The 64-678 is a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths, from the renowned vendor Edmund Optics. This particular model boasts a 12.5 mm diameter and a thickness of 1.5 mm, making it suitable for a wide range of optical applications.
The filter is designed with a cut-on wavelength of 925 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength, which is the point at which the filter starts to block light, is 0 nm. This specificity in wavelength management makes the 64-678 an ideal choice for applications requiring precise wavelength control.
The 64-678 features a Thin Lens shape, enhancing its functionality in various optical systems. The filter's front and back are coated with "edm 64-678", a proprietary coating from Edmund Optics that likely enhances the filter's performance and durability.
