Newport MKS Laser Beam Dump, 30 W/cm 2 Max Power Density, RMS Thread PL15

The PL15 Laser Beam Dumps is used to absorb incident light and capture unwanted laser beams. In the optics laboratory, they are used to stop stray laser beams to protect personel and equipment. In instrumentation, laser beam dumps and traps are used to contain a beam within a portion of the instrument.The anti-reflective property of a laser beam dump can be characterized by the apparent reflective factor. Incident light is reflected twice off a black cone whose reflection factor determines the observed reflection of the unit. The PL15 Beam Dump has a reflective factor of less than 10-4, fifty times more efficient than classical beam dumps.The active surface should be kept clean of dust, grease, and scratches to preserve the unit’s efficiency. To clean the active surface, disassemble the unit and gently wipe the surface with a soft clean tissue. Precaution should be taken to avoid concentric marks while cleaning. Reflectivity Factor Less Than 10-4 The anti-reflective property of a beam dump can be characterized by the apparent reflective factor. Incident light is reflected twice off a black cone whose reflection factor determines the observed reflection of the unit. For a maximum beam diameter of 0.59 in. (15 mm), the PL15 Laser Beam Dump has a reflective factor of less than 10-4, which is fifty times more efficient than classical laser beam traps. Easy to Maintain The active surface of a laser beam dump should be kept clean of dust, grease, and scratches to preserve the unit’s efficiency. To clean the active surface, disassemble the unit and gently wipe the surface with a soft clean tissue. Precaution should be taken to avoid concentric marks while cleaning.
