13-114 50 mm Dia. Hoya ND-50 Absorptive Neutral Density Filter; OD 0.2 425-675nm
The 13-114 is a 50 mm diameter Neutral Density Filter, manufactured by Hoya, a renowned name in the optical industry. This filter is designed with an Absorptive Neutral Density (ND) coating, specifically the EDM 13-114 on both the front and back surfaces. The absorptive ND filter functions by reducing the amount of light that enters the optical system without altering the color balance.
The filter's geometry includes a diameter of 50 mm and a thickness of 1.5 mm, making it compatible with various optical systems. The UVFS MAL-1965 material ID suggests that it is suitable for use in the visible light spectrum, specifically at a wavelength of 588 nm.
This filter is shaped as a Thin Lens, which is beneficial in reducing unwanted optical aberrations and improving overall image quality. The catalog number, 13-114, can be used for easy reference and tracking. The filter's current status is 'in stock', as indicated by the weblink status, and it can be found on the Edmund Optics website.
