13-260 50 mm Dia. Hoya ND-13 Absorptive Neutral Density Filter; OD 0.9 750-1550nm
The 13-260 is a 50 mm diameter Neutral Density Filter, specifically designed for use in the near-infrared spectrum, ranging from 750 to 1550nm. This filter is manufactured by Hoya, a renowned name in the optical industry, and is available through Edmund Optics.
The filter features an Optical Density (OD) of 0.9, which translates to a transmission of approximately 39%. This makes it ideal for applications where a significant reduction in light intensity is required, such as in high-powered laser systems or in high-exposure imaging applications.
The filter is designed in a circular shape, with a thickness of 2.5mm, and features a Thin Lens geometry. This design ensures minimal distortion and maintains the integrity of the incoming light path. The filter is coated on both the front and back surfaces with EDM 13-226, a specialized absorptive coating that enhances its performance in the near-infrared spectrum.
The 13-260 filter is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
