In order to make precise and fine line alignment at various work distances, either it is pointing at close or long distance, it makes good job with a direct diode made Berlinlasers 650nm red line laser module. It is projecting moderate brightness red laser light directly from a 650nm red laser diode within 5mW to 100mW.
The unique use of a separate crystal lens and glass window are cooperating with high duration anodized aluminum alloy housing tube, this red line laser module is working well with the most preferred red laser light. It projects even finer and brighter red laser line from a formal plastic or glass coated lens. Only if it makes correct use of optic lens degree and output power, within freely installed distance of 3 meters, it makes no mistake line alignment for both industrial and high tech work perfectly.
