Understanding Line Laser Diode Modules

A line laser diode (LLD) is a type of light emitting diode (LED) that operates on a single line. Compared to other types of LID, an LLD only requires one set of power-wiring for its operation and maintenance. Because of this, it is often used as a part for medical equipment that requires minimal and long lasting adjustments. One can even adjust it to any position with just a single push of a button. For example, a laser pointer attached to a medical device that uses a single line will be at its optimal height and setting with just one press of a button.

An additional feature of the line laser diode is its use of a 5-volt supply voltage instead of a direct current (DC). This power supply voltage enables the diode to operate at a higher level than a typical laser diode. Since the voltage supplied by the supply voltage is in the range of one volt up to five volts, the system will operate at full output with a five volt current. On the other hand, if the supply voltage is too low, the device may function but its output will be much lower than required. With this feature, an LLD can be very useful in medical applications where there is a need for a higher level of output than a normal laser.

One feature of the laser diode module is its adjustable lens. The adjustable lens of an LID enables the user to adjust its focus from anywhere within the diode’s tube. This feature makes it possible to use the device on different types of media such as gel, water, and even plastic. With the appropriate lens and its appropriate setting, the device can adjust its output power to that of the source or target.

Another feature of an LID is its adjustable working distance. The working distance refers to the distance between the laser diode and the surrounding media. The longer the working distance between the source and the diode, the more powerful the laser output. To ensure that the laser diode is working properly, the working distance must always be adjusted to match that of the source or target. A typical laser diode module is designed to have a minimum and maximum working distance depending on the application and desired output power. The working distance is adjusted to the appropriate level by rotation of the target on the axis and also by increasing and decreasing the ribbon’s total length.

The last feature to look out for is the availability of different drive modes. The available drive modes are Continuous Cycling, Constant Cycling, Random Cycling, and Particle Cycling. The Continuous Cycling drive mode is the most commonly used in the LID. It produces the most output power because the diode does not change its state. The constant cycling mode changes its state while the output power is adjusted so that the cycle time remains consistent. The random Cycling, on the other hand produces the lowest output power because the diode does not change its state.

While purchasing any line laser diode modules, it is important that the output voltage and current are known. Since the modules are meant to function in tandem with one another, there is a need for compatibility among the different brands and models. For this purpose, there are manufacturers who produce their own line of compatible products. The best place to search for compatible laser diodes is the internet where there are manufacturers showcasing their products online.

The last factor to consider when buying a laser diodes is the lens. There are mainly three common types of LID lenses: low power, intermediate power and high power. High power lenses are suitable for general-use applications; however, they are not capable of producing high image quality. On the other hand, low power lenses produce good images; but they consume a lot of power.

To improve an already great product or service, the company must always address the needs of their customers in the most cost effective way. A line of LID lenses may look good on paper; however, the way it will work in real life is entirely different from a model on paper. Therefore, it is very important to choose a laser diode line based on its specifications, functionality and compatibility as well as its price.
