NENIR503B Dia. 0.5 in NIR Absorptive ND Filter; OD 0.3
The NENIR503B 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 vendor in the optical components industry, and is available for purchase through their official website. The catalog number for this product is NENIR503B.
This ND filter is circular in shape, with a diameter of 12.7mm and a thickness of 0.5mm. The filter is made from UVFS material, identified by the Mal-1965 material ID. The NENIR503B filter features a thin lens shape, which is designed to minimize optical aberrations and ensure optimal performance.
The NENIR503B filter is coated with Thorlabs' proprietary NENIR03B coating on both the front and back surfaces. This coating is specifically designed to provide an Optical Density (OD) of 0.3 at the specified center wavelength. This OD value corresponds to a transmission of approximately 50% at the center wavelength, making it ideal for applications that require moderate light reduction.
The weblink status for the NENIR503B filter is "Valid - in stock", indicating that it is readily available for purchase and shipping. For more detailed information, users are encouraged to visit the official product webpage linked above.
