AND-40S-10 40 x 40 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-40S-10 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 40 x 40 mm, making it suitable for a wide range of optical applications. It has a thickness of 2mm, which adds to its durability and resistance to external pressures. The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems.

The AND-40S-10 features absorptive coatings on both the front and back surfaces, denoted as 'opt and-10'. These coatings are designed to uniformly reduce the intensity of incident light, without altering its color balance. This is achieved through the absorption of a portion of the light, which results in a neutral density effect.

The filter is made from UVFS Mal-1965, a high-quality optical glass material known for its excellent transmittance and clarity. This material is also resistant to environmental factors, ensuring the longevity and reliability of the filter.

The catalog number for this filter is AND-40S-10. It is currently in stock and available for purchase through the OptoSigma website. The link to the product page is provided for your convenience.
