AND-50S-70 50 x 50 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-50S-70 is a high-quality Neutral Density Filter, offered by the renowned optical components manufacturer, OptoSigma. This filter is designed for use in the visible light spectrum, specifically covering the wavelength range of 400-700nm.

The filter is rectangular in shape, with dimensions of 50 x 50 mm, making it suitable for a wide range of optical applications. It boasts a thickness of 2mm, ensuring durability and stability during operation. The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems.

The AND-50S-70 features absorptive coatings on both the front and back surfaces, denoted as 'opt and-70'. These coatings are specifically designed to provide a neutral density of 0.70, which is equivalent to a 2.30 optical density. This makes the filter ideal for applications requiring a reduction in light intensity without altering the color balance of the incident light.

The filter is made from UVFS Mal-1965 optical glass, a material known for its excellent optical properties and durability. The geometry of the filter is defined as a 'Thin Lens', indicating its suitability for use in complex optical systems where minimal thickness is a critical factor.
