67-121 25 mm Dia. Mounted Hard Coated OD 4.0 Notch Filter 785nm

The 67-121 is a 25 mm diameter Notch Filter, specifically designed to block a narrow band of wavelengths around 785nm while transmitting wavelengths outside this range. This filter is manufactured by Edmund Optics, a leading supplier of optical components. The filter is mounted and hard coated for durability, with an outer diameter of 4.0 and a thickness of 5.0 mm.

The Notch Filter is a type of optical filter that only allows a narrow band of wavelengths to pass through while blocking others. This particular filter is designed to block the 785nm wavelength, making it ideal for applications where this wavelength needs to be eliminated. The filter's thin lens shape ensures easy integration into optical systems.

The filter's coating is another crucial aspect. It features the EDM 67-112 coating on both the front and back surfaces, enhancing its performance and durability. This coating helps to reduce reflections and increase transmission, ensuring optimal performance in your optical system.

The 67-121 filter is currently in stock and available for purchase through the Edmund Optics website. For more detailed specifications and purchasing information, please refer to the provided weblink.
