Product Details

OD 2.0 Longpass Filters are cost-effective filters with cut-on wavelengths ranging from 400 to 950nm. These longpass filters provide ≥85% transmission across a transmission band that extends out to 1600nm while providing OD 2.0 blocking across their rejection band. The back surface of each filter is coated with an antireflection (AR) coating, increasing the overall efficiency of the filter. OD 2.0 Longpass Filters can be combined with OD 2.0 Shortpass Filters to create custom bandpass filters to meet application requirements in the visible or near-infrared. These longpass filters are ideal for use in fluorescence applications or separating spectral orders, with the 6 x 6mm sized filters suitable for integration into optical instrumentation requiring cost-effective, lightweight filters.
