13-086 12.5 mm Dia. Hoya ND-13 Absorptive Neutral Density Filter; OD 0.9 425-675nm

This is the 13-086 Neutral Density Filter from Hoya, available in a 12.5 mm diameter size. The filter is designed to reduce the intensity of light without altering its color composition, making it an ideal choice for various applications in photography, cinematography, and optical research.

The filter boasts an Optical Density (OD) of 0.9, which translates to a reduction of 75% of the light passing through it. This makes it suitable for use in bright lighting conditions, where controlling the amount of light is crucial. The OD value is consistent across the visible light spectrum, specifically within the 425-675nm range, ensuring predictable and uniform light reduction.

The filter is made from UVFS material with the Mal-1965 ID, and it features a thin lens shape with a thickness of 2.5mm. This design helps minimize optical distortions and ensures easy integration with your existing optical setup. The front and back surfaces of the filter are coated with the EDM 13-086 coating, which further enhances its performance and durability.
