Colored-Glass Alternative Filters
from Newport Corporation

Our Colored-Glass Alternative filters are constructed using optical thin-film coating technology. Using Newport's patented Stabilife ® coating technology, many layers of refractory metal oxide film are deposited under vacuum in a precise sequence, defining the spectral signature of the filters.

Short and Long-Wave Pass Filters
from Newport Corporation

These shortpass and longpass filters are made with hard dielectric filter coatings, producing a very steep transition between passband and stopband making them far superior to absorptive colored glass filters. Steep transition slope. High rejection stop band. High transmission pass band. Excellent... [See More]
