Understanding Detectors With Thermoelectric Coolers

In order to optimize a detector for enhanced performance levels within their designated applications, it is important to understand the heatsinking of the package. A detector’s thermal resistance is minimized by the proper heat sink selection and mounting by using a thermal interface material.

Temperature Measurement Of Power MOSFETs Using FLIR Thermal Cameras

From individual component temperature measurement to thermal dynamics across a PCB, camera-based thermal imaging provides a cost-effective, accurate, and versatile solution.

How Does QPSI Technology Perform Against Vibration?

Vibrations can present challenges during phase-shifting laser interferometer measurements. Today, interferometers can measure with nanometer-levels of precision. In return, they can be susceptible to errors if used in loud or dynamic manufacturing environments where significant vibration is present.

Using IR Zoom Lenses For Long-Range Security And Surveillance Applications

Long-range IR imaging plays an important role in monitoring, tracking, and targeting within security and surveillance markets. Long-range IR cameras must be equipped with high-performance IR lenses that can effectively capture the emitted IR radiation and focus it onto a detector array.

Industry Insights
Understanding Focal Length And Field Of View

A fixed focal length lens, also known as a conventional or entocentric lens, is a lens with a fixed angular field of view (AFOV). By focusing the lens for different working distances (WDs), different sizes of fields of view (FOV) can be obtained, though the viewing angle is constant.

Gobi+, A Real Thermographic Sensor System

Xenics' Gobi+ camera has been demonstrated to be a good solution for temperature monitoring with its thermography capabilities. In addition to allowing temperature inspection and fire prevention in an industrial environment, it is also helpful in process monitoring.

Understanding High-Performance SWIR Imaging Cameras

The use of imaging systems to capture long wavelength photons continues to increase in diverse application areas. This white paper discusses the performance of InGaAs detector arrays with sensitivities in the VIS-SWIR region.

What Are Thin-Film Optical Filters?

Thin-film optical filters are made by depositing alternating thin layers of materials with special optical properties onto a substrate, such as optical-grade glass. As light makes its way through the optical filter, its direction changes as it passes from one layer to the next, resulting in internal interference.

Measuring High-Power Lasers With Low-Power Detectors: A Cost-Effective Solution
 

In industrial fiber laser applications like welding and soldering, it is rarely useful to measure the power of a laser beam before the end of the line since problems can occur after the point of measurement, at almost any point along the path that the light follows before it reaches the processed material.

Differential Pyroelectric Detectors

Laser Components offers the LD21xx series of differential pyroelectric detectors with crystal generating positive and negative charge carriers amplified separately on opposing sides. Due to the separate amplification, the signals add up linearly. The noise components only add up statistically, therefore creating a net gain in the signal-to-noise ratio.
