86-644 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 600nm

The 86-644 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 600nm, making it ideal for applications that require precise wavelength selection.

The filter boasts a hard coating on both the front and back surfaces, denoted as 'edm 86-644'. This coating enhances the filter's durability, making it resistant to scratches and other forms of wear and tear. The geometry of the filter includes a thickness of 3.5 mm, which contributes to its overall robustness and stability.

The 86-644 features a Cut-on wavelength of 587.5nm and a Cut-off wavelength of 612.5nm. These specifications ensure that the filter effectively transmits light within the desired wavelength range while blocking unwanted wavelengths. The Cut-on and Cut-off wavelengths are crucial in determining the filter's performance and are carefully controlled during the manufacturing process.

The filter's physical data includes a Center Wavelength (CWL) of 600nm. The CWL is the wavelength at which the filter's transmission is maximum. This value is a key parameter in selecting the right filter for your specific application.

The filter's shape is defined as a Thin Lens, which is a type of optical component with a curved surface that bends light as it passes through. This shape is often used in optical systems to focus or collimate light.
