NENIR05A-C Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; SM1-Threaded Mount; 1050 - 1700nm; OD 0.5 AR 1050-1700nm
The NENIR05A-C is a Neutral Density Filter, specifically designed for use in the 1050 - 1700nm wavelength range. This filter, offered by Thorlabs, is a crucial component in various optical systems where light intensity needs to be controlled or reduced without altering the color composition.
The filter boasts a circular shape with a diameter of 25 mm and a thickness of 0.8 mm, making it compatible with many optical systems. It features an SM1-threaded mount, which ensures secure and easy installation. The NENIR05A-C is coated with AR (Anti-Reflective) coatings on both the front and back surfaces, specifically designed for the 1050 - 1700nm wavelength range. This coating reduces unwanted reflections and increases transmission, thereby enhancing the overall performance of the optical system.
The NENIR05A-C provides an Optical Density (OD) of 0.5 at 1550nm, which is a measure of the filter's ability to reduce light intensity. This specific OD value indicates that the filter reduces the light intensity by a factor of 1.82, offering a significant yet controlled reduction in light intensity.
