AND-30C-13 30 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-30C-13 is a high-quality Neutral Density Filter, unmounted and round, with a diameter of 30 mm. This filter is designed for use in the visible light spectrum, specifically between 400-700nm. It is sourced from OptoSigma, a renowned vendor in the optical industry, and is available for purchase through their website.

This filter is of the Absorptive type, meaning it reduces the intensity of light by absorbing it rather than reflecting or scattering. The filter's coating, identified as 'opt and-13' on both the front and back, contributes to its absorptive properties. The geometry of the filter includes a thickness of 2mm, which aids in its durability and light reduction capabilities.

The filter's shape is described as 'Thin Lens', suggesting a design that minimizes optical aberrations and distortions. This makes it an ideal choice for applications that require high-resolution imaging and precise color reproduction.
