Edmund Optics has introduced new IR Neutral Density Filters that exhibit excellent linearity and are spectrally flat over a wide wavelength range of 2 to 14 µm. Made from precision germanium substrate, the filters are ideally suited for thermal and medical imaging. Their 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 filters achieve attenuation via a metal-alloy coating, which uses a combination of absorption and reflection to reach the stated transmittance value. The filters are available in 25 or 50 mm diameter with optical densities of 0.3, 0.5, 1.0, 2.0 and 3.0. IR Neutral Density Filter Kits are available in 25- and 50-mm-diameter versions and for all five optical densities.

PRESS RELEASE

Edmund Optics (EO), the premier provider of optical components, introduces their new IR Neutral Density Filters. Exhibiting excellent linearity, these filters are spectrally flat over a wide wavelength range of 2 to 14 µm. 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.

Neutral Density Filter Kits ideal for use with EO's filter wheels
Edmund Optics' IR Neutral Density Filters are available in five densities and two size options. The IR ND Filters are available in both 25 mm or 50 mm 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 25 mm diameter and 50 mm diameter versions. All five optical densities are also available as part of the EO Neutral Density Filter Kits. These unique kits are a great value, and are especially useful for integration with Edmund Optics' Filter Wheels.

Broadest selection of densities in the industry
Edmund Optics' IR Neutral Density Filters are extremely price competitive and offer the broadest selection of densities in the industry. With no waiting for tooling or custom design, these products are in stock with immediate availability for fast prototyping and testing. They offer an ideal solution for fast turnaround with excellent cost savings. Custom sizes and densities are available.

Edmund Optics (EO) is a leading producer of optics, imaging, and photonics technology for R&D, electronics, semiconductor, pharmaceutical, biomedical, and military markets around the globe.
