After constant technical innovation of 808nm infrared laser diode tech, not simply made into a simple infrared laser pointer, it is designed and manufactured into a more professional dot measuring tool of a 808nm infrared laser diode module. It emits near infrared light from a 808nm wavelength laser diode, which is invisible to the human eye, featuring a concentrated beam and stable output. Featured by ultra compact size and high duration metal housing tube design, it is easy to integrate into various automation systems, the 808nm infrared dot laser is commonly used in industrial vision positioning systems alongside infrared cameras and photoelectric sensors to provide non-contact reference markers.
Usually 808nm infrared laser diode module applies an import 808nm infrared laser diode within 100mW to 500mW as its beam emitting source. It produces no visible glare and does not interfere with manual visual tasks; the marker point is detectable only by infrared cameras. When it is required to make long operating time lasted dot generation, it applies a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube. When 808nm infrared dot laser adopts different dimension tube design, after leaving sufficient space for tube heat dissipation, it not only gets superior nice heat dissipation, but also maintains ultra clear and stable infrared reference dot projection under wide range operating temperature fluctuation, bears mechanical shaking and calibration as well. 
On condition that 808nm infrared laser diode module adopts a qualified glass coated lens and adjustable focus optic lens designs, it can easily achieve high beam concentration, features a small size infrared reference dot projection and high positioning accuracy, effectively minimizing positioning errors. 808nm infrared laser light emission is resistant to ambient light interference. When paired with the appropriate infrared filter, it filters out ambient visible light, ensuring stable positioning even under strong light conditions. When 808nm infrared dot laser alignment gets immediately concentrated infrared light source, it can easily convert into an increasing accuracy and brightness infrared dot projection at a long extending distance easily. 
According to the adoption of 16mm, 18.9mm and 26mm diameter metal housing tube design, this compact size tube made 808nm infrared laser diode module enables easy integration in tight spaces on robotic arms, fixtures, or machine tools. It is capable of continuous operation in dusty workshop environments, with minimal light spot drift and excellent stability. When laser users are aware potential thermal energy hurt to eyes and wearing correct infrared laser safety goggles, infrared alignment laser always brings engineers excellent dot alignment results for all industrial automated positioning fields, including robotic arm pick and place alignment, assembly line workpiece positioning, machine tool origin calibration, and material arrival detection works etc.
