The FNG0513 is a Neutral Density Filter with a 12.5 mm diameter, sourced from Knight Optical. This filter is designed to reduce the intensity of light without altering its color composition, making it ideal for applications where light intensity needs to be managed.
The filter is made of UVFS Mal-1965 material, a type of glass known for its optical properties. It has a wavelength of 546nm, which is within the visible light spectrum. This specific wavelength is often used in applications such as colorimetry and fluorescence microscopy.
The FNG0513 features a circular shape and a thin lens design, with a thickness of 4.1mm. This makes it suitable for use in systems where space is a constraint. The filter is coated on both the front and back with the Kni FNG05 coating, which likely enhances its performance and durability.
This filter is currently in stock and available for purchase on Knight Optical's website. It is a versatile and reliable option for anyone in need of a high-quality Neutral Density Filter.
