400FS20-25 25mm Dia. 400nm Bandpass Filter, HBW 20nm

The 400FS20-25 is a high-quality bandpass filter developed by Andover Corporation, a leading vendor in the optical industry. This filter, with a catalog number of 400FS20-25, is specifically designed for use in the 400nm wavelength range, making it ideal for applications that require precise filtering in this spectrum.

The filter has a base shape of a circle, with a diameter of 25mm, providing a large surface area for efficient light transmission. It has a thickness of 5.9mm, ensuring durability and stability during operation. The 400FS20-25 filter features a cut-on wavelength of 390nm and a cut-off wavelength of 410nm, with a central wavelength (CWL) of 400nm. This means it allows light within the 400nm range to pass through while blocking out light from other wavelengths.

The 400FS20-25 filter is made from UVFS MAL-1965 material, a high-performance optical material known for its excellent transmission characteristics and durability. The filter is coated on both the front and back with And 400FS20, a specialized coating that enhances its performance and longevity.

The filter's geometry and physical data make it suitable for a wide range of applications, including spectroscopy, fluorescence microscopy, and other scientific research where precise wavelength filtering is required. The filter is currently in stock and available for immediate purchase through Andover Corporation's official website.
