63-456 12.5 mm Dia. Hoya ND-70 Absorptive Neutral Density (OD 0.1) Color Filter; t=1.2 mm 400-700nm

The 63-456 is a 12.5 mm diameter color filter from Hoya, a renowned manufacturer in the optical industry. This filter is specifically designed as an absorptive Neutral Density (ND) filter with an Optical Density (OD) of 0.1. The ND-70 designation indicates that it reduces the light intensity by a factor of 10, offering a 1-stop reduction in light transmission.

This filter is part of Edmund Optics' extensive catalog, boasting a catalog number of 63-456 and a valid in-stock weblink status. The filter is circular in shape, made from UVFS MAL-1965 material, and has a thickness of 1.2 mm. It is coated on both the front and back surfaces with the EDM 63-456 coating, which is specifically designed for this filter.

The filter's geometry is defined by its 12.5 mm diameter, making it suitable for a wide range of optical applications. It is designed to transmit light within the 400-700nm wavelength range, which covers the visible light spectrum. The filter's thin lens shape ensures minimal distortion and maintains the integrity of the light path.
