Fundamentals of Beam Positioning
BEAM-POSITION MEASUREMENT
A unique characteristic of a laser beam is that it propagates through space as a perfect line
from point A to point B. Based on this capability, many straightness and positioning devices are available. However, although traveling from A to B is a prefect line, changes in emitted position as a function of time, age, and atmospheric conditions are a known phenomenon. In most cases, this movement is only a fraction of a beam’s diameter, but in a long-path this movement can cause problems.
Fundamentals of Beam Alignment
ELECTRONIC AUTOCOLLIMATOR FUNDAMENTALS
The electronic autocollimator is a high precision angle measurement instrument capable of measuring angular deviations with accuracy down to fractions of an arc-second.
It can be used in numerous applications in a variety of areas. Some examples include: perform a machine alignment, measurement of slide ways, precision machines, accurate optical assemblies, alignment of optical setups and more.
Fundamentals of Laser Beam Measurements
INTRODUCTION TO BEAM PROFILING AND BEAM MEASUREMENT
A laser propagating through space has a different width and spatial intensity distribution along its propagation path continuously changing as a function of its laser cavity, divergence, interaction with optical elements and electronics driver characteristics. Beam profile intensity distribution is an important parameter that indicates how a laser beam will behave in an application and will dictate the overall system performance in a specific setup.
Fundamentals of M2 Beam Propagation
M2 MEASUREMEMNT
The beam propagation factor is a common single parameter that characterizes the whole beam as it propagates through space. According to ISO standard 11146, this parameter could be defined by several measurement techniques based on beam profiling along several points of the propagating beam. The standard defines several measurement techniques, all of which are based on beam profiling measurements using devices such as cameras, knife-edge and slits.
Fundamentals of Measuring LAM Machines
INTRODUCTION
Recently, a new emerging technology of metal 3-D printing or LAM (Laser Additive Manufacturing) is recognized as the new advantageous process for metal parts manufacturing. For this application, lasers play a significant role since they can focus large amounts of energy on a wide range of material powders, fusing the particles into 3-D parts. Important laser and machine optical parameters need to be analyzed in order to insure repeatable and excellent results. The LAM process is based on a layer-by-layer construction, wherein each layer is selectively fused on top of each other until the part is a finished product
Application Note - Alignment of Articulated Arms
The AlignMeter can serve as an accurate and simple device for the alignment routine of robotic arms or articulated arms.
The instrument can measure both the positional and angular beam runout of the articulated
arms used as part of the laser beam delivery system on several of medical laser products.
Applications for Autofocusing Autocolllimator
Our Autofocusing Autocollimator is characterized by its capability to focus along its propagation axis at different distances via a motorized system which is controlled by a software specially adapted and activated through a PC
