67-747 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 289nm

The 67-747 is a mounted traditional coated bandpass interference filter, available from Edmund Optics. This filter is characterized by its circular shape, with a diameter of 12.5 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical applications.

The filter is designed to operate at a central wavelength (CWL) of 289nm, with a full width at half maximum (FWHM) of 10nm. This specificity makes it ideal for applications that require precise wavelength selection and narrow bandwidth, such as fluorescence microscopy or spectroscopy.

The 67-747 filter features a cut-on wavelength of 284nm and a cut-off wavelength of 294nm. This wavelength range is achieved through the use of advanced coating technologies, which are applied to both the front and back surfaces of the filter. The coating is identified as 'edm 67-747' for both surfaces, suggesting a consistent and uniform application.

The filter is mounted, which adds to its convenience and ease of use. The mounting ensures the filter is securely held in place, reducing the risk of damage during handling or operation. The mount also facilitates integration with other optical components, making it a versatile choice for various setups.

In terms of availability, the filter's weblink status is 'Valid - in stock', indicating that it is readily available for purchase and use. This, coupled with its specifications, makes the 67-747 an attractive option for those seeking a reliable and high-performance bandpass interference filter.
