NENIR513B Dia. 0.5 in NIR Absorptive ND Filter; OD 1.3

The NENIR513B is a Neutral Density (ND) Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a center wavelength of 1550nm. This filter is manufactured by Thorlabs, a renowned vendor known for their high-quality optical components. The filter is circular in shape, with a diameter of 12.7mm and a thickness of 0.8mm, making it suitable for a wide range of optical applications.

The NENIR513B features a special coating on both the front and back surfaces, denoted as 'tho nenir13b'. This coating is designed to provide a high level of absorption in the NIR spectrum, resulting in a Optical Density (OD) of 1.3. This means that the filter reduces the intensity of incident light by a factor of 20, making it an effective tool for controlling light levels in high-intensity NIR applications.

The filter is designed with a 'Thin Lens' shape, which helps to minimize optical aberrations and distortions, ensuring that the filtered light maintains its original quality as much as possible. The catalog number for this filter is NENIR513B, and it is currently in stock, as indicated by the 'Valid - in stock' status in the item data.
