12-005 12.5 mm Dia. Infrared (IR) Neutral Density Filter; OD 0.6 2-14µm

This is a 12.5 mm diameter Infrared (IR) Neutral Density Filter, catalog number 12-005, sourced from the renowned optical components vendor, Edmund Optics. The filter is designed to reduce the intensity of a broad range of wavelengths without altering the color composition of the light. It is specifically engineered for use in the infrared spectrum, with a central wavelength of 588 nm.

The filter boasts an Optical Density (OD) of 0.6, which corresponds to a transmission of approximately 32% (1/e) of the incident light. This makes it suitable for applications requiring moderate light attenuation. The filter's neutral density characteristic ensures that the attenuation is consistent across the entire spectral range, from 2 to 14 µm.

The filter is constructed from Germanium Burnett, a high-quality optical material known for its excellent transmission properties in the infrared region. The filter has a thin lens shape, with a thickness of 1 mm, making it suitable for use in various optical systems.

The front and back surfaces of the filter are coated with the "edm 12-005" coating, which enhances its performance and durability. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
