65-117 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 780nm
The 65-117 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 12.5 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which is known for its high-quality optical properties.
The filter's primary function is to allow light within a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, the Cut-On wavelength is 775 nm, and the Cut-Off wavelength is 785 nm, with the Central Wavelength at 780 nm. This makes it ideal for applications that require a narrow band of light around the 780 nm wavelength.
The filter's coating is another crucial aspect. Both the front and back surfaces of the filter are coated with the EDM 65-117 coating, which enhances its performance and durability. The filter's shape is that of a Thin Lens, further optimizing its light transmission capabilities.
The 65-117 is currently in stock and available for purchase through the Edmund Optics website. The catalog number for this item is 65-117, and the weblink provided leads directly to the product page for easy access and ordering.
