265FS10-50 50mm Dia. 265nm Bandpass Filter, HBW 10nm

The 265FS10-50 is a Bandpass Filter with a diameter of 50mm, specifically designed to operate at a central wavelength of 265nm. This filter, offered by Andover Corporation, is a crucial component in various optical systems that require narrowband transmission within the specified wavelength range.

The filter's physical data includes a cut-on wavelength of 260nm and a cut-off wavelength of 270nm, ensuring a high-bandwidth (HBW) transmission of 10nm. This narrow bandwidth is essential for applications that demand high spectral purity and rejection of out-of-band wavelengths.

The 265FS10-50 filter is made of UVFS Mal-1965 material, a common choice for ultraviolet applications due to its excellent transmission characteristics and durability. The filter has a thickness of 3.5mm, providing sufficient mechanical strength for handling and integration into optical systems.

The front and back surfaces of the filter are coated with And 265FS10, a proprietary coating developed by Andover Corporation. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The filter's thin lens shape allows for easy integration into various optical systems, while its circular geometry provides uniform illumination and transmission across the aperture. The filter is currently in stock and available for immediate purchase through Andover Corporation's official website.
