NENIR504B Dia. 0.5 in NIR Absorptive ND Filter; OD 0.4
The NENIR504B is a Neutral Density (ND) Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a center wavelength of 1550nm. This filter is manufactured by Thorlabs, a leading global vendor known for its high-quality optical components. The catalog number for this item is NENIR504B, and it is currently in stock, as indicated by its weblink status.
This filter is circular in shape, with a diameter of 12.7mm and a thickness of 0.6mm, making it suitable for a wide range of optical applications. The filter's base shape is a Thin Lens, which is designed to minimize optical aberrations and distortions.
The NENIR504B features a specialized coating on both the front and back surfaces, known as tho nenir04b. This coating is an NIR absorptive coating, designed to reduce the intensity of light without altering its color balance. The coating provides an Optical Density (OD) of 0.4, which corresponds to a 10% transmission rate at the specified center wavelength.
