Why Use a Flat Top Beam Shaper?
A beam shaper top hat is a diffractive optical element (DOE) that alters the phase of an incoming Gaussian beam into a flat top-shaped energy distribution. This article will discuss the beam shaper top hat’s qualities and when it is advised to use such a device. Introduction to beam shaping optics Nowadays, the advancements in … Continue reading

Femtosecond Lasers for Medical and Jewelry Applications
The medical field uses high-contrast marking, sometimes called black marking, to mark medical tools. White marking enhances the visible quality of watches and jewelry products. It is possible to apply deep engraving, high contrast marking, medical instrument marking, hidden marking, counterfeit marking on glass, plastic, metals, and ceramics. The femtosecond lasers PHAROS and CARBIDE from Light Conversion are the … Continue reading
Laser Display Debonding without Cylindrical Optics
Laser debonding requires the formation of a thin long line, typically achieved by using large, complex, and expensive cylindrical optics. This article presents an alternative approach utilizing a single diffractive optical element (DOE) and a standard F-theta lens. Background: Laser UV Debonding In many flat panel processes, the active screen layer is often extremely thin, … Continue reading
Filters for Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR) is a technique to make multiple copies of a short sequence of target DNA, exponentially amplifying it. DNA must be amplified so that there is enough material to reliably detect and identify it with a high degree of confidence. The multitude of PCR applications include infectious disease diagnosis. If the target … Continue reading
