An endoscope laser light filter assembly includes a filter support having opposing first and second sides, one or more circumferential flanges, and a laser light filter. The one or more circumferential flanges are positioned on the first side of the filter support and are displaced from the filter support along a central axis. The laser light filter is supported on the second side of the filter support.

A watertube boiler system is disclosed which provides a plurality of radiant burners mounted within a housing in parallel, spaced-apart relationship. Individual burners are encircled by heat cells comprised of watertube coils which are in tangential juxtaposed relationship achieving a high view factor to the burner surfaces. Premixed fuel and air combusts on the outer surfaces of the burners which radiate energy to the tubes forming the heat cells. The ratio of combustion surface area to heat cell volume is within an optimum range for minimizing NOX and CO emissions.
