied to both the front and back surfaces. This coating is designed to enhance the filter's performance, ensuring efficient and reliable operation. The filter has a thickness of 3 mm, providing sufficient structural integrity for most applications.

The 66-248 filter is designed to operate within the wavelength range of 400-725 nm. This broad spectrum makes it versatile for a wide range of applications, including fluorescence microscopy, spectroscopy, and laser systems. The filter's cut-on wavelength is 0 nm, and the cut-off wavelength is 590 nm, indicating that it allows shorter wavelengths to pass through while blocking longer wavelengths.

This filter is available in a thin lens shape, which is advantageous for applications that require compact, lightweight optical components. The filter's rectangular geometry, with a width of 35 mm and a height of 35 mm, provides flexibility in optical design, allowing it to be easily integrated into various systems.
