86-121 12.5 mm Dia. Mounted Hard Coated OD 6.0 Notch Filter 632.8nm

The 86-121 is a Notch Filter, a type of optical filter that only transmits a narrow band of wavelengths while blocking others. This particular model, sourced from Edmund Optics, has a diameter of 12.5 mm and a thickness of 3.5 mm, making it compact and suitable for various applications.

The filter is designed to block wavelengths around 632.8 nm, with a Central Wavelength (CWL) also at 632.8 nm. This specificity in wavelength blocking makes it ideal for use in applications where precise wavelength control is necessary.

The 86-121 filter features hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. The coating also aids in reducing surface reflections, improving overall transmission and reducing unwanted light scatter.

The filter's shape is defined as a Thin Lens, which is a lens with a very small focal length compared to its diameter. This shape allows for minimal optical aberrations and distortions, ensuring the quality of the transmitted light.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its "Valid - in stock" weblink status. For more detailed information or to make a purchase, users can follow the provided weblink.
