TO-18 Laser Diode Metal Housing with Lens [12x45mm]

Description:
TO-18 Laser Diode Metal Housing with Lens [12x45mm] is a modular cylindrical case which is specialized for housing and handling a TO-18 (5.6mm) packaged laser diode and its driver board with batteries. The main body is a 12mm x 45mm cylinder with a detachable bottom and a detachable head (plastic lens and lens cap included). These copper-plated nickel parts have been precision machined, so this case is nice and robust.
A laser diode, (LD), an injection laser diode (ILD), or diode laser is an especial semiconductor P-N junction, to emit coherent light with a narrow spectrum. Two big challenges of laser diodes projects are proper heat control (heat dissipation) and proper powering supply (diode driving). Therefore laser diode should be attached on the heat conductive case (copper, aluminum, and so on) to export diode heat producing into this body. Also, an optical lens is placed on the body to focus the laser beam. 
High-power laser diodes are used in industrial works such as heat treating, cladding, seam welding and for pumping other lasers, such as diode-pumped solid-state lasers.
