When users are getting serious need of highly clear and accurate dot alignment at great distance and high lighting, without the use of sunlight, it makes good job with a high brightness beam emitting tool of 100mW 532nm green laser diode module. It is projecting the most sensitive color and the most easily absorbed green laser light from middle wavelength of 532nm green DPSS laser system. The adoption of qualified glass coated lens and glass window are configured with durable anodized aluminum alloy housing tube, which is working well with high transmittance green laser light, and highly clear green dot alignment under moisture or dust as well. On basis of correct use of output power and freely adjusted laser beam focus and green dot projecting direction within three dimension, this green laser gets concentrated green laser light and efficient conversion of the most precise and the brightest green dot alignment at great distance of 25 meters and high lighting work fields perfectly.
