3.46GA05-25 25mm Dia. 3460nm Sapphire Standard IR Bandpass Filter, HBW 140nm
The 3.46GA05-25 is a 25mm diameter Bandpass Filter, designed and manufactured by Andover Corporation. This filter is specifically engineered for Infrared (IR) applications, with a central wavelength of 3460nm. The filter is made from high-quality al2o3 sapphire2 material, ensuring durability and reliability in various environments.
The filter's geometry is defined by a 25mm diameter and a thickness of 1mm, making it a compact yet effective solution for IR applications. The cut-on wavelength is 3390nm, and the cut-off wavelength is 3530nm, providing a narrow bandwidth for precise IR detection.
The 3.46GA05-25 features a Thin Lens shape, which is designed to minimize optical aberrations and distortions, thereby enhancing the overall performance of the system. The filter is coated on both the front and back sides with the same coating (and 3.46ga05), ensuring consistent performance across all surfaces.
The filter is currently in stock and available for immediate purchase through the Andover Corporation's website. The link to the product page is provided in the item data for your convenience.
