63-458 12.5 mm Dia. Hoya ND-25 Absorptive Neutral Density (OD 0.7) Color Filter

The 63-458 12.5 mm Dia. Hoya ND-25 Absorptive Neutral Density (OD 0.7) Color Filter is a high-quality optical component sourced from Edmund Optics. This filter is designed with a circular base shape and a diameter of 12.5 mm, making it suitable for a wide range of optical applications.

The filter is made from UVFS Mal-1965 material, a unique glass compound known for its excellent optical properties. It has a thickness of 3.1 mm, providing robustness and durability while maintaining minimal optical distortion. The ND-25 designation indicates a Neutral Density (ND) value of 0.7, which means it reduces the intensity of incident light by a factor of 2.8, without altering the color composition.

The filter features absorptive coatings on both the front and back surfaces, identified as EDM 63-458. These coatings are designed to enhance the filter's performance by absorbing unwanted light wavelengths, thereby improving image quality and contrast. The coating also provides scratch resistance, ensuring the filter maintains its performance over time.

The filter's geometry is shaped as a thin lens, which minimizes optical aberrations and distortions. This makes it an ideal choice for applications that require high-precision optical performance, such as imaging, spectroscopy, and beam shaping.
