13-102 25 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter; OD 0.7 425-675nm
The 13-102 25 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter is a high-quality optical component designed for a wide range of applications. Sourced from the renowned vendor Edmund Optics, this filter boasts a catalog number of 13-102 and is available for purchase through their official website.
This filter is a Neutral Density Filter, a type that reduces the intensity of all wavelengths of light equally, providing a uniform attenuation. The ND-25 designation indicates an Optical Density (OD) of 0.7, which corresponds to a 50% transmission of light. This makes it ideal for applications where a moderate reduction in light intensity is required.
The filter is designed for the visible spectrum, specifically between 425-675nm, making it suitable for use in applications where light within this range is of interest. The circular shape of the filter, with a diameter of 25mm, ensures easy integration into various optical systems.
The filter is constructed with a Thin Lens shape, which helps minimize optical aberrations and distortions. The geometry of the filter includes a thickness of 3.1mm, providing structural integrity and ease of handling.
The filter features a front and back coating of edm 13-102, which enhances its performance and durability. This coating helps reduce reflections, increase transmission, and protect the filter from environmental factors.
