In various scientific research work fields, not able to limited by work distance and lighting occasions, it would always make a good job to apply a highly bright beam emitted tool of a 650nm red cross line laser module. It applies an import 650nm red laser diode and a qualified glass coated lens design inside its durable anodized aluminum alloy housing tube, which also gets constant electric power source supply. Basically it gets proper use of different dimension tube, and red light provides high visual visibility and clear imagining in both bright and dark environments, making red cross laser alignment suitable for various laboratory lighting conditions and eliminating the need for dark-field operation.
Being made with an import laser diode tech, owing to its mass production and long developing history, the finished product of a 650nm red cross line laser module also gets quite low production cost and ultra stable performance in those of long term continuous cross line projection works. Cooperated with a qualified glass coated lens with different fan angles of 10, 15 and 110 degree, it is projecting high linear quality and highly straight red cross line lengths from 0.5 meter to 6 length in distance. The crosshair accuracy is excellent, with a line width ≤0.2mm/2m and a positioning error <0.05mm, meeting experimental millimeter-level or even sub-millimeter-level accuracy requirements. Owing to its high attention to thermal emitting performance, this red cross laser alignment gets superior nice heat dissipation, and ultra stable and reliable two perpendicular red lines generation as long as 10 hours per day, unaffected by overheating and over current impact as well.
Being made with adjustable focus optic lens design in front of laser beam aperture, this low beam divergence made 650nm red cross line laser module maintains freely adjusted cross line thickness. Usually low power is suitable for eye-safe teaching demonstrations, while high power meets the needs of complex optical path penetration. The focus is continuously adjustable, with flexible working distances from 10cm to 10m, suitable for everything from close-range calibration to long-range optical path marking. This red cross laser alignment bears wide range operating temperature of -10℃ to 60℃, suitable for various laboratory equipment environments, protecting against electromagnetic and temperature interference. With the assistance of a laser alignment mounting bracket, it always saves experimental space and facilitating installation and debugging, providing easy reaching, good direction and noncontact red cross line source for all experimental works easily.
