NENIR550B Dia. 0.5 in NIR Absorptive ND Filter; OD 5.0
The NENIR550B is a Neutral Density (ND) Filter, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This filter is specifically engineered for use in the Near-Infrared (NIR) spectrum, with a center wavelength of 1550 nanometers.
The filter is circular in shape, with a diameter of 12.7 millimeters and a thickness of 2.3 millimeters, making it compatible with a wide range of optical systems. The NENIR550B features a Thin Lens shape, which is designed to minimize optical aberrations and distortions, ensuring optimal performance in your setup.
The filter's primary function is to reduce the intensity of light passing through it, with an Optical Density (OD) of 5.0. This is achieved through the use of a specialized coating on both the front and back surfaces of the filter, identified as 'tho nenir50b'. This coating is specifically designed to absorb NIR light, thereby reducing its intensity.
The NENIR550B is currently in stock and available for purchase through the Thorlabs website. For more information, including pricing and detailed specifications, please refer to the provided weblink.
