Each uncollimated, mounted LED consists of a single LED that has been mounted to the end of a heat sink. Most of the LEDs on this page have a heat sink housing that has the same 1.20" external diameter as an SM1 lens tube. Some of the LEDs offered below generate more heat during operation, and so are mounted to a larger heat sink with a Ø57.0 mm plastic housing for increased heat dissipation and thermal stability (indicated by the green rows in the table to the right). All the heat sinks are equipped with 6 mm deep internal SM1 (1.035"-40) threads for easy integration with other Thorlabs components. The larger heat sinks are also equipped with four 4-40 tapped holes for compatibility with 30 mm cage systems.
