NE260B 2 in x 2 in Absorptive ND Filter; Optical Density 6.0

The NE260B is a Neutral Density Filter from Thorlabs, measuring 2 inches by 2 inches with an optical density of 6.0. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an ideal choice for applications requiring high light attenuation.

The filter is made of n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. It boasts a thickness of 1.5 mm, ensuring durability and rigidity. The rectangular shape of the filter allows for versatile mounting options, while the thin lens shape facilitates easy integration into optical systems.

The NE260B features a coating of tho ne60a on both the front and back surfaces, providing superior neutral density performance. This coating ensures consistent attenuation across the spectral range, with a central wavelength of 633 nm. The coating also enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time.
