The FF02-485/20-25 is a single-band Bandpass Filter, designed to transmit light within a specific range of wavelengths while blocking light outside this range. The central wavelength (CWL) of this filter is 485 nm, with a cut-on wavelength of 475 nm and a cut-off wavelength of 495 nm. This precise wavelength range is achieved through the application of a specialized coating on both the front and back surfaces of the filter, identified as 'sem ff02-48520'.

The filter's physical data further illustrates its performance. The cut-on and cut-off wavelengths define the range within which the filter transmits light with high efficiency. The cut-on wavelength of 475 nm indicates that the filter begins to transmit light at this wavelength, while the cut-off wavelength of 495 nm indicates that the filter stops transmitting light at this point. The central wavelength of 485 nm falls within this range, representing the wavelength at which the filter's transmission is at its maximum.

In terms of shape, the FF02-485/20-25 features a Thin Lens design, which is often utilized in optical systems to minimize optical aberrations and improve overall system performance. This filter is an excellent choice for applications that require precise wavelength selection and high transmission efficiency.
