A 375nm/405nm UV fiber-coupled laser is used for LDI (Laser Direct Imaging) by precisely transferring a digital image directly onto a photosensitive material, such as a PCB. The fiber coupling directs the UV light to a scanner or printhead, where it is rapidly focused and moved across the substrate, creating patterns without the need for physical masks. The specific wavelength (375nm or 405nm) is chosen for its effective absorption by the imaging materials used in LDI applications.

Lasers are basically classified into 5 types based on their active medium. They are

Semiconductor laser

Liquid-state laser

Gaseous-state laser

Solid-state laser

Metal Vapour laser

We will discuss some of these types in the upcoming parts of this article.

From healthcare gadgets to tiny electronics, laser tech has reshaped countless fields. Among the many kinds of lasers we have today, violet lasers—which give off light around 405 nanometers—are special because of their unique color and precision. That eye-catching purple-blue glow isn’t just for loo

Lasers are commonly used in most trades, particularly construction, installations, and surveying. They are used to project vertical, horizontal (and sometimes both) lines in either green or red to acquire fast and accurate measurements over a long distance.
But, what is the difference between the colours red and green? Is there any practical advantage to using one over the other? The fact is, there is absolutely no difference when it comes to accuracy. Both are (pun intended) laser-accurate. Ultimately, the key differentiators between the two are price, brightness, visibility, and battery life.

Laser modules are revolutionizing industries worldwide. From healthcare to telecommunications, their applications are vast and growing. These compact devices combine advanced components to deliver precise, focused light.In this article, we’ll explore what laser modules are, how they work,

Both semiconductor lasers and CO2 lasers create concentrated beams of light, usually used for cutting away material, but they work in drastically different ways. They generate power through two different mechanisms, and each type of laser can come in diverse subtypes and configurations. Still, both processes start with reliable electrical power delivered from a sophisticated power supply.
