AND-25C-05 25 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-25C-05 is a 25 mm diameter Optical Glass Neutral Density Filter, specifically designed for use in the visible light spectrum, covering wavelengths from 400 to 700nm. This filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems.

The filter is produced by OptoSigma, a renowned vendor known for its high-quality optical elements. The product information indicates that the filter is currently in stock, and users can access further details and place orders via the provided weblink.

The filter is of the Neutral Density type, which means it reduces the intensity of light without altering its color composition. This is achieved through the absorptive coating, denoted as 'opt and-05' on both the front and back surfaces of the filter. This coating ensures a consistent attenuation of light across the visible spectrum.

The filter has a base shape of a circle, a standard geometry for many optical components. It has a thickness of 2mm, which contributes to its robustness and durability. The filter's shape is classified as a Thin Lens, suggesting that it has been designed to minimize optical aberrations and distortions.

The filter's material ID is UVFS MAL-1965, indicating the specific type of optical glass used in its construction. This information can be crucial for users who need to consider the material properties of their optical components.
