ND502A Dia. 0.5 in ND Reflective Filter; SM05-Threaded Mount; Optical Density 0.2
The ND502A is a Neutral Density Filter from Thorlabs, designed with a circular base shape and a diameter of 0.5 inches. It is made from n-bk7 Schott material, a popular choice for its excellent optical properties and durability. The filter features a thin lens shape, ensuring minimal distortion and a compact design.
The ND502A boasts a wavelength of 633 nanometers, making it suitable for a wide range of applications that require precise light control. It comes with a SM05-threaded mount, providing a secure and stable connection to other optical components in your setup.
The filter's coating is another notable feature. Both the front and back are coated with tho nd02, a reflective coating that enhances the filter's performance and longevity. This coating contributes to the filter's optical density of 0.2, which is ideal for applications that require subtle light reduction.
