67-890 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=6.9 mm 330nm
The 67-890 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter features a circular shape with a 50 mm diameter and a thickness of 6.9 mm, making it suitable for various optical applications. The filter is made of UVFS Mal-1965 material, ensuring durability and reliability.
The 67-890 filter is designed to transmit light in the 330 nm range, with a center wavelength (CWL) of 330 nm. It has a full width at half maximum (FWHM) of 10 nm, which refers to the bandwidth of the filter at half its maximum transmission. The cut-on wavelength is 325 nm, and the cut-off wavelength is 335 nm, indicating the range of wavelengths that the filter allows to pass.
The filter is coated with EDM 67-756 on both the front and back surfaces, providing additional protection and enhancing its performance. The shape of the filter is thin lens, which is beneficial for applications that require minimal thickness and weight.
