13-227 12.5 mm Dia. Hoya ND-0.3 Absorptive Neutral Density Filter; OD 1 750-1550nm

The 13-227 is a Neutral Density Filter, specifically designed for use in the near-infrared spectrum, with a diameter of 12.5 mm. This filter is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The filter is part of the NIR-II coated absorptive series, which is characterized by its ability to absorb light uniformly across the specified wavelength range. The ND-0.3 designation indicates that this filter reduces the light intensity by a factor of 1.3, offering a subtle yet effective means of controlling light levels in your optical system.

The filter is constructed with a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This is particularly beneficial in applications where high precision and accuracy are required.

The front and back surfaces of the filter are coated with the EDM 13-227 coating, which is specifically designed to enhance the filter's performance in the near-infrared spectrum. This coating also helps to protect the filter from environmental hazards, such as dust and moisture, thereby extending its lifespan.
