900FSX20-25 25mm Dia. 900nm High-Transmitting Bandpass Filter, HBW 20nm
The 900FSX20-25 is a high-performance bandpass filter developed by Andover Corporation, a leading vendor in the optical industry. This filter, with a catalog number 900FSX20-25, is specifically designed for applications that require a narrow bandwidth transmission in the 900nm range.
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 high-quality material known for its excellent optical properties.
The 900FSX20-25 features a high transmission bandwidth (HBW) of 20nm, centered at 900nm. The cut-on wavelength is 890nm, and the cut-off wavelength is 910nm, ensuring a tight and precise passband. This makes it ideal for applications that require narrowband filtering, such as fluorescence microscopy, spectroscopy, and laser systems.
The filter is coated with And 900fsx20 on both the front and back surfaces, providing enhanced durability and resistance to environmental factors. The coating also helps to reduce reflections and increase transmission, further enhancing the performance of the filter.
The filter is available in a thin lens shape, which is beneficial for applications where space is a constraint. The filter is currently in stock and available for immediate shipping. For more information, please visit the Andover Corporation website.
