87-735 12.5 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 520nm

The 87-735 is a Bandpass Filter with a diameter of 12.5 mm, manufactured by Edmund Optics. This filter is specifically designed for fluorescence applications, with a central wavelength (CWL) of 520nm and a bandwidth of 70nm.

The filter is made from UVFS Mal-1965 material, a common choice for optical applications due to its excellent transmission properties and durability. It has a thickness of 2mm, providing sufficient structural integrity for most applications.

The 87-735 features hard coatings on both the front and back surfaces, denoted as 'edm 87-735'. These coatings enhance the filter's durability and resistance to scratches and other forms of damage, making it suitable for use in challenging environments.

The filter's geometry is defined by a circular shape, a common choice for optical components due to its ease of integration into various systems. The cut-on wavelength is 485nm, and the cut-off wavelength is 555nm, providing a narrow passband around the CWL.
