FF02-482/18-25 25 mm Dia. 482/18nm BrightLine Single-Band Bandpass Filter by Semrock

The FF02-482/18-25 is a high-quality Bandpass Filter, designed and manufactured by Semrock, a leading vendor in the optical industry. This filter, with a circular shape and a diameter of 25 mm, is specifically designed for use in systems where a narrow bandwidth transmission is required.

The filter's primary function is to allow light to pass within a specific range of wavelengths, while blocking light outside this range. The FF02-482/18-25 is designed to pass wavelengths around 482 nm, with a full width at half maximum (FWHM) of 18 nm. This is achieved through the use of Semrock's proprietary BrightLine® coating technology, which ensures high transmission and excellent out-of-band blocking.

The filter's physical data includes a cut-on wavelength of 473 nm and a cut-off wavelength of 491 nm. This means that it begins to transmit light at 473 nm and stops transmitting at 491 nm, making it ideal for applications where a narrow, specific wavelength range is needed.

The FF02-482/18-25 has a thickness of 2 mm and features Semrock's FF02-48218 coating on both the front and back surfaces. This coating is designed to provide high transmission and excellent out-of-band blocking, ensuring optimal performance in your optical system.

The filter is available for purchase directly from the Semrock website, where it is listed as in stock. For more information, including detailed specifications and performance data, please refer to the product page on the Semrock website.
