10BPF25-400 25.4 mm Dia. Standard Bandpass Filter 400nm

The 10BPF25-400 is a standard bandpass filter with a diameter of 25.4 mm, specifically designed for a central wavelength of 400nm. This filter is sourced from the reputable vendor MKS/Newport, and it is currently in stock, as indicated by its weblink status.

The filter is of the bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. This particular model has a cut-on wavelength of 387.5nm and a cut-off wavelength of 412.5nm, making it ideal for applications that require narrow-band light in the ultraviolet range.

The 10BPF25-400 is made from UVFS Mal-1965, a material known for its optical properties in the UV range. It has a thickness of 6.35mm and a circular base shape, which is common for filters due to its ease of integration into various optical systems.

The filter's coating is consistent on both the front and back surfaces, with a new 10bpf25-400 coating. This coating enhances the filter's performance, ensuring the specified wavelength range is transmitted while other wavelengths are effectively blocked.

The filter's geometry is that of a thin lens, which is beneficial for applications where minimizing optical path length is crucial. This feature also aids in reducing the overall weight and complexity of the optical system.
