FND-15C02-5 15 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm

The FND-15C02-5 is a high-quality Neutral Density Filter, unmounted with a 15 mm diameter and a thickness of 2mm, sourced from the renowned optical component manufacturer, OptoSigma. This filter is designed for use in the visible light spectrum, specifically between 400-700nm, making it suitable for a wide range of optical applications.

The filter is made from N-BK7, a high-grade borosilicate glass known for its excellent optical properties, including low auto-fluorescence, high homogeneity, and superior transmittance. This material is often the go-to choice for high-precision optical systems due to its exceptional performance and reliability.

The FND-15C02-5 features a reflective neutral density coating on both the front and back surfaces, identified as 'opt fnd-5'. This coating provides a uniform attenuation of light across the visible spectrum, enhancing the filter's ability to control light intensity without altering the color balance.

The filter's thin lens shape allows for easy integration into various optical systems, while its unmounted design provides flexibility in terms of housing and integration. According to the vendor's information, this item is currently in stock and available for immediate purchase.
