Bright Light 515nm Green Laser Line Generator for Optical Experiment In order to make long time lasting precise line projection, not limited by long distance or high height, it enables efficient use of a 532nm green laser line generator. It is used as a light source for optical experiment to study optical phenomena such as light propagation, reflection, refraction, interference and diffraction. It can help students to better understand and master optical principles. Based on a qualified glass coated lens within 10 to 110 degree fan angle and glass window inside a durable housing tube, cooperated with adjustable focus optic lens, this laser line generator gets high density green laser light source and immediate conversion of increasing brightness and fineness green line projection in distance and other ambient environments. It brings users excellent line alignment measurement and alignment experiment for various optical experiments and teaching works etc. Technical data: Item: 5mW to 100mW, 150mW-200mW 515nm green laser line generator Laser class: IIIa, IIIb Optic lens: 10-110 degree glass coated lens Line length: 0.5 meter to 6 meters Adjustable focus: yes Power source: 5V, 9V, 12V 1000mA AC/DC adapter Serving lifetime: more than 8,000 hours Applications: optical experiments, physical demonstration, stage performance, scientific experiment https://www.berlinlasers.com/515nm-5mw-50mw-green-laser-line-generator
