65-809 50 mm Dia. Hoya ND-70 Absorptive Neutral Density (OD 0.15) Color Filter
The 65-809 50 mm Dia. Hoya ND-70 Absorptive Neutral Density (OD 0.15) Color Filter is a high-quality optical component sourced from Edmund Optics. This filter is designed with a circular shape, featuring a diameter of 50 mm and a thickness of 2.5 mm, making it suitable for a wide range of optical applications.
The filter is made from UVFS Mal-1965 material, a unique and specialized material that offers excellent optical performance. It is specifically designed for use in the visible light spectrum, with a central wavelength of 588 nm, making it ideal for applications that require precise control over light wavelengths.
The filter features a neutral density coating on both the front and back surfaces, identified as EDM 48-523. This coating provides a uniform attenuation of light across the entire spectral range, resulting in a reduction of light intensity without altering the color balance. The neutral density value of this filter is 0.15, also known as ND-70, which corresponds to a transmission of 12.5%.
The filter's geometry is shaped as a thin lens, which is beneficial for applications that require minimal optical path deviation. The catalog number for this item is 65-809, and it is currently in stock, as indicated by its weblink status. For more information, users can visit the provided weblink.
