67-802 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9 mm 220nm

The 67-802 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in applications where precise wavelength selection and narrow bandwidth are critical. The filter features a center wavelength (CWL) of 220nm, with a full width at half maximum (FWHM) of 10nm, providing a high degree of wavelength specificity.

The filter is constructed with a base shape of a circle, and has a thickness of 5.9mm. The material used in the construction of this filter is UVFS Mal-1965, a material well-suited for applications in the ultraviolet spectrum. The filter is coated on both the front and back surfaces with EDM 67-735, a proprietary coating developed by Edmund Optics for enhanced performance and durability.

The 67-802 filter is designed with a cut-on wavelength of 215nm and a cut-off wavelength of 225nm. This means that the filter begins to transmit light at 215nm and stops transmitting at 225nm, providing a very narrow band of wavelengths for transmission. This makes the filter ideal for use in applications such as fluorescence microscopy, spectroscopy, and other applications where precise wavelength control is necessary.

The filter is mounted for ease of use, and is available for purchase directly from the Edmund Optics website. The current status of the filter is in stock, ensuring quick and efficient delivery.
