NDUV40A Dia. 25 mm SM1-Threaded Mount; UVFS Reflective ND Filter; OD 4.0
The NDUV40A is a Neutral Density Filter from Thorlabs, designed with a circular shape and a diameter of 25 mm. This filter is built with a UVFS reflective coating, providing an Optical Density (OD) of 4.0, which is suitable for wavelengths of 300 nm. The NDUV40A features a thin lens shape and is equipped with an SM1-threaded mount for easy integration into optical systems.
The UVFS reflective coating on the NDUV40A is a unique feature that enhances the filter's performance. This coating is specifically designed to reflect UV light, making it ideal for applications that require UV light filtration. The OD 4.0 ensures that only a minimal amount of light passes through the filter, providing effective light control.
The NDUV40A's SM1-threaded mount adds to its versatility, allowing it to be easily integrated into various optical systems. This mount is compatible with other SM1-threaded components, providing a seamless fit and secure connection.
