The genuine use of a 808nm infrared line laser module applies advanced 808nm infrared laser diode tech and a qualified glass coated lens inside its durable housing tube. It is working well with intense and powerful invisible infrared laser light emission, needs to be observed with infrared receiving equipment or night vision devices), which will not interfere with the doctor's vision, and is especially suitable for surgical scenes that require focused vision. The infrared line emitted from a IR laser line generator is thin and has high straightness, which can meet the medical field's demand for millimeter-level or even sub-millimeter-level accuracy. 
The genuine use of a 808nm infrared line laser module applies an import 808nm infrared laser diode within 5mW to 500mW as its beam emitting source, which is cooperating with a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube. In those of long time lasting IR line projection work, it gets superior nice thermal emitting and thermal conductivity, and increasing stability infrared line emission as long as 8 to 10 hours per day. For the most important of all, this laser line generator always bears wide range operating temperature, different humidity and harsh working occasions of mechanical moving, shocking or calibration as well. 
According to the adoption of a glass coated lens within 10 to 110 degree fan angle in front of beam aperture, this 808nm infrared line laser module is projecting high density Gaussian IR laser beam, high linear quality and highly straight infrared reference line projection with different line lengths. It should only be selected with correct output power and optic lens fan angle, which is also not effected by operating room lights, such as strong light from surgical lights, and can still output the baseline stably in complex lighting environments. In those of laser medical treatment works, owing to its selection of low power of only 5mW, this infrared laser line generator meets medical laser safety standards (usually below Class IIIa), has low energy, and will not cause thermal or photochemical damage to human tissue.
Every time 808nm infrared line laser module gets proper connects with AC/DC adapter, it just makes constant infrared laser beam and infrared line generation from beam aperture immediately. It can avoid direct contact with patients or instruments, reduce the risk of cross-infection, and will not affect the operation of surgical instruments. Owing to its special use of 16mm and 26mm diameter housing tube design, this ultra compact structure made IR laser line generator can be flexibly installed on medical equipment such as surgical microscopes and robotic arms, and is suitable for a variety of medical scenarios. In various medical treatment fields, it is an important auxiliary tool in the medical field to improve operational accuracy and ensure treatment safety. Especially in scenarios that require precise anatomical positioning, it can effectively reduce operational difficulty and risk.
808nm infrared line laser module is mainly used for precise positioning, guidance and auxiliary operation in the medical field. Its major application scenarios are as follows:
Surgical positioning guidance: In orthopedic surgery (such as fracture reduction, spinal surgery), the straight infrared alignment laser line can mark the baseline of the bone anatomical structure, assist doctors in determining the incision position and the placement direction of implants (such as steel plates and screws), and improve surgical accuracy.
Rehabilitation therapy assistance: 808nm infrared laser line generator is used in rehabilitation training to mark the limb movement trajectory (such as joint range of motion, gait correction path), help patients standardize movements, and assist therapists in evaluating rehabilitation effects.
Medical equipment calibration: In the installation and commissioning of radiotherapy equipment and imaging equipment (such as CT, MRI), as a straight line reference, ensure that the coaxiality and parallelism of the mechanical structure of the equipment meet the accuracy requirements.
Tissue cutting marking: In superficial tissue cutting in dermatology and surgery, infrared alignment laser can define the cutting boundary and reduce surgical errors.
