13-087 12.5 mm Dia. Hoya ND-0.3 Absorptive Neutral Density Filter; OD 1 425-675nm

The 13-087 is a 12.5 mm diameter Neutral Density Filter, manufactured by Hoya, and available through Edmund Optics. This filter is designed with a circular base shape and a thin lens geometry, making it an ideal choice for applications requiring minimal thickness and weight.

The filter boasts a neutral density of 0.3, denoted as ND-0.3, which signifies a reduction in transmittance by a factor of 1.3. This feature is particularly beneficial in controlling the amount of light entering the optical system, thereby preventing overexposure and ensuring optimal image quality.

The 13-087 filter is coated on both the front and back surfaces with the EDM 13-087 coating. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby minimizing losses and improving overall system efficiency.

The filter is designed to operate within the wavelength range of 425-675nm, making it suitable for use in a wide range of applications within the visible spectrum. The catalog number for this item is 13-087, and it is currently in stock, as indicated by its weblink status.
