Basically 445nm wavelength blue laser diode and a qualified optic lens are integrated into a durable anodized aluminum alloy housing tube, which is designed and manufactured into a professional dot measuring tool of a 445nm blue dot laser module. Highly reflective materials, such as copper, stainless steel, and electroplated parts exhibit high blue light absorption and low reflectivity, resulting in clear, glare-free spot detection, superior to red light and reducing false positives. As a results, when blue dot laser alignment is selected with correct output power and operating voltage electric power source, it will be greatly helpful for engineers and professionals to make clear and precise dot indication for various raw material optical inspection works effectively.
Being made with a short wavelength of 445nm, the finished product of a blue dot laser module is easily producing tiny size blue reference dot diameter that meet the requirements for high-precision dimensional and defect location detection. When it gets wide range output power of 50mW to 100mW and 150mW to 500mW, according to the special use of a metal heat sink cooling system or separate cooling system for different output power range, blue dot laser alignment shows high blue light visibility in bright lighting environments at the inspection station, allowing for visual positioning without the need for shading.
The special adoption of a durable anodized aluminum alloy housing tube contains APC, ACC driving circuit board inside, thus 445nm blue dot laser module can bear wide operating temperature, superior nice heat dissipation and thermal conductivity, ultra stable and clear blue reference dot projection under any mechanical moving, shaking or calibration etc. in addition, it also supports TTL modulation, the blue dot laser alignment is switched synchronously with the inspection equipment and sensors, enabling automated intermittent spot detection. When it makes correct use of output power and operating voltage electric power source, it can bring engineers and professionals clear, bright and good direction blue dot indication for multiple optical inspection works.
Equipped with adjustable focus lens in front of laser beam aperture, the genuine use of a 445nm blue dot laser module allows freely adjusted laser dot diameter, allowing for small spots for microscopic inspection of small parts and large spots for overall inspection of large parts. One module is suitable for multiple product categories. It keeps work with low temperature drift and stable spot size during long-term operation ensure consistent batch inspection data. When blue alignment laser makes proper installation onto desired inspection station or device, it begins to make clear, no mistake and no barrier measurement for machine vision assisted calibration, optical component quality inspection, transmitting material detect inspection, highly reflective workpiece dimensional sampling inspection etc.
