The 63-387 is a Neutral Density Filter with a 25 mm diameter, sourced from the reputable optical components vendor, Edmund Optics. This filter is designed to reduce light intensity without altering the color composition of the incident light, making it an ideal choice for various applications where control over light intensity is crucial.
The filter boasts a non-reflective coating, denoted as 'edm 63-377' on both the front and back surfaces. This coating significantly minimizes surface reflections, thereby enhancing transmission and reducing flare and ghosting effects. The neutral density filter has an Optical Density (OD) of 0.5, which corresponds to a transmission of approximately 70.8%.
The filter is crafted from UVFS Mal-1965 material, a durable and reliable option for optical components. It features a geometric design with a diameter of 25 mm and a thickness of 1.5 mm, classifying it as a Thin Lens. This design ensures minimal optical aberrations and distortions, contributing to the overall quality of the filtered light.
The 63-387 filter is specifically designed for the visible spectrum, with a central wavelength of 588 nm. It is also effective in the Near-Infrared (NIR) range, between 400 and 700 nm, making it a versatile option for a wide range of applications.
