39-343 25 mm Dia. Hard Coated OD 4.0 5nm Bandpass Filter; t=3.5 mm 343nm
The 39-343 is a Bandpass Filter with a 25 mm diameter and a thickness of 3.5 mm, designed for use with a center wavelength of 343 nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is part of their extensive catalog of optical elements.
The filter is made from UVFS Mal-1965 material, a common choice for applications that require high transmission and excellent blocking characteristics. The front and back of the filter are coated with EDM 39-328, a coating that enhances the filter's performance and durability.
The 39-343 filter is designed with a cut-on wavelength of 340.5 nm and a cut-off wavelength of 345.5 nm, providing a narrow bandwidth of 5 nm. This makes it ideal for applications that require precise wavelength selection, such as fluorescence microscopy, spectroscopy, and laser applications.
The filter's thin lens shape allows for easy integration into optical systems, while its hard coating provides additional protection against scratches and other forms of damage. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
