Using our Ion Beam Sputtering (IBS) technology, Excelitas’ edge filters provide bandpass and sharp edge filters that have exceptional wavelength stability for ambient temperature and humidity changes. This highly controlled deposition process ensures that these edge filters are manufactured to meet the most demanding spectral requirements. Furthermore, our infrared edge filters provide the optimum transmittance, high blocking, and offer sharp spectral edges.
Excelitas is home to the world’s largest concentration of IBS optical coating technology, with more than two dozen IBS Coating systems in operation today. As pioneers of the commercial use of IBS Coatings in the late 1980s, our IBS technology produces thin films with exceptionally low scatter and absorption and high mechanical and environmental durability. Utilizing primarily metal oxide materials, IBS is used to produce films that function from the UV through the Mid IR (up to 6 μm) for filter applications.
