NENIR204B 2 in x 2 in Unmounted NIR Absorptive ND Filter; OD 0.4
The NENIR204B is a 2 in x 2 in Unmounted Neutral Density (ND) Filter, specifically designed for Near-Infrared (NIR) applications with a center wavelength of 1550 nm. This filter is sourced from Thorlabs, a renowned vendor known for its high-quality optical components.
The filter is made of UVFS material, identified by the Mal-1965 material ID. It features a thin lens shape, with a width, height, and thickness of 50.8 mm, 50.8 mm, and 0.6 mm respectively. This compact size makes it suitable for various optical systems where space is a constraint.
The NENIR204B filter boasts a coating on both the front and back surfaces, specifically the tho nenir04b coating. This coating provides an Optical Density (OD) of 0.4, which is equivalent to a transmission of 40%. This characteristic makes the filter ideal for applications requiring moderate light reduction.
The filter's information status is valid and in stock, ensuring its availability for immediate use. For more detailed information, you can refer to the vendor's website through the provided weblink.
