Fluid Imaging Technologies has patented a new system capable of imaging birefringent particles.
The technology features two cross-polarising filters to automatically detect the presence of anisotropic particles and microorganisms.
The system works by allowing light to pass through to the camera for imaging only after passing through the birefringent particle and through both polarisation analysers.
The new advance effectively isolates birefringent targets of interest for analysis while blocking particles and microorganisms not exhibiting birefringence from being imaged.
According to the company, it is ideal for the detection, monitoring and analysis of food ingredients, plastic resin, fibers, abrasives and crystals as well as for invasive mussel veligers such as the zebra and quagga mussels.
For versatility, the patented imaging technology may be switched off in seconds to permit automated detection and imaging of both birefringent and non-birefringent particles and microorganisms at the same time.
The new advance may also be retrofit on FlowCAM units in the field.
Standard portable FlowCAM’s features include:
- A compact, transportable case
- Operation on 120/240VAC or 12V DC (car battery or accessory plug)
- Four magnifications (2X, 4X, 10X and 20X) available to accommodate broad range of sample particle sizes (2µm to 2mm)
- VisualSpreadsheets software for data capture and analysis
