What makes a good job for engineers and professionals to make clear and precise enough cross line alignment for all optical experiments? Not able to rely on any prior cross line drawing or printing work, unaffected by long distance, high height and other complex working environments etc, it would be an efficient job to apply a high brightness light emitted tool of a 532nm green cross line laser module. It emits highly bright, intense and sensitive color green laser light from a middle wavelength of 532nm green DPSS laser system. Owing to its low laser beam divergence and special TEM00 laser beam mode, either it is pointing at close or long distance, this 532nm green cross laser alignment always assures high precision, quick response and highly precise two perpendicular green lines generation for all optical experiment works conveniently.
Usually 532nm green cross line laser module applies 532nm green DPSS laser within 5mW to 100mW and 150mW to 200mW output power. Configured with a metal heat sink cooling system inside a 16mm, 18.9mm and 26mm diameter anodized aluminum alloy housing tube, either adopting inner or external cooling system, it gets sufficient space leaving for tube heat dissipation, and achieves increasing laser beam stability under long term constant work of 10 hours per day. Owing to its high sensitivity and high brightness green light emission, equipped with low laser beam divergence of less than 1mrad and special TEM00 laser beam mode, green cross laser alignment gets ultra high fineness of 0.3mm at 10cm distance, 1mm to 2mm fineness at 2 meters work distance.
Cooperated with a qualified glass coated lens and adjustable focus optic lens in front of laser beam aperture, available with different fan angles of 10, 15 and 110 degree, this 532nm green cross line laser module generates high linear quality and highly straight horizontal and vertical references within 0.5 meter to 6 meters lengths, enabling bidirectional XY alignment in a single operation. After quite easy screw of laser beam aperture part, it gets narrow line width and excellent straightness, suitable for high-precision positioning, measurement, and calibration. Whenever green alignment laser gets easy connects with DC power supply, it is ready to use immediately, no complex optical path setup required, replacing traditional single-beam and beam splitting solutions. It is always compatible with optical platforms, stands, and fixtures, highly versatile for laboratory use.
