AND-25C-50 25 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-25C-50 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 circular in shape, with a diameter of 25mm, making it suitable for a wide range of optical applications. It has 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 or mounts.

The AND-25C-50 features absorptive coatings on both the front and back surfaces, identified as 'opt and-50'. These coatings are specifically designed to provide a uniform attenuation of light across the visible spectrum, resulting in a neutral color balance. This makes the filter ideal for applications requiring light reduction without altering the color composition of the light.

The filter is constructed from UVFS Mal-1965, a high-quality optical glass material known for its excellent optical properties and durability. The filter's shape is designed in a Thin Lens format, minimizing optical aberrations and ensuring optimal performance.

According to the vendor's information, the filter is currently in stock and available for immediate purchase.
