    SWIR Bandpass Filters are designed to pass the most common SWIR LED wavelengths. They are hard coated with a BBAR (broad- band anti-reflection) coating optimized for imaging in the SWIR. SWIR Filters can be used for various inspection tasks in the food and beverage, woodworking, textile or automotive industries.

    SWIR Longpass Filters are designed to pass a broad spectrum of SWIR wavelengths while blocking visible light. They are avail- able in both glass and acrylic options. LP1800 is made with a Germanium substrate and is also an ideal solution for protection windows, when (thermal) imaging up to 12 microns.

    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.
