Fundamentals of Beam Profilers
: Benefits of Implementation and Use Cases
When working with lasers or LED light sources, the use of a beam profiler is essential.
Employing a beam profiler offers numerous advantages, including stable quality assessment in the quality control of laser oscillators and optical systems, the prevention of potential issues before they occur, and various other operational benefits.
Calculating Maximum Laser Power Density
and Selecting the Appropriate Attenuator Set
A key feature of Kokyo’s beam profilers is their capability to handle large-diameters and high-power beams. However, exposing the image sensor to excessively strong light can still lead to sensor failure.
This document explains how to calculate the maximum allowable laser power density and pulse energy density to ensure safe operation and prevent image sensor damage. It also provides an overview of the attenuator sets used to reduce beam power.
Calculating the Minimum Measurable Beam Diameter
and an Overview of Micro-Beam Diameter Measurement Optics
When using a beam profiler, accurate measurement becomes difficult if the beam diameter being measured falls below the profiler’s minimum measurable beam size. Therefore, calculating and confirming the minimum measurable beam diameter of the product is essential.
This document explains the mechanism behind determining the minimum beam diameter specified for each product by outlining the calculation method.
It also provides an overview of micro-beam optical setups for measuring laser beams that are smaller than the profiler’s minimum measurable beam diameter.
For High-Power Green Lasers & Fiber Lasers Beam Profiler Introduction
Green lasers and fiber lasers are widely used for laser processing applications such as metal cutting, welding, marking, and microfabrication. But how should one perform beam profiling for these high-power lasers?
This document explains the relationship between wavelength and processing performance in laser machining, and introduces beam profiler products designed for high-power green lasers and high-power fiber lasers.
Introduction to
Deep Ultraviolet Beam Profilers
Ultraviolet (UV) light refers to wavelengths below 400 nm. UV light is further categorized into four major groups.
This document explains the characteristics of each UV category—including deep ultraviolet (DUV)—as well as the applications of DUV light. It also introduces beam profiler products capable of detecting and measuring UV light.
LBP Series Beam Profiler Options for Large-Diameter and High-Power Applications
Kokyo’s LBP-B Series beam profilers are the world’s leading optical instruments for measuring exceptionally large beams. They can be used even in applications that are difficult for conventional beam profilers.
This document also introduces optional products for the LBP-B Series, including an attenuator option that supports total incident power of up to 150 W, as well as an option that enables observation with up to 1,000 times higher sensitivity.
