PLH3D-XT-50 Specialized Engraving Laser Head

About PLH3D-XT-Series Engraving Laser Heads

PLH3D-XT-Series engraving laser heads were created as a series of specialized laser heads for engraving with extremely high resolution and cutting thing materials with ultra-thin line. PLH3D-XT-Series engraving laser heads are build based on PLH3D-6W-Series engraving laser heads. All advantages of PLH3D-6W-Series are inherited by PLH3D-XT-Series laser heads: versatility, compact dimensions, high-speed driver. Moreover all accessories from PLH3D-6W-Series are compatible with PLH3D-XT-Series.

The novelty of PLH3D-XT-Series laser heads is anamorphic optics. Thanks to anamorphic pair of prisms the beam spot-size is reduced significantly. Additionally new laser diode with significantly smaller emitting region and shorter wavelength is utilized in this series of laser head. Combination of anamorphic optics, small emitter laser diodes and short emitting wavelength result in incredible results.

Product Features

Microscopic Beam Spot

All of the laser heads from PLH3D-XT-Sereis are distinguished by microscopic beam spot. The microscopic beam spot is achieved thanks to anamorphic optics and aspheric collimation-focusing setup. PLH3D-XT-50 laser heads is achieving beam spot width below 50um and PLH3D-XT-10 engraving laser head is achieving beam spot size under 10um. For comparison typical human red blood cell is 5-10um and diameter of single human hair 50 – 20um. The spot size of PLH3D-10 is so small that it can be compared to length of a typical bacterium which is 1 – 10um.

Difference between the beam spot size of the engraving laser from PLH3D-XT Series

Short Wavelength - Highly Absorptive Light

Another distinguish feature of PLH3D-XT-Series laser head is short wavelength. PLH3D-XT-50 laser head emits 450nm and PLH3D-XT-10 laser head emits 405nm (violet color) light. Shorter wavelengths are generally more absorptive by different materials. On average 405 / 450nm light is tens times more absorptive comparing to IR laser. Shorter wavelengths results in higher energy of the photon. Therefore, process of engraving or cutting is more efficient comparing to alternative methods and high power levels are not necessary to achieve desirable effects.

High Power Density

As known power density is defined how much power is located in certain area. Typically it is specified in kilo wats over cm2 or mm2 (kW/cm2 or kW/mm2). This parameter is one of the most crucial parameter for cutting or engraving different materials. PLH3D-XT-Series laser heads are designed to achieve small beam-spot size the outcome of this proportional increase of the power density. Higher power density reveals new engraving and cutting possibilities. Additionally, engraving and cutting processes are significantly faster comparing to laser heads without anamorphic optics.
