67-740 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 250nm

The 67-740 is a 12.5 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for applications that require precise wavelength selection within the ultraviolet spectrum.

The filter's primary function is to transmit light within a specific range, while blocking unwanted wavelengths. The 67-740 is designed to transmit light at a central wavelength (CWL) of 250nm, with a full width at half maximum (FWHM) of 10nm. This means it allows light transmission around the 250nm wavelength while blocking light on either side of this range.

The filter's physical dimensions include a diameter of 12.5mm and a thickness of 3.5mm. It is mounted, providing a convenient and secure method of integration into optical systems. The mounting process also ensures the filter's flatness and parallelism, which are critical for maintaining optical performance.

The 67-740 features a traditional coating on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating is specifically designed for Edmund Optics and is identified as 'edm 67-740'.

This filter is available in a thin lens shape, which is beneficial for applications where space is limited or weight is a critical factor. The filter's geometry and shape make it suitable for a wide range of applications, including spectroscopy, laser systems, and bio-imaging.
