65-017 80 mm Dia. Mounted OD 0.3 Absorptive Neutral Density Filter; t=5 mm 400-700nm

The 65-017 is a Neutral Density Filter, a type of optical component designed to reduce the intensity of incident light without altering its color composition. This particular model, sourced from Edmund Optics, boasts an 80 mm diameter and a thickness of 5 mm, making it suitable for a wide range of optical applications.

The filter's Neutral Density property is achieved through an Absorptive coating, which evenly absorbs light across the entire spectrum. This model is specifically designed for the 400-700nm range, ensuring consistent performance in the visible light spectrum. The coating is applied to both the front and back surfaces of the filter, further enhancing its light absorption capabilities.

The filter's geometry is defined by its Thin Lens shape, which is characterized by a central optical power region that gradually decreases in power towards the edges. This shape is designed to minimize optical aberrations and distortions, ensuring optimal image quality.

The 65-017 is available for purchase directly from the Edmund Optics website, where it is listed as being in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
