FBR-ND20 25.4 mm Dia. Optical Crown Glass Metallic Neutral Density Filter 400-2000nm

The FBR-ND20 is a high-quality Neutral Density Filter, designed and manufactured by MKS/Newport. This filter is part of the FBR series, known for its precision and durability. The FBR-ND20 is a circular filter, with a diameter of 25.4 mm and a thickness of 3 mm, making it compatible with a wide range of optical systems.

The filter is made of optical crown glass, a material renowned for its excellent optical properties and resistance to environmental factors. This ensures the filter maintains its performance over time, even with regular use. The filter's neutral density coating, applied to both the front and back surfaces, provides a uniform attenuation of light across the entire spectral range of 400-2000nm. This makes the FBR-ND20 ideal for applications requiring precise light control, such as in scientific research, photography, and laser applications.

The filter's thin lens shape and the high-quality coating contribute to minimal optical distortion and excellent light transmission. The FBR-ND20 is currently in stock and available for immediate purchase through the Newport website. With its robust design, versatile compatibility, and reliable performance, the FBR-ND20 is a excellent choice for any application requiring precise light control.
