NE2R02B Dia. 2 in Absorptive ND Filter; Optical Density 0.2

The NE2R02B is a Neutral Density (ND) Filter, measuring 2 inches in diameter, manufactured by Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an essential tool for various optical applications.

The filter is made from N-BK7 Schott, a high-quality borosilicate glass, ensuring durability and reliability. It boasts a diameter of 50.8 millimeters and a thickness of 1.4 millimeters, making it compatible with a wide range of optical systems.

The NE2R02B features a front and back coating of tho ne02a, an advanced absorptive coating that provides an optical density of 0.2 at a wavelength of 633 nanometers. This specific optical density reduces the intensity of light by a factor of 1.26, offering a subtle yet effective light reduction.

The filter's shape is designed in a thin lens format, which not only contributes to its lightweight nature but also allows for easy integration into various optical setups. The filter's geometry and coating are designed to minimize optical aberrations, ensuring high-quality image transmission.
