NE510B Dia. 0.5 in Absorptive ND Filter; Optical Density 1.0

The NE510B is a Neutral Density (ND) Filter, measuring 0.5 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 ideal choice for applications requiring light level control.

The filter features a base shape of a circle, with a diameter of 12.7 millimeters and a thickness of 1.9 millimeters. This compact design ensures ease of integration into various optical systems. The filter material is n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.

The NE510B is coated with tho ne10a on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The optical density of the filter is 1.0, which translates to a 10% transmission rate at the specified wavelength of 633 nanometers.

The filter's shape is classified as a Thin Lens, indicating that it has been designed to minimize optical aberrations and distortions. This feature is crucial in applications demanding high-precision imaging and light control.
