FND-25C02-5 25 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm
This is the FND-25C02-5, a 25 mm diameter, unmounted Neutral Density Filter from OptoSigma. The filter is made of N-BK7, a high-quality glass material from Schott, ensuring durability and reliability. It is designed for use in the visible light spectrum, specifically between 400 and 700 nanometers.
The filter features a reflective neutral density coating on both the front and back surfaces, identified as 'opt fnd-5'. This coating is uniform across the entire surface, providing a consistent attenuation of light. The thickness of the filter is 2 millimeters, which is considered thin in the context of optical components, making it suitable for applications where space is a constraint.
The FND-25C02-5 is currently in stock and available for immediate purchase. For more information, you can refer to the vendor's website through the provided link. This filter is a versatile and high-performing option for various optical applications, offering precise light control in the visible spectrum.
