The Photron Fastcam Orion S40 high speed camera can image 31,250 fps at full resolution and 37,500 frames per second at 1,024 x 1,024 megapixel. Image resolution of 1 million pixels high-speed shooting performance that is approximately twice as fast as the FASTCAM NOVA S20 high speed camera.
Orion S40 brings together innovative CMOS image sensor technologies and extensive high-speed digital imaging expertise to provide a camera with the flexibility to be used in a wide variety of applications. FASTCAM Orion is a high-quality model that achieves ultra-low noise by using the latest sensor technology with a back-illuminated image sensor(BSI) and CDS function. CDS function (Correlated Double Sampling) is a function that takes the difference between the noise level and the luminance signal level of each pixel for each frame. Since it is possible to capture clear images with ultra-low noise, it is possible to perform measurements with high accuracy using image measurement methods such as PIV (Particle Image Velocimetry) and DIC (Digital Image Correlation).
As science and technology advances, there is an increasing need for more precise video analysis in the R&D departments of private companies and in cutting-edge R&D themes at universities and government agencies. Particularly in fields such as fluid analysis, material testing, and shock and vibration testing, technology that can capture minute changes and phenomena that could not be captured by conventional high-speed cameras with low noise and high frame rates is essential.
Target applications include:
- Offboard automotive safety testing
- Biomechanics
- Life sciences
- Defence and aerospace research
- Material sciences
- PIV (Particle Image Velocimetry)
- DIC (Digital Image Correlation)

Understanding the Main Features of Cavitar’s CAVILUX Smart and CAVILUX HF Pulsed Illumination Lasers
Wavelength and Spectral Characteristics
The wavelength of illumination plays a crucial role in machine vision systems. Selecting the correct wavelength enhances image contrast and reveals specific features that might otherwise remain invisible.
The CAVILUX's monochromatic light eliminates chromatic aberrations commonly found in white light systems. Moreover, unlike coherent laser sources that produce speckle patterns, CAVILUX's low-coherence design delivers clean, speckle-free illumination while maintaining the benefits of laser light.
Different wavelengths offer distinct advantages in machine vision applications:
- Infrared illumination (like CAVILUX's 810 nm option) diminishes color effects in monochrome images, enhancing contrast of colored objects and simplifying inspection.
- Visible red light (640 nm in CAVILUX) provides excellent contrast for many applications where visible illumination is preferred.
Ultimately, the monochromatic nature of laser illumination also allows for efficient filtering of thermal light, enabling clear visualization of extremely hot processes like welding, where traditional lighting is overwhelmed by the process's own emissions.
If visible light is necessary, then CAVILUX Smart 650nm and 300W CAVILUX HF 650nm is the standard products with visiable red illumination. The CAVILUX HF is equipped with a visible laser pointer beam (green light). Color cameras typically have an IR cut filter in front of the sensor which blocks 810 nm. Some cameras allow the removal of that filter and in this case CAVILUX 640nm and 810nm pulsed lasers can be used.
Fiber core diameter
CAVILUX Smart pulsed laser has a fiber core diameter of either 3mm or 5 mm, whereas CAVILUX HF pulse laser has a fiber core diameter of 1.5 mm. This means that CAVILUX HF has 4-11 times higher brightness than CAVILUX Smart. Higher brightness enables the illumination of a smaller area from a certain distance or, alternatively, the illumination of a certain area from a greater distance. CAVILUX Smart 200 W provides a higher brightness than CAVILUX Smart 400W if the illuminated area is smaller than 3 mm.
Motion Blur Reduction: 95% Improvement with Laser
Traditional lighting systems struggle with fast-moving objects, creating blurred images that lack precision. The CAVILUX laser system demonstrated a remarkable 95% reduction in motion blur compared to halogen illumination. This dramatic improvement stems from the laser's ability to generate extremely short pulses that effectively "freeze" motion regardless of camera shutter speed.
Unlike conventional lighting, where motion blur increases proportionally with object velocity, the CAVILUX system maintains image clarity at speeds that overwhelm traditional solutions. The laser pulses can be as brief as 50 nanoseconds, which is approximately 200 times shorter than the fastest exposure times achievable with most industrial cameras. Therefore, even when objects move at exceptional speeds, their positions remain fixed during the illumination period.
Minimum pulse duration
The minimum pulse duration for CAVILUX Smart enabling full output power is ~30 ns. CAVILUX Smart can create pulse durations up to 10 ns but then the output power is lower. The minimum pulse duration for CAVILUX HF at full power is ~100 ns and 50 ns at lower output power. A very short pulse may be needed for removing motion blur when a small and fast-moving object is studied at high magnification. CAVILUX Smart has shorter rise and fall times than CAVILUX HF. Therefore, Smart can generate extremely short pulses (below 100 ns) more accurately than CAVILUX HF.
The CAVILUX system's flexibility in pulse duration settings enabled optimization for different applications—shorter pulses for ultra-high-speed phenomena and slightly longer pulses for applications requiring greater illumination intensity. Indeed, the system demonstrated that in accordance with two-photon absorption principles, shorter pulses required significantly less average optical power to achieve equivalent visibility.
For real-time monitoring applications requiring continuous imaging, the laser's high maximum duty cycle supported frame rates up to several MHz for brief periods, outperforming traditional lighting solutions in both speed and clarity.
Maximum duty cycle
Due to the difference in duty cycles CAVILUX Smart laser is typically used together with machine vision cameras and CAVILUX HF laser with high speed cameras. CAVILUX Smart laser may also be compatible with certain ultra high speed cameras, depending on the application and camera with short record buffers.
As an example, if the object doesn’t emit thermal light and 100 ns pulses are sufficient for illuminating the object, CAVILUX Smart laser can provide optimal results up to 10 kHz, independent of the minimum exposure time of the camera.
However, if the object emits thermal light (e.g. arc welding), it is usually important that the laser pulse is of similar duration than the camera exposure time (and that the camera exposure time is properly synchronized with the laser pulse). In such a situation, having a camera of 1 µs minimum exposure time, CAVILUX Smart laser can provide optimal results up to 1 kHz (provided that the synchronization between the camera and the laser can be realized properly). Most likely acceptable results can be achieved also at somewhat higher frame rates (up to a few kHz), but the whole camera exposure time won’t be covered by laser illumination anymore (thus making the effects of thermal light stronger than in an ideal situation).
