LaVision launches the next generation of PIV cameras – the Imager CX3p Camera Series!

All the advantages of the Imager CX3 camera series, which was successfully introduced last year, were the basis for this further development.

The small and compact cameras of the Imager CX3 camera series, which are equipped with the innovative back-illuminated technology that enables incredible sensitivity and very low noise, have already been a resounding sales success. The small pixels enable very small fields of view for a given lens, and the hardware binning guarantees exceptional frame rates and therefore increased flexibility when using these cameras.

LaVision is now launching the unique Imager CX3p camera series, which is equipped with an integrated Scheimpflug mount for adjusting the angle between camera and lens (Scheimpflug angle) for C-mount and F-mount lenses.This ensures quick and easy alignment of the viewing direction, Scheimpflug angle and sensor orientation.

The integrated Scheimpflug mount offers three independent setting options for tilt, rotation and sensor orientation. All settings are supported by an intuitive DaVis software tool resulting in very quick and easy Scheimpflug adjustment.

Here you can watch our video, showing the easy handling of this camera with all its Scheimpflug settings as well as the adjustment of the Scheimpflug mount supported by our user-friendly DaVis software tool.

Detonation Analysis by using the Solid-State-Streak-Camera S3C-1

Visualisation of Detonation Front Curvature with Nanosecond Temporal Resolution

The chemical reaction inside a homogeneous explosive agent can be initiated at a small spot and will then propagate spherically from this spot. The propagation can be observed as optical emission at the interface between the explosive and the air. Measurement along only one line is sufficient, but must be recorded with high temporal resolution in the nanosecond range to capture fast reactions. The spherical propagation leads to the curvature of the detonation front. The emission is expected to start in the center of the line and then propagate symmetrically along the line toward the edges. The analysis of this curvature allows the determination of the dynamic processes inside the explosive.

Instead of using a conventional tube-based streak camera, the solid state streak camera S3C-1 is used. The propagation of the optical emission is completed within 2 µs and the S3C-1 allows to capture this with 10 ns temporal resolution. A post trigger feature of the S3C-1 is used to capture the emission without being affected by the strong jitter of the detonator. An application note describes the setup and experimental details. It is available on request.

SIM Cameras now optimised for Ultra High-Speed Multispectral Imaging

Specialised Imaging’s latest version of the SIM ultra high-speed framing camera is making multispectral imaging simpler with the option of user interchangeable filters.

Specialised Imaging is continually evolving its products to meet new and challenging requirements. In response to increased requests, the latest evolution in the SIM cameras makes it simple to interchange standard size filters for multispectral imaging – capturing different wavelengths on each channel. Multispectral imaging was possible on previous SIM models, but the new SIM design simplifies the user exchange of filters for all channels.

This evolutionary step in the SIM camera design was driven by requests in the field of energetic materials research. Using filters in a camera allows researchers to obtain spectral, spatial and temporal information for comparing different energetic materials by focussing on the different spectral signatures. The nature of energetic materials mean you need an ultra-fast, light sensitive camera that can respond to a broad range of wavelength to provide a flexible solution for this and other applications.

Users can now easily interchange filters on all eight channels. The SIMX camera captures one high resolution image per channel, offering the potential to capture 8 mono/filtered images and potentially two monochrome and two full colour images using red, green & blue filters. Similarly, the SIMD camera captures two images on each of its eight channels, offering the capacity to capture 16 mono/filtered images, or four mono and four full colour images. By responding to our customer input and requests, this capability expansion of the SIM cameras continues to support new and novel applications for the advancement of research.
