We all know that 830nm laser diode is widely used in daily life, so do you know what uses it has? Let's take a look at it together.

Optical instruments, precision measurement

830nm is quite common in many measuring devices, such as optical encoders, interferometers and precision positioning systems.

830nm has a good response to silicon photodiode, and it is not as disturbed by ambient light as visible light.

Medical diagnostic equipment

You may not know that 830nm is still used in medical treatment, especially: blood oxygen monitoring (some models), percutaneous imaging, blood flow detection, near infrared phototherapy equipment.

Industrial positioning and alignment system

In SMT and industrial automation, 830nm laser spots or facula are often seen, which are used for alignment, edge detection and sliding platform positioning.

Laser bar code scanning and recognition

Many early bar code scanners used 780~830nm. Although 650nm red light is more popular now, many industrial scanners still use 830nm because of its mature recognition rate, more stable reflection on some materials and lower cost than 850nm VCSEL.

830nm laser diode is mainly used in measuring instruments, industrial positioning, medical detection, bar code scanning, and some research fields.
