67-814 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 289nm
The 67-814 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in applications that require precise wavelength selection and narrow bandwidths. The filter features a center wavelength of 289nm, with a full-width half-maximum (FWHM) of 10nm, providing a high degree of wavelength specificity.
The filter is constructed with a base shape of a circle, and it has a thickness of 3.5mm. This robust construction ensures durability and stability, making it suitable for a wide range of optical applications. The filter is coated with EDM 67-747 on both the front and back surfaces, enhancing its performance and longevity.
The 67-814 filter has a cut-on wavelength of 284nm and a cut-off wavelength of 294nm. This wavelength range is ideal for applications that require the selective transmission of ultraviolet light. The filter is designed to be mounted, providing ease of use and integration into optical systems.
The physical data of the filter, including its cut-on, cut-off, and center wavelength, are precisely controlled during the manufacturing process. This ensures consistent performance and reliability, making the 67-814 an excellent choice for applications that require precise wavelength control.
