700FSX20-25 25mm Dia. 700nm High-Transmitting Bandpass Filter, HBW 20nm
The 700FSX20-25 is a high-performance bandpass filter developed by Andover Corporation, a leading vendor in the optical industry. This filter, with a catalog number 700FSX20-25, is specifically designed for applications that require a high transmission bandwidth and narrow passband.
The filter is circular in shape with a diameter of 25mm and a thickness of 5.9mm, making it compatible with a wide range of optical systems. It is made from UVFS MAL-1965, a material known for its excellent optical properties.
The 700FSX20-25 has a central wavelength (CWL) of 700nm, and it is designed to pass wavelengths within a narrow band centered around this CWL. The cut-on wavelength is 690nm, and the cut-off wavelength is 710nm, indicating a high-transmitting bandwidth of 20nm (HBW 20nm). This makes it ideal for applications that require a high level of wavelength selectivity.
The filter is coated on both sides with Andover's proprietary coatings, denoted as 'and 700fsx20' for both the front and back surfaces. These coatings enhance the filter's performance by reducing reflections and increasing transmission.
The 700FSX20-25 is available for purchase directly from Andover Corporation's website, and it is currently in stock. For more information, users are encouraged to visit the provided weblink.
