We all know that QSI laser diodes are widely used in daily use, so do you know where to buy QSI laser diodes?

With the wide application of laser diode in industry, medical treatment, ranging, scanning, bar code recognition and other fields, selecting reliable suppliers has become the key to ensure product quality and stability. As a well-known composite semiconductor manufacturer in Korea, QSI produces infrared and visible laser diodes with multiple wavelengths and powers. This article will introduce what QSI Company is, why QSI laser diode is selected, and the qualification and specific purchase method of Longxingda Technology Co., Ltd. as the general agent of QSI in China (or Greater China).

What is QSI?

QSI specializes in the research and development, epitaxial (EPI), wafer manufacturing and packaging of semiconductor lasers, vertical cavity surface emitting lasers (VCSEL), micro-LEDs and RF devices. ([QSILaser][1])

Among laser diode products, QSI's product line covers red light and near infrared, including commonly used 635nm, 650nm, 780nm, 808nm and 905nm. Power ranges from low power to medium-high power to meet different application requirements.

Why choose QSI laser diode?

Several advantages of choosing QSI products;

1. Mature technology: QSI has complete process capability in epitaxial wafer, light refining package and other links.

2. Product variety: multiple wavelengths, multiple packaging forms and different power specifications, which can be adapted to many applications such as bar code scanning, ranging, industrial laser, medical instruments and so on.

3. Stability and consistency: According to the feedback from agents and the market, QSI's laser diodes have a good performance in terms of production consistency and optical performance stability. One of them is the model of "high stability and consistency" marked by Longxingda Technology.

QSI is the general agent of Longxingda Technology in China.

Longxingda Technology Co., Ltd. ("Longxingda" for short) is the general agent of QSI's laser diodes in China (Greater China). The following are the company's main information and service advantages.

Company qualifications and responsibilities

Founded in Shenzhen, Longxingda Technology is a company specializing in the agency and sales of photoelectric products, covering product research and development support, technical services, after-sales support and other links.

The core value of the company is "focusing on brand and serving with heart". If customers need QSI laser diode models with various wavelengths and power specifications, Longxingda can provide selection suggestions, technical data, samples and batch supply.

Longxingda has extensive coverage and good reputation in China market, and is a stable supplier of many industrial and scientific research projects.

Available model sample

Examples of QSI laser diode models represented by Longxingda include:

Model with infrared wavelength of 905nm and power of 10mW ("infrared laser diode with high stability and consistency of QSI in Korea")

Other optional wavelengths: 635nm, 650nm, 670nm, 780nm, 808nm, 830nm, etc. Different powers from several milliwatts to hundreds of milliwatts can be selected according to different applications.

How to buy QSI laser diode through Longxingda

The following is the general process and precautions for purchasing QSI laser diodes through Longxingda Technology:

You can reach official website through Longxing or call the specifications of wavelength, power and package type you need. Providing application scenarios helps the other party to recommend the appropriate model.

Obtain samples or quotations. The other party can provide sample tests or detailed quotations. If you buy in bulk, the price and delivery cycle are usually better.

Technical support Longxingda usually provides data such as technical parameter list, product stability and conformity test report for customers to design and verify.

Quality and certification, the total generation that keeps cooperation with QSI original factory can usually guarantee that the products are genuine and have a complete warranty; It is recommended to confirm whether you have a certificate of conformity, original factory label, etc.

If you are looking for a reliable and stable QSI laser diode, Longxingda Technology is a trustworthy channel. As the general agent of QSI in China, they can provide genuine products, samples, bulk supply and technical support. It is recommended TO make clear the wavelength, power and package type (such as TO package, lead type, modular type, etc.) you need before purchasing, and confirm the original information and certification of the products to avoid the problem of unclear channels or inconsistent quality.
