AND-50S-001 50 x 50 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-50S-001 is a 50 x 50 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter, specifically designed for use within the 400-700nm wavelength range. This filter is developed by OptoSigma, a renowned vendor known for their advanced optical elements.

The filter is of the Neutral Density type, which means it reduces the amount of light entering the optical system without altering the color composition. This is particularly useful in situations where the intensity of light needs to be managed, such as in photography or scientific research.

The filter is rectangular in shape, with dimensions of 50mm x 50mm, providing a substantial surface area for light interaction. It has a thickness of 2mm, which contributes to its durability and stability within an optical system.

The filter's coating is another crucial aspect. Both the front and back surfaces are coated with 'opt and-001', a coating that likely enhances the filter's performance and longevity. The specifics of this coating are not provided in the item data, but it is safe to assume that it aids in the filter's light absorption capabilities.

The filter's geometry is defined as a 'Thin Lens', suggesting that it is designed to minimize optical aberrations and distortions. This is particularly important in high-precision applications where image quality is paramount.
