193FS15-25 25mm Dia. 193nm Bandpass Filter, FWHM 15nm

The 193FS15-25 is a high-quality bandpass filter developed by Andover Corporation, a leading vendor in the optical industry. This filter, with a catalog number 193FS15-25, is specifically designed for applications that require narrow-band light transmission around the 193nm wavelength.

The filter has a circular shape with a diameter of 25mm, making it compatible with a wide range of optical systems. It features a thickness of 3.5mm, providing robustness and stability during integration. The base material of this filter is UVFS Mal-1965, ensuring reliable performance in ultraviolet applications.

The 193FS15-25 filter is designed to transmit light within a specific wavelength range, with a central wavelength (CWL) of 193nm. The cut-on wavelength is 185.5nm, and the cut-off wavelength is 200.5nm, indicating a full width at half maximum (FWHM) of 15nm. This narrow bandwidth ensures high spectral purity and reduces unwanted noise in the output signal.

The filter is coated on both sides with And 193FS15, 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 shape is that of a thin lens, further optimizing its performance in optical systems.

The 193FS15-25 filter is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.andovercorp.com/products/bandpass-filters/standard/193-299nm/.
