Photron FASTCAM SA-Z high-speed camera
Photron FASTCAM SA-Z is a compact, mobile, autonomous black-and-white camera suitable for recording very fast and
short-period, transitional and/or stochastic processes. Available accessories are: image digitalizer and other
equipment for video recording, processing and analysing. The camera is widely applicable in research, equipment design,
parts/components and material testing.
Specification
- maximum image resolution 1024 × 1024 px at frame rate 20 000 fps
- maximum frame rate 2,100,000 fps at resolution 128 × 8 px
- data transfer by two gigabit Ethernet cables or direct storage on SD cards
- manual or electronic (TTL 5V) trigger in recording
- sophisticated options of synchronization and timing, programmable delay on selected input and output triggers, 100 ns resolution
- possibility to store the analogue signal in addition to video
- IDT LED lamp (130 W) for supplemental scene illumination
- set of lenses and filters enhance the recording quality
Typical applications
- primary information on flow features in fluid dynamics prior to application of optical measuring methods
- suitable also as the main experimental method for studying fluid flow fields
- air flow visualization in research related to room heating, ventilation and air-conditioning
- observation of air/gas discharge from air terminal devices and pipes, nozzle discharge, two-phase flow
- assessment of indoor environment of vehicles
- studies of flow around bodies, mixing of gas jets
- crash tests, fast motion tracking of objects, testing of firearms/ammunition/explosives
- research into biomechanics and biological processes
- evaluation of trajectories of machine mechanisms, robotic production lines, high-speed machining etc.
- research into combustion processes
