The 67-127 is a Notch Filter with a 50 mm diameter and a hard coated OD 4.0, specifically designed for use at a central wavelength of 514.5nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase through their website.
The Notch Filter is a type of optical filter that blocks a narrow band of wavelengths while allowing others to pass through. In this case, the 67-127 is designed to block the 514.5nm wavelength, making it an ideal choice for applications where this specific wavelength needs to be eliminated.
The filter is made from UVFS Mal-1965 material, ensuring durability and high-quality performance. It has a circular base shape and a thin lens shape, making it compatible with various optical systems. The geometry of the filter includes a diameter of 50mm and a thickness of 5mm, providing a balance between compactness and robustness.
The 67-127 filter features a front and back coating of EDM 67-109, which enhances its optical performance and durability. This coating ensures that the filter maintains its properties even under harsh conditions, making it suitable for a wide range of applications.
