FSR-BG18 25.4 mm Dia. Colored Glass Absorptive Bandpass Filter 493nm

The FSR-BG18 is a high-quality Bandpass Filter, designed and manufactured by MKS/Newport. This filter is specifically engineered to allow transmission of light within a certain range of wavelengths, while blocking other wavelengths, making it an ideal component for various optical applications.

The filter has a circular shape with a diameter of 25.4 mm, ensuring a wide area of light transmission. It has a thickness of 3 mm, providing durability and stability. The FSR-BG18 is made of UVFS Mal-1965 material, a type of colored glass that is known for its excellent optical properties.

The FSR-BG18 is designed to transmit light at a central wavelength (CWL) of 493 nm. It has a cut-on wavelength of 413 nm and a cut-off wavelength of 573 nm. This means that it begins to transmit light at 413 nm and stops transmitting at 573 nm, effectively filtering out any wavelengths outside this range.

The filter is coated with a New FSR-BG18 coating on both the front and back surfaces. This coating enhances the filter's performance and durability. The filter's shape is that of a thin lens, further optimizing its light transmission capabilities.

The FSR-BG18 is currently in stock and available for purchase on the MKS/Newport website. It is a reliable and efficient optical component, perfect for applications that require precise wavelength selection.
