LD Collimators & Diffractive Optics: Pattern-Generator
Diffractive Optical Element (DOE)
Description:
LD Collimators & Diffractive Optics: Beam-shaping-Optics
Diffractive beam shaping optics offer significant advantages, including precise control over the beam profile and the ability to generate a variety of shapes from a single optical element. They are also compact and lightweight, making them suitable for integration into small optical systems.
LD Collimators & Diffractive Optics: Pattern-Generator
A diffractive pattern generator leverages the principles of diffraction and interference using specially designed optical elements to create and project specific light patterns for a wide range of scientific, industrial, and commercial applications.
