64-692 50 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=5mm 925nm
The 64-692 is a Longpass Filter, part of the extensive catalog of optical elements provided by Edmund Optics. This filter boasts a 50 mm diameter and a thickness of 5 mm, making it suitable for a wide range of applications. The Longpass Filter type implies that it allows light of longer wavelengths to pass through while blocking shorter wavelengths, a feature determined by its cut-on wavelength of 925 nm.
The filter's geometry is defined by its circular shape and thin lens design, which contributes to its versatility. The material ID, UVFS Mal-1965, provides specific information about the material composition, essential for understanding the filter's performance and compatibility with other optical elements.
The coating of this filter is a critical aspect of its functionality. Both the front and back surfaces are coated with EDM 64-678, a specific coating type that enhances the filter's performance and durability. This coating ensures the filter's longevity and maintains its optical properties over time.
The filter's physical data indicates that it is a 50 mm diameter filter with a 5 mm thickness, cut on at 925 nm. This information is crucial for designers and engineers looking for specific optical properties in their components.
