214FIB25 25 mm Dia. Interference Bandpass Filter 214-320nm
The 214FIB25 is a circular Bandpass Filter with a 25 mm diameter and a thickness of 6.1 mm, sourced from Knight Optical. This filter is designed to transmit light within a specific wavelength range while blocking other wavelengths, making it ideal for applications that require wavelength selectivity.
The 214FIB25 is centered at 214 nm, with a cut-on wavelength of 209 nm and a cut-off wavelength of 219 nm. This narrow bandpass characteristic is achieved through the use of advanced interference filter technology, which ensures high transmission and excellent out-of-band rejection.
The filter is made from UVFS Mal- 1965, a material specifically chosen for its optical properties in the ultraviolet region. The front and back surfaces of the filter are coated with KNI 214FIB, a proprietary coating developed by Knight Optical to enhance the filter's performance and durability.
The 214FIB25 is shaped as a thin lens, which can be beneficial in certain optical systems where thin, lightweight elements are preferred. This filter is currently in stock and available for immediate purchase through the Knight Optical website.
