67-297 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 1150nm
The 67-297 is a Longpass Filter, a type of optical filter that transmits wavelengths longer than a specified value, while blocking shorter wavelengths. This particular model has a diameter of 25 mm and a thickness of 3 mm, making it suitable for a wide range of optical applications.
The filter is manufactured by Edmund Optics, a leading supplier of optical components, and features a traditional coating on both the front and back surfaces. This coating, identified as EDM 67-294, is designed to enhance the filter's performance and durability.
The cut-on wavelength for this filter is 1150 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength, on the other hand, is 0 nm, indicating that it blocks all wavelengths shorter than this value.
The filter is shaped as a Thin Lens, a type of lens with a very small focal length compared to its diameter. This shape, combined with the filter's other specifications, makes it a versatile component in various optical systems.
