RWD is going to debut the third-generation Laser Speckle Contrast Imaging System- RFLSI-ZW. The new version inherits the advanced technicals of RFLSI Ⅲ, offering powerful performance and enhanced functionality for an optimized experience to speed up your research, and maintaining its continuous influence and supporting role in the field of microcirculation research.
The eye-catching upgrades of the third-generation RFLSI-ZW include:
The RFLSI ZW adopts a new global shutter CMOS sensor with higher quantum efficiency, which enables significantly less noise and sharpens images even in a short exposure time. With a global shutter camera featuring higher data transmission speed, RFLSI ZW can acquire images at a speed 3 times higher than that of the previous version in high-resolution mode.
The maximum imaging size of the RFLSI ZW is 225mm*300mm, which is nearly 8 times wider than that of the RFLSI Ⅲ. The imaged object range is extended from small animals to large animals and parts of the human body. The scope of application got further expanded.
The RFLSI ZW laser speckle blood flow imaging system has further improved its imaging algorithm. Compared with that of the RFLSI Ⅲ, the number of image syntheses have been increased by 5 times in the spatial algorithm mode and 24 times in the temporal algorithm mode, getting higher resolution with more amplified details.
The device is provided with a BNC extended interface to communicate with external devices, such as electrophysiology equipment, stimulator, syringe pump, optogenetic equipment, etc. Based on the software control protocol, the working sequence, interval, frequency and other parameters of the equipment can be customized to meet the diversified experimental requirements.
Along with standard calibrators and the calibration program, the product can be regularly self-calibrated to keep itself in the best working condition, enabling the perfusion parameters and blood flow maps obtained at different periods could be compared.
This new-generation laser speckle blood flow imaging system RFLSI ZW has been upgraded in terms of safety. It meets the Class1-IEC 60825-1:2014 standard and is secure to use, further ensuring the safety of experimenters.
