In order to make highly clear and precise dot indication for all raw material processing works, not relying on prior dot positioning work, it would be a better solution to operate a high energy concentration device of a 685nm red laser diode module. It applies advanced semiconductor 685nm red laser diode as core component, which emits 685nm red laser light by electrically exciting the recombination of electrons and holes to produce stimulated radiation. Cooperating with thermal emitting system and constant electric power source supply, it enables good direction, high penetration and high brightness red dot indication and measurement for all raw material processing works conveniently.

After the use of a qualified optic lens, such as a glass coated lens, this 685nm red laser diode module enables highly concentrated and highly penetrated red laser light emission. Cooperating with an adjustable focus optic lens design, it enables highly efficient concentration of red laser light source emission, good collimation and shape of the laser emitted by the laser diode. Either it is pointing at close or long distance, red laser beam is emitted at a specific angle and spot shape to ensure a highly clear and stable dot laser beam in use.

Connected with an AC/DC adapter, 685nm red laser diode module gets constant electric power source supply, thus obtains long time lasting red laser beam and red dot projection at various work distances. Equipped with APC, ACC driving circuit board design inside a durable anodized aluminum alloy housing tube. Within wide range operating temperature and storage temperature, it is applicable for various working environments, and maintains ultra stable and clear dot projection within long lasting work time and long serving lifetime in proper use. Being made with good sealing and heat dissipation, only after its proper mounting onto desired machine or device, red dot laser just enables no barrier and good directivity dot indication for multiple fields.

Key features:
685nm red laser outputs high energy red laser beams and concentrates energy in a small area, which is suitable for applications requiring high energy density.

High directivity. Red laser beam can be focused onto a very small red reference dot with excellent directivity, providing stable and accurate red dot indication for high precision processing and measurement.

Low divergence angle 685nm red laser keeps work with a high beam quality and performs well in long distance transmittance and focusing, which is not easy to diverge during transmission.

APC driving circuit board equipped 685nm red laser diode module enables stable output power and frequency for a quite long time, thus assuring high reliability of long term continuous operation and long serving lifetime of more than 8,000 hours.

Ultra compact structure made 685nm red laser diode module allows convenient installation and integration into various equipment, generating laser beam with high brightness and high visibility at a long work distance.
