NiSeries Neutral-Density Filters feature uniform attenuation simultaneously over the visible and SWIR range, from 400-2000nm, and can be used with CCD/CMOS and InGaAs camera systems. They have identical male and female threads, so they can be stacked with other Ni Filters to achieve various optical densities.

Pi1000 Series Wire-Grid Polarizer Filters are effective in both the visible and SWIR range, from 400-2000nm, and are useful for reducing specular glare. Wire-Grid Polarizer Filters can be mounted to the lens and LED light source, have an average contrast ratio of up to 8,000:1 and have an operating temperature rating of 100° C per 1,000 hours.
