13-182 50 mm Dia. Hoya ND-50 Absorptive Neutral Density Filter; OD 0.2 600-1050nm

The 13-182 50 mm Dia. Hoya ND-50 Absorptive Neutral Density Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from the renowned optical vendor Edmund Optics, this filter boasts a catalog number of 13-182 and is available for purchase directly from their website.

This filter is specifically designed as a Neutral Density Filter, which means it reduces the intensity of all wavelengths of light equally, providing a uniform attenuation of light across the visible and near-infrared spectrum. The ND-50 designation indicates that this filter has an Optical Density (OD) of 0.2, which corresponds to a transmission of approximately 63%.

The filter is circular in shape, with a diameter of 50 mm and a thickness of 1.5 mm, making it suitable for use in a variety of optical systems. The material ID for this filter is UVFS MAL-1965, although the specific composition of the material is not provided in the item data.

The filter features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This is particularly important in applications where high-precision optical performance is required.

Both the front and back surfaces of the filter are coated with the EDM 13-182 coating, which is likely designed to enhance the filter's performance and durability. However, the specific details of this coating are not provided in the item data.
