13-108 25 mm Dia. Hoya ND-0.3 Absorptive Neutral Density Filter; OD 2.5 425-675nm

The 13-108 is a 25 mm diameter Neutral Density Filter, manufactured by Hoya and sourced from Edmund Optics. This filter is designed to reduce the intensity of light entering the optical path without altering its color composition. It is particularly useful in photography and videography, where controlling light intensity is crucial for achieving desired exposure levels and depth of field.

The filter boasts an Optical Density (OD) of 2.5, which corresponds to a transmission factor of 0.63%. This high OD value indicates that the filter is capable of blocking a significant amount of light, making it suitable for use in high-intensity lighting conditions. The wavelength range for this filter is 425-675nm, which covers a broad spectrum of visible light.

The filter is constructed with a Thin Lens shape, which minimizes optical aberrations and distortions. It features absorptive coatings on both the front and back surfaces, identified as EDM 13-091. These coatings enhance the filter's light absorption capabilities and contribute to its high OD value.
