IR Neural Density Filters

Edmund Optics has introduced a range of IR Neural Density Filters, which exhibit excellent linearity and are spectrally flat over a wide wavelength range of 2µm to 14µm.

Made from precision Germanium substrate, the filters are ideally suited for thermal and medical imaging. The broad spectral range makes these filters well-suited for eliminating hot spots in thermal images or attenuating a variety of IR laser sources, including CO2 and IR diode and quantum cascade lasers. The IR Neutral Density Filters achieve attenuation via a metal alloy coating, which uses a combination of absorption and reflection to reach the stated transmittance value.

Edmund Optics' IR Neutral Density Filters are available in five densities and two size options. The IR ND Filters are available in both 25mm or 50mm diameter models with optical densities of 0.3, 0.5, 1.0, 2.0 and 3.0. IR Neutral Density Filter Kits are available in 25mm diameter and 50mm diameter versions. All five optical densities are also available as part of the EO Neutral Density Filter Kits.
