84-103 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 628nm

The 84-103 is a Bandpass Filter with a diameter of 25 mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for fluorescence applications, featuring a center wavelength of 628nm and a 32nm bandwidth.

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 2 mm, providing sufficient structural integrity while maintaining minimal optical path differences.

The 84-103 filter is designed to pass light within the specified bandwidth (609nm to 647nm) while blocking other wavelengths. This is particularly useful in fluorescence microscopy, where specific excitation and emission wavelengths need to be isolated.

The filter features hard coating on both the front and back surfaces, denoted as 'edm 84-087'. This coating enhances the filter's durability and resistance to scratches, making it suitable for rigorous laboratory or industrial use.

The filter's shape is described as 'Thin Lens', indicating that it may have some lens-like properties, such as a curved surface for focusing or collimating light. However, this is not explicitly stated in the provided data, so it's best to consult the vendor for more detailed information.
