Multi-cavity bandpass filter with extremely narrow bandwidth

Transmission above 85%

With bandwidths down to 0.1 nm, ultra-narrow bandpass filters from Alluxa also cover the requirements of current quantum technologies, where 0.2 to 0.5 nm are in demand. At the desired wavelength, they offer transmission of over 85% while blocking the remaining wavelengths with an optical density of >OD6. This makes these optics, distributed by LASER COMPONENTS, especially suitable for applications where the signal-to-noise ratio plays a decisive role. In addition to spectroscopy, plasma monitoring or fusion research, these include hydrogen-alpha (H-alpha) emission line filters for astronomy.

Despite the low bandwidth, layer designs with up to five cavities are used to filter out interfering secondary modes in lasers. Their number is crucial for the shape and edge steepness of the bandpass. Since complex interactions occur between these two parameters, LASER COMPONENTS recommends that details in the filter design be closely coordinated with the company's experts.
