84-676 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 1400nm
The 84-676 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter is a specialized optical component designed for applications requiring long-pass filtering at 1400nm. This filter, sourced from Edmund Optics, is a circular element with a diameter of 25 mm and a thickness of 3 mm, making it suitable for a wide range of optical systems.
The filter is constructed from UVFS Mal-1965, a material known for its optical properties. It features a longpass cut-on wavelength of 1400nm, ensuring that shorter wavelengths are effectively filtered out. The cut-off wavelength is 0nm, indicating that all wavelengths shorter than the cut-on are blocked.
The 84-676 filter is coated on both the front and back surfaces with EDM 84-676, a coating that enhances its performance and durability. The shape of the filter is thin lens, which is a common design for optical elements intended for use in focused light paths.
This filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. The catalog number for this item is 84-676, making it easy to locate and order.
