NDUV20A Dia. 25 mm SM1-Threaded Mount; UVFS Reflective ND Filter; OD 2.0
The NDUV20A is a Neutral Density Filter from Thorlabs, designed with a circular shape and a diameter of 25 mm. This filter features a UVFS reflective coating on both the front and back, with an Optical Density (OD) of 2.0. The NDUV20A is compatible with SM1-threaded mounts, making it a versatile option for various optical applications.
The UVFS reflective coating on the NDUV20A is designed to provide high transmission and low reflection across a wide range of wavelengths. This coating is particularly useful in applications where minimal absorption and scattering are required. The OD of 2.0 indicates that the filter reduces the light intensity by a factor of 100, making it an excellent choice for high-intensity light sources.
The NDUV20A has a thickness of 1 mm, which contributes to its durability and resistance to mechanical stress. This filter is designed with a thin lens shape, ensuring easy integration into optical systems and minimizing the risk of vignetting.
Thorlabs, the vendor of this product, is a reputable manufacturer of optical components, known for their commitment to quality and innovation. The NDUV20A is currently in stock and available for purchase through the vendor's website, as indicated by its weblink status.
