NE05B Dia. 25 mm Absorptive ND Filter; Optical Density 0.5

The NE05B is a Neutral Density (ND) Filter, measuring 25 mm in diameter and 0.9 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 ideal tool for applications involving high-intensity light sources.

The NE05B filter features a coating of tho ne05a on both the front and back surfaces, contributing to its ability to uniformly attenuate light across the spectrum. This coating is specifically designed to maintain the filter's neutrality, ensuring that the light passing through it does not acquire any unwanted color casts.

The filter is constructed from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures the filter's durability and longevity, making it a reliable choice for various optical applications.

The NE05B filter is designed in a Thin Lens shape, which minimizes vignetting and ensures a consistent, uniform reduction of light intensity across the entire field of view. This feature makes it particularly suitable for use in imaging systems and other applications where a wide field of view is required.

The filter is currently in stock and available for purchase through the Thorlabs website, as indicated by its weblink status. For more detailed information or to place an order, users can follow the provided weblink.
