64-629 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 675nm
The 64-629 is a Longpass Filter, part of the extensive catalog of optical elements offered by Edmund Optics. This filter has a circular base shape and is made of UVFS Mal-1965 material, which is renowned for its optical properties. The filter boasts a diameter of 25 mm and a thickness of 3 mm, making it suitable for a wide range of applications.
The 64-629 filter is designed to cut on at 675 nm, allowing light at this wavelength and longer to pass through while blocking shorter wavelengths. This feature makes it ideal for applications where the detection of longer wavelengths is crucial. The filter's physical data further supports this, with a cut off of 0 nm.
The filter is coated on both the front and back with EDM 64-621, a coating type known for its durability and performance. This coating ensures the filter's longevity and maintains its optical properties over time.
The 64-629 filter is shaped as a Thin Lens, a design that minimizes optical aberrations and enhances the overall performance of the filter. This feature, combined with its other specifications, makes the 64-629 an excellent choice for various applications in the field of optics.
