NENIR60B Dia. 25 mm Unmounted NIR Absorptive ND Filter; OD 6.0
The NENIR60B is a circular Neutral Density Filter, with a diameter of 25 mm and a thickness of 2.8 mm, sourced from Thorlabs. This unmounted filter is designed for use in the near-infrared (NIR) spectrum, specifically at a wavelength of 1550 nm. The filter features a thin lens shape and is made from UVFS material, identified as "mal- 1965".
The NENIR60B filter boasts a high optical density (OD) of 6.0, which significantly reduces the intensity of light passing through it. This makes it an ideal choice for applications that require substantial light attenuation, such as high-power laser systems. The filter's coating, denoted as "tho nenir60b" on both the front and back surfaces, further enhances its light absorption capabilities.
The filter's catalog number, NENIR60B, can be used to access more information or to make a purchase from Thorlabs' official website. The current status of the filter, as per the provided data, is "Valid - in stock", indicating its immediate availability.
