FL05514.5-1 Dia:0.5 in Laser Line Filter; CWL=514.5 +-0.2nm; FWHM=1 +-0.2nm

The FL05514.5-1 is a circular bandpass filter with a diameter of 0.5 inches, manufactured by Thorlabs. This filter is designed to transmit light in a narrow range of wavelengths around 514.5 nm, making it ideal for use with laser systems operating at this wavelength.

The filter is made from soda lime ru clear material and has a thickness of 3.5 mm. It features a thin lens shape, which can help to focus or collimate light beams. The front and back surfaces of the filter are coated with a specialized coating, denoted as 'tho fl05514.5-1', which is designed to enhance its performance in terms of transmission and blocking unwanted wavelengths.

The physical data of the filter includes a cut-on wavelength of 514 nm and a cut-off wavelength of 515 nm. The central wavelength (CWL) is specified as 514.5 nm, with a full width at half maximum (FWHM) of 1 nm, indicating a very narrow transmission band. This makes the filter highly suitable for applications requiring precise wavelength selection.
