Power Affects The Quality of The Laser Beam

How to choose a laser pointer

A laser pointer is a tool that uses a laser as an indicator. The length that can be indicated is relatively long. It can replace pointers and other pointing tools. It can also be used for playing slides such as ppt for instructions. You can use red, green and blue laser pointers.

Using a laser pointer, the light spot can be seen tens of meters away, so the laser pointer is often used as an indicator. Most current laser pointers are red, green and blue are relatively few and expensive. The red laser pointer is easier to make, with a wavelength of about 600 nanometers, and has mature technology and mature semiconductor process materials. The wavelength of the green laser is about 530nm. At present, the semiconductor laser technology in this band is not very mature, so the green laser pointer is expensive and has low power.

In general, the difference is the process, power (brightness), and color. As for blue, there should be finished products, but it is definitely not cheap, not to mention yellow ones. These are closely related to the development of materials. Without the development of materials to that extent, there will be no blue and green lasers.

How to choose a laser pointer, LD (bulb) quality, lens quality, laser crystal quality, laser pointer power affect the quality of the laser beam, should pay attention to the following points when selecting:

1. Observe the light spot carefully in a dark place. If there is obvious flooding around the laser spot, it means the lens is not qualified;

2. Observe whether the light spot is a perfect solid dot;

3. Carefully observe whether there will be a problem of light and dark when the laser is emitted. If so, it indicates that the LD has a problem.

4. If it is a laser pen with lower power (below 20 milliwatts), you need to observe whether the brightness when the laser is just emitted will become darker and brighter again. If so, it means that there is a problem with the laser pen's circuit or LD.

Analysis of the Function of Laser Fine Tuning Technology

Laser trimming is widely used in the electronics industry at present. 200mw laser pointer fine-tuning of resistors and capacitors makes it extremely small in thermal impact on the adjacent components when processing, and does not produce pollution. It is easy to be computer-controlled and has the advantages of fast speed, high efficiency and continuous monitoring and other advantages, compared with conventional fine-tuning method, but also has high precision, good reproducibility and resistance does not change over time characteristics.

Laser trimming is widely used to fine tune the parameters of thick, thin film components and circuits, including resistors, capacitors, quartz resonators, parameter tuning of monolithic filters, hybrid integrated circuit amplifiers, voltage dividers, current stabilizers, digital simulations and simulations Digital converters, high frequency oscillators, operational amplifiers, quartz crystal devices (including oscillators, filters), and fine tuning of semiconductor integrated circuits, eliminating the limitations that affect the accuracy of multiple integrated circuits.
Because the laser beam can be precisely oriented, positioned within the minimum size area, and combined with a small thermal area of action in the specified form, precision thin-film elements can be fine-tuned because there is no intermediate (chemical) process in the process and can be performed in the atmosphere In the processing, so real-time test results, and 50mw laser pointer processing process to achieve automation, with high precision, process is simple and efficient features.
The sensor is a kind of detection device that can sense the information to be measured and transform the sensed information into electrical signals or other desired forms of information output according to certain rules to meet the requirements of information transmission, processing, storage and display , record and control requirements.
Sensor features include: miniaturization, digital, intelligent, multi-functional, systematic, networked. It is to achieve automatic detection and automatic control of the most important part. The existence and development of sensors, so that the object has a sense of touch, taste and smell and other sensory, so that objects slowly become alive again. Usually according to their basic perception function is divided into ten categories of thermal components, photosensitive components, gas sensors, force sensors, magnetic sensors, humidity sensors, acoustic sensors, radiation sensitive components, color sensors and taste sensitive components.
With the development of science and technology, sensor applications are also more and more widely, but with the resistance of the sensor components resistance accuracy can not be effectively controlled, many manufacturers choose to manually adjust the resistance, so that not only the accuracy Less than the guarantee, and the efficiency is still very low; a new type of 500mw laser pointer resistance device to solve this problem, the successful application of laser resistance in the sensor industry, to solve the problem of low efficiency, low accuracy, for the majority of production manufacturers save costs.
