Whenever line measuring work is processing at quite long work distances, it might be far more enough than formal hand reaching, it is always making good job for users to apply an intense beam emitting tool, such as a 445nm blue line laser module. Being made with the best quality separate crystal lens with different fan angles and constant power source supply, without any serious relying on manual labor force input, this laser line generator just brings users easy reaching and highly clear blue line generation for all raw material processing works. The advanced use of AC/DC adapter has just assured constant blue laser beam emission from a 445nm blue line laser module. It gets no need to make alkaline battery power source change, and also gets no limitation of long distance, high height and other hard reaching places etc. Supported by import 445nm blue laser diode within 50mW to 100mW, only after its correct use of 5V, 9V 1000mA DC power supply, this blue laser line generator always makes sure of highly visible blue laser beam emission within several miles, but also assures highly clear and fine blue line projection within the maximum work distance of 25 meters.Owing to the most special use of a separate crystal lens, whatever kind of working surface it is pointing, this 445nm blue line laser module is generating non Gaussian distribution blue laser light. It is also getting even finer and more visible blue reference line in use. When it projects high uniformity blue reference line, no matter it is pointing at close or long distance, it keeps work with the same line brightness from middle part towards both ends, thus this blue laser line generator is able to make extremely clear blue line projection for a lot of precise measuring work fields.Unless it is pointing under sunlight, 445nm non Gaussian beam blue line laser module allows the highest level of accuracy line alignment for special work fields, including laser show, laser displaying, decoration, military targeting and high tech etc. It gets the most compact size tube design of 16mm diameter anodized aluminum alloy housing tube, within freely installed distance of 3 meters, this blue alignment laser just makes easy and quick reaching of blue line source in use. After high attention to powerful laser radiation and reflection, and correct wearing of laser safety goggles, it brings users the most secured line measurement in long lasting use effectively.
