The advanced use of a 820nm wavelength infrared laser diode is in the near infrared band and has the general characteristics of small IR laser light scattering and high transmittance infrared laser light source generation in the atmosphere. In practical precise dot indication and measuring works, high energy density infrared laser light source can be transmitted over a long distance, and has a certain penetration ability of some non-metallic materials. Owing to its invisible IR laser beam emission, it should only be integrating with night version device or equipment, thus it makes high precision measurement and indication for all night version illumination fields conveniently.
The real use of a 820nm infrared laser diode module is an invisible light laser device, which cannot be detected by the human eye directly. In fields such as security monitoring and military reconnaissance that require covert actions, IR laser light is not easy to be discovered by the target object, which can effectively protect the confidentiality of the action. The real use of this 820nm near infrared laser has high directivity and stability, and a small beam divergence angle. No matter it is pointing at close or long distance, it can achieve high precision focusing and dot positioning results, and good laser beam quality in real use.
In process of high precision IR beam and IR dot measuring work fields, 820nm infrared laser diode module applies a qualified glass coated lens and adjustable focus lens in front of beam aperture. It is able to penetrate biological tissues of a certain depth and cause relatively little damage to the tissues. As a result, on the basis of high penetration and high transmittance infrared laser light generation at long extending distances, in the medical field, this 820nm IR dot laser can be used in some scenes that require irradiation treatment or imaging of deep tissues, such as near-infrared phototherapy and biological tissue imaging.
In practical precise IR dot measuring work fields, comparing with those of high power and short wavelength laser devices, 820nm infrared laser diode module is relatively less harmful to the human eye. Under normal use, infrared laser light is not easy to cause permanent damage to the human eyes. However, whatever output power it is selected, users should only obey basic laser safety regulation so as to avoid eye exposure to eyes into the laser beam.
Applications:
Laser medical field: 820nm infrared laser is used for near infrared phototherapy, which is helpful for anti-inflammatory and analgesic effects on diseases such as arthritis and promotes tissue repair. When it is used for biological tissue imaging, it help doctors observe the internal tissues of the human body and assist in the diagnosis of diseases.
Security monitoring: At night or in low light environments, 820nm infrared laser light provides auxiliary lighting for surveillance cameras, allowing the camera to capture clear images without being easily detected, thereby improving the concealment and effectiveness of monitoring.
Military field: 820nm infrared laser diode module can be mounted and integrated onto a variety of weapons for night aiming of light weapons, used for military reconnaissance, target indication and other tasks.
Industrial detection: 820nm near infrared laser can be used for non-destructive testing of materials. Through infrared laser irradiation, the internal structure and defects of the material are analyzed. It can also be used for object identification and positioning in industrial automation production, using its high-precision beam for precise measurement and positioning.
