The 64-613 is a 50 mm diameter Shortpass Filter with a thickness of 5mm, designed for optimal performance at a wavelength of 588nm. This filter, sourced from Edmund Optics, is a crucial component in various optical systems, particularly those requiring precise wavelength control.
The filter's primary function is to allow light transmission below a specified wavelength (675nm in this case) while blocking or attenuating light above this wavelength. This characteristic makes it ideal for applications such as fluorescence microscopy, where it's essential to isolate specific wavelength ranges.
The 64-613 filter features a Thin Lens shape, which is beneficial in systems where space is a constraint. Its circular geometry further enhances its versatility, making it compatible with a wide range of optical setups.
The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 64-597, a proprietary coating from Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
