63-394 25 mm Dia. Non-Reflective Neutral Density Filter; OD 2.5 NIR 400-700nm
The 63-394 is a high-quality Neutral Density Filter, boasting a 25 mm diameter and a thickness of 1.5 mm, sourced from the renowned optical vendor, Edmund Optics. This filter is specifically designed for use within the visible light spectrum, with a central wavelength of 588 nm.
The filter is crafted from UVFS Mal-1965, a material known for its exceptional optical properties. Its non-reflective coating, EDM 63-384, is applied to both the front and back surfaces, further enhancing its performance by minimizing unwanted reflections and stray light.
The 63-394 filter is shaped as a thin lens, optimized for use in a variety of optical systems. It provides an Optical Density (OD) of 2.5 within the Near-Infrared (NIR) spectrum, specifically within the 400-700 nm range. This makes it an ideal choice for applications requiring precise control over light intensity, such as in photography, laser applications, or scientific research.
