10BPF10-239 25.4 mm Dia. Argon-Gap UV Bandpass Filter 239nm
The 10BPF10-239 is a circular bandpass filter, designed and manufactured by MKS/Newport, a leading vendor in the optical industry. This filter is specifically engineered for use in ultraviolet (UV) applications, with a central wavelength of 239nm.
The filter has a diameter of 25.4mm and a thickness of 5.1mm, making it compatible with a wide range of optical systems. The base shape of the filter is circular, a common choice for its ease of integration and alignment in various setups.
The 10BPF10-239 features a unique argon-gap coating on both the front and back surfaces. This coating is designed to provide a high transmission rate for UV light at the specified central wavelength, while effectively blocking unwanted wavelengths. The cut-on wavelength is 233.5nm, and the cut-off wavelength is 244.5nm, ensuring a tight bandpass for optimal performance.
The physical data of the filter, including the cut-on and cut-off wavelengths, are precisely controlled during the manufacturing process to ensure consistent performance. The filter's geometry and physical data make it an ideal choice for UV applications that require a high degree of wavelength selectivity.
