10BPF10-228 25.4 mm Dia. Argon-Gap UV Bandpass Filter 228nm

The 10BPF10-228 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 228nm. The filter is 25.4mm in diameter, making it suitable for a wide range of optical systems.

The filter is constructed with an Argon-Gap design, which is a unique approach that uses a gap filled with argon gas between two coatings. This design provides superior performance in terms of blocking unwanted wavelengths and transmitting the desired band of light. The cut-on wavelength is 222.5nm, and the cut-off wavelength is 233.5nm, further enhancing its bandpass characteristics.

The 10BPF10-228 filter has a thickness of 5.1mm, providing robustness and durability. The front and back surfaces of the filter are coated with the "new 10bpf10-228" coating, which enhances its optical performance and overall lifespan. The filter's shape is that of a thin lens, ensuring easy integration into various optical setups.

According to the vendor's website, the filter is currently in stock, indicating its availability for immediate purchase and use. The filter's catalog number is 10BPF10-228, and it can be found on Newport's official website for further details and specifications.
