NENIR505B Dia. 0.5 in NIR Absorptive ND Filter; OD 0.5

The NENIR505B is a Neutral Density (ND) Filter, specifically designed for use in the near-infrared (NIR) spectrum with a wavelength of 1550 nm. This filter is manufactured by Thorlabs, a leading vendor in the field of optical components. The NENIR505B is a circular filter, with a diameter of 12.7 mm and a thickness of 0.8 mm, making it suitable for a wide range of optical applications.

The filter features a unique coating on both the front and back surfaces, denoted as 'tho nenir05b'. This coating is designed to provide an Optical Density (OD) of 0.5, which corresponds to a 70% transmission rate. This property makes the NENIR505B ideal for applications where light intensity needs to be reduced without significantly altering the color balance.

The NENIR505B filter is designed with a 'Thin Lens' shape, which is beneficial in maintaining the integrity of the optical path and minimizing unwanted distortions. The filter's geometry and coating make it a versatile tool for various NIR applications, including but not limited to, laser systems, biomedical imaging, and optical communication.
