AND-30S-05 30 x 30 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-30S-05 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 absorbing light within the 400-700nm range.

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 made from UVFS MAL-1965 optical glass, a material known for its excellent optical properties and durability. The filter has a thickness of 2 mm, providing robustness and stability in its mounting.

The AND-30S-05 filter features absorptive coatings on both the front and back surfaces, identified as 'opt and-05'. These coatings are specifically designed to maintain neutrality across the visible spectrum, ensuring accurate and consistent light attenuation. The coating type contributes to the filter's high damage threshold, making it suitable for use in high-powered optical systems.

The filter is designed in a Thin Lens shape, which aids in minimizing unwanted optical effects such as aberrations and distortions. This feature enhances the filter's performance in precision optical systems.
