Adjust your laser beam spot size, focal depth, and focal range by replacing different lenses.
Use Endurance DPSS laser spacer and change laser beam size, focal depth, and focal range.
4 different lenses in our laser lens pack for DPSSL
The lasers operate at TEM00, and cross-section profile of intensity within is beam is Gaussian. The graphs presented were obtained by calculation using the parameters of a real Gaussian beam.
Laser beam spot (left axis) vs. range from the laser to the lens.
Laser beam spot range: 11-500 um
The laser spot size is the 86% power level of the spot diameter. L1 is the distance from the laser (exit mirror) to the lens. (The spot diameter d (0.86P) is understood to be the diameter within which 86% of the beam power is contained.)
Laser focal range (left axis) vs. range from the laser to the lens.
Laser focal range: 20-150 mm
Laser focal depth (left axis) vs. range from the laser to the lens.
Laser beam spot range: 0.5-700 mm
The depth of focus is the length of the laser waist where the laser beam diverges by less than 2 times.
