FNM0225 25 mm Dia. Metallic Neutral Density Filter 546nm

The FNM0225 is a 25 mm diameter Neutral Density Filter, sourced from Knight Optical, a renowned vendor known for its extensive catalog of optical elements. This filter is designed to reduce the intensity of light without altering its color composition, making it an ideal choice for various applications in photography, cinematography, and scientific research.

The filter is made of N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. The base shape is circular, ensuring uniform light reduction across the entire field of view. The filter's geometry includes a diameter of 25 mm and a thickness of 2 mm, providing a robust and compact design.

The FNM0225 features a unique coating on both the front and back surfaces, identified as 'kni fnm02'. This coating enhances the filter's performance by reducing surface reflections and increasing transmission, thereby improving image quality and contrast. The shape of the filter is thin lens, further minimizing any potential optical aberrations.

The filter is designed to operate at a wavelength of 546nm, making it suitable for applications that require precise light control at this specific wavelength. The filter's 'in stock' status ensures quick delivery, making it an ideal choice for time-sensitive projects.
