NE2R03B Dia. 2 in Absorptive ND Filter; Optical Density 0.3
The NE2R03B is a Neutral Density (ND) Filter, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This particular model boasts a circular shape, with a diameter of 50.8 millimeters and a thickness of 2.3 millimeters, making it compatible with a wide range of optical systems.
The filter's primary function is to reduce the intensity of light, without altering its color composition, by absorbing a portion of the incident light. This is achieved through the application of a specialized coating, known as tho ne03a, on both the front and back surfaces. This coating is responsible for the filter's optical density of 0.3, which signifies a 23% transmission of light.
The NE2R03B is crafted from N-BK7 Schott, a high-quality optical glass, ensuring excellent optical performance. The filter's geometry is shaped as a thin lens, further enhancing its compatibility with various optical setups.
