67-124 50 mm Dia. Mounted Hard Coated OD 4.0 Notch Filter 355nm

The 67-124 is a Notch Filter with a 50 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed to block a narrow band of wavelengths while allowing others to pass through, making it an ideal choice for various applications where specific wavelengths need to be isolated or suppressed.

The filter's primary wavelength of interest is 355nm, which is located within the ultraviolet (UV) spectrum. This makes it particularly useful in UV-based applications, such as UV laser systems, spectroscopy, and fluorescence microscopy. The Notch Filter's design ensures that the 355nm wavelength is transmitted with high efficiency, while the notch region surrounding this wavelength is heavily attenuated.

The 67-124 filter is manufactured from UVFS Mal-1965, a material specifically chosen for its optical properties in the UV region. It has a circular shape, with a diameter of 50 mm and a thickness of 5 mm, providing a robust and compact form factor. The filter is also hard coated on both the front and back surfaces with EDM 67-106, enhancing its durability and resistance to environmental factors.

The physical data of the filter includes a center wavelength (CWL) of 355nm, which is the wavelength at which the filter's transmission is at its maximum. The filter's geometry and coating are designed to optimize its performance at this wavelength.
