445nm AR Coated Standard Glass Lens Assembly Summary
This 9mm diameter 445nm AR coated glass lens assembly fits standard 12mm O.D. diode modules. This fully-threaded lens is coated specifically for the 445nm wavelength and will provide a slight increase in laser light output over other lenses that are coated for a wavelength range of 405-445nm.
