63-398 12.5 mm Dia. Non-Reflective Neutral Density Filter; OD 0.6 NIR 700-1200nm

The 63-398 is a Neutral Density Filter with a diameter of 12.5 mm, 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 controlling light intensity is crucial.

The filter boasts a non-reflective coating, denoted as 'edm 63-398' on both the front and back surfaces. This coating enhances the filter's performance by minimizing surface reflections, thereby improving transmission efficiency and reducing unwanted glare. The coating also provides scratch resistance, ensuring the filter maintains its optical quality over time.

The 63-398 filter is specifically designed for use in the Near-Infrared (NIR) region, with a wavelength of 1064 nm. It has an Optical Density (OD) of 0.6, which corresponds to a transmission of approximately 32%. This makes it suitable for applications where moderate light reduction is required.

The filter is shaped as a Thin Lens, with a thickness of 1.5 mm. This design ensures minimal optical aberrations and distortions, contributing to the filter's high-quality performance. The filter's geometry, combined with its non-reflective coating and specific OD, makes it a versatile component for various optical systems.
