AND-50S-13 50 x 50 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm
OptoSigma's AND-50S-13 is a high-quality Neutral Density Filter, designed to reduce the intensity of light without altering its color composition. This filter is unmounted, making it a versatile option for various optical setups.
The filter measures 50 x 50 mm, making it suitable for a wide range of applications. It has a thickness of 2 mm, ensuring durability and resistance to wear and tear. The base shape of the filter is rectangular, which is a common choice for many optical systems due to its ease of alignment and placement.
The filter is made from UVFS MAL-1965, a material known for its excellent optical properties. This material ensures high transmittance and low absorption, making it ideal for applications where light intensity needs to be carefully controlled.
The coating on both the front and back of the filter is 'opt and-13'. This coating enhances the filter's performance by reducing surface reflections and increasing transmittance. It also provides protection against environmental factors, ensuring the filter maintains its performance over time.
The filter is designed for visible light, with a wavelength of 550 nm. It is suitable for use in the 400-700 nm range, making it a versatile option for a wide range of optical systems.
