The 63-389 is a Neutral Density Filter with a 25 mm diameter and a thickness of 1.5 mm, sourced from the renowned optical component 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 that require light control, such as photography and laser applications.
The filter boasts a non-reflective coating on both the front and back surfaces, denoted as 'edm 63-379'. This coating minimizes surface reflections, thereby enhancing transmission and reducing unwanted glare. The coating also provides scratch resistance, ensuring the longevity and durability of the filter.
The 63-389 filter is specifically designed for the Near-Infrared (NIR) spectrum, with a wavelength range of 400-700nm. This makes it suitable for applications that involve NIR light, such as biomedical imaging, night vision, and surveillance.
The filter is shaped as a Thin Lens, which is advantageous in applications where minimizing optical path length is crucial. It is available for purchase directly from the vendor's website, with a current status of being in stock.
