NENIR10B Dia. 25 mm Unmounted NIR Absorptive ND Filter; OD 1.0
The NENIR10B is a circular Neutral Density Filter, unmounted, with a diameter of 25 mm and a thickness of 1.6 mm. This filter is designed for use in the Near-Infrared (NIR) region, specifically at a wavelength of 1550 nm. The filter is manufactured by Thorlabs, a leading vendor in the field of optical components.
The NENIR10B features a special coating, denoted as 'tho nenir10b' on both the front and back surfaces. This coating is designed to absorb specific wavelengths of light, thereby reducing the overall intensity of the light passing through the filter. The result is a more controlled and manageable light source, which is particularly beneficial in high-intensity NIR applications.
The filter's geometry is shaped as a Thin Lens, which is a type of lens with a very small focal length compared to its diameter. This design allows for minimal optical aberrations and distortions, ensuring that the light passing through the filter remains as close to its original form as possible.
The filter is currently in stock and available for purchase through the Thorlabs website, as indicated by the 'weblink status' field in the item data. For more information, including pricing and availability, please refer to the provided weblink.
