The image on the left shows significant interference fringing without the design improvements featured in SWIR Vision Systems laser camera series. On the right, the same laser is imaged with this unique design feature and the fringes are eliminated.

SWIR Vision Systems is dedicated to supporting laser beam profiling applications, driving the next wave of laser innovation. Our Acuros CQD SWIR sensors are tailored to meet the unique demands of laser imaging, ensuring accurate and reliable characterization of laser beams. With our innovative technology, we empower researchers and engineers to unlock new possibilities and push the boundaries of laser-driven advancements.

We manufacture the world’s highest resolution SWIR image sensor available in a full HD 2.1MP format and with an active area diagonal of 33mm. This high resolution, large format sensor is also equipped with a spectral range spanning from UV out to beyond 2um and a wide dynamic range of 70dB maximizing your laser measurement detail. Finally, with innovative design features that minimize standoff distance to the active area while at the same time minimizing the potential for unwanted fringing artifacts across all wavelengths, SWIR Vision Systems cameras are the ideal choice for laser-based applications.

Given the diverse types of laser beams, spatial distributions, and their evolution as they propagate in free space and through optical elements, measurement of the beam profile is critical to quantify the irradiance at the point of the application. Monitoring the beam profile can also identify laser beam anomalies.

Cameras use a two-dimensional array of square or rectangular pixels as the imaging device. The intensity distribution of a laser or light source is recorded pixel by pixel and displayed as either a topographic or three-dimensional contour plot. The chief advantage of such profilers is that they can detect and display any structure that may exist on the profile and can be used with both continuous wave (CW) and pulsed lasers.

Laser Beam Profiling:

Laser beam profiling seeks to characterize various figures of merit including:
– Beam width
– Beam shape
– Energy uniformity
– Beam quality
– Beam divergence

You can visualize your beam like never before with the Acuros 1920L SWIR Camera. The significant advantage that a camera has over other methods of beam profiling like knife edge, pinhole, and slit profilers is that you get real-time measurements and views of your laser in action. SWIR sensors facilitate both near field and far field profiling applications and are specially designed to reduce laser-induced fringing effects.

Whether you are investigating SWIR cameras for benchtop laser profiling or highly automated industrial laser inspection, SWIR Vision Systems Acuros cameras are ideally suited to meet your laser profiling demands. With high pixel density, and large format arrays, all delivered at the lowest cost per megapixel, the family of Acuros CQD SWIR and e-SWIR cameras meet the challenges of the shortwave infrared optics and optical systems market.

Laser Beam Profiling Applications

Optics Alignment in Open Space Telecommunications Infrastructure

Free-space optical communication systems continue to grow in importance and demand improved performance. These systems must operate under extreme conditions to achieve the highest levels of reliability, speed, and reliability. Our SWIR area scan cameras allow for in-situ alignment, environmental wavefront testing, and metrological inspection – thus providing a high-precision optical metrology solution for your measurements toolkit.

Fiber Optic Alignment Systems in High-Tech and Product Manufacturing Factory Systems

For optimal alignment of fibers, lasers and optical components as part of the product production process, it is necessary to have a high degree of accuracy. Due to the small diameter and curvature of optical fibers, the alignment process is very complex and varies with many factors, including the gripping position of the pigtail and the curvature of the fiber tip. Consequently, the lack of standardization in the alignment process can be challenging. SWIR laser sensors can help improve the alignment process through high-precision beam measurement.

Laser Sensors as a Tool in Scientific Research Across Numerous Academic Fields, from Chemistry to Geo-Environmental Studies

Laser beam inspection has a wide array of applications across scientific fields. When precise measurement is needed through less than optimal visual conditions, SWIR cameras and sensors can pick up where conventional equipment leaves off – whether in the laboratory or out in the field.

Medical Optics Systems as a Part of Diagnosis or Treatment Protocols

Medical optical imaging is a great way to reduce patient exposure to harmful radiation. Unlike x-rays, optical imaging uses non-ionizing ultraviolet and infrared light. Because this type of imaging is safer, it is often used for repeated procedures to monitor the results of treatments and diseases. Optical imaging is particularly useful for measuring multiple properties of soft tissue, such as density, and can provide early markers of abnormal organ function.
