AND-30S-40 30 x 30 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

OptoSigma's AND-30S-40 is a high-quality Neutral Density Filter, designed to minimize the intensity of light passing through the optical path without altering its color composition. This filter is specifically intended for use in the visible spectrum, with a central wavelength of 550nm.

The filter is rectangular in shape, with dimensions of 30 x 30 mm, making it suitable for a wide range of optical applications. It is constructed from UVFS MAL-1965 optical glass, a material known for its excellent optical properties and durability. The filter has a thickness of 2mm, which contributes to its robustness and stability in optical systems.

The filter features absorptive coatings on both the front and back surfaces, identified as 'opt and-40'. These coatings are designed to provide a uniform attenuation of light across the visible spectrum, resulting in a neutral color balance. The coating type ensures high damage threshold and low scatter, which is crucial for maintaining image quality and system performance.

The filter is unmounted, providing users with the flexibility to integrate it into their optical systems in a way that best suits their specific requirements. The 'Thin Lens' shape of the filter further enhances its compatibility with various optical setups.
