36-262 12.5 mm Diameter NIR Metallic Based Neutral Density Filter; OD 3.5 700-1100nm

The 36-262 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed for use in the Near-Infrared (NIR) spectrum, specifically catering to wavelengths between 700nm and 1100nm.

The filter boasts an Optical Density (OD) of 3.5, which is a measure of the filter's ability to reduce light intensity. This high OD value indicates that the filter can significantly decrease the amount of light passing through it, making it ideal for high-intensity light applications or for controlling exposure in imaging systems.

The filter is constructed from a Metallic Based material, which is known for its durability and stability in the NIR spectrum. This material also ensures consistent performance across the specified wavelength range.

In terms of geometry, the filter has a thickness of 1.5mm, which contributes to its overall robustness. The filter's circular shape is designed to fit into various optical systems, while the thin lens shape allows for easy integration into existing setups.

The filter's front and back surfaces are coated with the "edm 36-262" coating, which is specifically designed to enhance the filter's performance in the NIR spectrum. This coating ensures minimal reflection and scattering of light, thereby improving the overall efficiency of the optical system.
