NE03B Dia. 25 mm Absorptive ND Filter; Optical Density 0.3

The NE03B is a Neutral Density (ND) Filter, measuring 25 mm in diameter and 2.3 mm in thickness, 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 NE03B filter features a coating of tho ne03a on both the front and back surfaces, which provides an optical density of 0.3. This specific optical density corresponds to a reduction factor of approximately 50% for the incident light, allowing for precise control over light intensity.

This circular filter boasts a base shape made of n-bk7 schott material, a popular choice in optical applications due to its excellent homogeneity, low auto-fluorescence, and high damage threshold. The thin lens shape of the NE03B filter ensures minimal distortion and maintains the overall integrity of the optical system.

The NE03B filter is currently in stock and available through the vendor's website, with the catalog number NE03B. Users can access additional information and place orders by visiting the provided weblink, which has been verified as valid at the time of this description.
