The AND-10S-10 is a Neutral Density Filter, specifically an Absorptive Neutral Density Filter, offered by OptoSigma. This filter is unmounted and has a base shape of a rectangle, with dimensions of 10 x 10 mm. The filter is designed for use in the visible light spectrum, specifically between 400-700nm.
The filter's thickness is 2mm, which is relatively thin, making it suitable for various applications. The coating on both the front and back of the filter is 'opt and-10', which is a specific coating used by OptoSigma for their Neutral Density Filters. This coating aids in the filter's functionality and durability.
The filter's geometry is that of a Thin Lens, which is a type of lens where the thickness of the lens is less than or equal to the diameter of the lens. This geometry is often used in optical systems where a thin lens is desirable for minimizing optical aberrations.
