Why SWIR is Beneficial for Laser Applications

Jun 22, 2023 | News

In the world of laser technology, the use of Shortwave Infrared (SWIR) has proven to be immensely beneficial. SWIR refers to the portion of the electromagnetic spectrum that spans from 900nm to 1700nm. It lies between the visible and long-wave infrared regions, showcasing distinctive properties that set it apart from other types of light. Unlike visible light, SWIR is invisible to the human eye, but it can be detected by specialized cameras and sensors. This technology offers a range of unique characteristics that have revolutionized laser applications and opened up new possibilities in various industries. In this blog post, we will explore the advantages of SWIR for laser applications.

Advantages of SWIR for Laser Applications

In comparison to other types of light used in laser applications, SWIR holds several distinct advantages. These advantages contribute to improved accuracy, precision, and efficiency in laser systems, especially in outdoor applications where visibility may be limited.

Complementary Capabilities of Thermal Cameras

When used together with thermal cameras, SWIR cameras provide complementary capabilities. They excel in low-light conditions while offering the ability to capture images during daylight as well. This versatility ensures consistent imaging performance across different lighting scenarios.

High-Resolution Imaging

SWIR cameras deliver high-resolution imaging, capturing tiny details with outstanding clarity. This attribute is valuable in scientific and industrial applications, where precise analysis and visualization are paramount. NIT’s state-of-the-art SWIR cameras offer excellent imaging, with some up to 2k resolution.

High Sensitivity to Invisible Light

SWIR cameras possess high sensitivity to invisible light, enabling the detection and analysis of light wavelengths beyond the visible spectrum. This feature makes SWIR cameras invaluable in applications such as military imaging and semiconductor inspection.

Illumination-Free Operation

One of the primary benefits of SWIR cameras is their ability to operate without the need for additional illumination. This simplifies the setup and ensures efficient imaging in various conditions, enabling SWIR cameras to be used in cost-effective and practical laser applications.

Unmatched Visibility Through Obstacles

SWIR cameras offer unparalleled visibility through obstacles like fog, smoke, and materials such as glass. This unique characteristic allows for high-quality imaging in challenging conditions, making SWIR ideal for applications that demand reliable and clear visualization.

New Imaging Technologies and SWIR Products

Shortwave Infrared (SWIR) has emerged as a powerful ally for laser applications, revolutionizing the way lasers are used across various industries. With its ability to penetrate obstacles, capture images through glass, differentiate objects, provide depth of penetration, identify beacons and lasers, and accurately assess power distribution, SWIR offers significant advantages over other types of light. Its utilization enhances the accuracy, precision, and efficiency of laser systems, paving the way for advancements in laser material processing, spectroscopy, and other fields. 

Within the realm of SWIR cameras, New Imaging Technologies (NIT) is a prominent player that offers cutting-edge solutions for laser applications. Our SWIR cameras are manufactured with state-of-the-art InGaAs material in-house to offer innovative and cost-effective solutions in laser applications and more.
