Acton Optics & Coatings has introduced a new series of UV-NIR neutral density filters. Thanks to patented UV coating processes, these can include broadband UV-NIR neutral density filter performance down to 190 nm. The new ND filters, which are suitable for use with broadband sources like xenon, deuterium and tungsten halogen, have been designed to optimise the utility of precision optical systems, spectrometers and medical systems.
Various standard densities are available from 0.3 OD to 2.5 OD and the new filters can be stacked to create additional or deeper densities. The exclusive filter coatings can also be deposited on custom-sized substrates for OEM applications and, if required, can be designed for other optical density values.
