214FIB12 12.5 mm Dia. Interference Bandpass Filter 214-320nm
The 214FIB12 is a high-quality bandpass filter, designed and manufactured by Knight Optical. This particular model is a circular filter, with a diameter of 12.5 mm and a thickness of 6.1 mm, making it suitable for a wide range of optical applications.
The filter is designed to operate at a central wavelength (CWL) of 214 nm, with a cut-on wavelength of 209 nm and a cut-off wavelength of 219 nm. This specificity in wavelength makes it an ideal choice for applications that require precise filtering within the UV spectrum.
The 214FIB12 features a unique coating on both the front and back surfaces, denoted as 'kni 214fib'. This coating is specifically designed to enhance the filter's performance and durability, ensuring reliable and consistent operation.
The filter's geometry is that of a thin lens, which can be beneficial in applications where minimal thickness and weight are desirable. The filter is currently in stock and available for immediate purchase through the vendor's website, with the catalog number 214FIB12.
