The 87-019 is a Multi-Notch Filter designed for use with Nd:YAG Lasers, specifically for the 355/532nm wavelength. This filter is sourced from Edmund Optics and is available for purchase on their website, with the current status indicating it is in stock.
The filter is a Circular Notch Filter, which means it is designed to block specific wavelengths while allowing others to pass through. In this case, it is designed to block the 355/532nm wavelength, making it ideal for use with Nd:YAG Lasers. The filter has a diameter of 25mm and a thickness of 3.5mm, making it suitable for a wide range of applications.
The filter features a Hard Coated OD 6.0 coating on both the front and back surfaces. This coating is designed to provide excellent durability and resistance to environmental factors, ensuring the filter maintains its performance over time. The coating also helps to reduce reflections, improving the overall efficiency of the system.
The filter is shaped as a Thin Lens, which means it has been designed to focus light. This can be beneficial in certain applications where a concentrated beam of light is required. The filter is made from UVFS Mal-1965, a material that is well-suited to optical applications due to its transparency and resistance to damage.
