MappingLab Ltd offers standard OMS-PCIE-1001, OMS-PCIE-1002 and OMS-PCIE-2002 systems as well as customized systems. Dual signal optical mapping systems are suitable for simultaneous recording of cardiac membrane potential and calcium imaging. Our latest optical mapping system is equipped with back-illuminated scientific CMOS cameras with 95% quantum efficiency (QE) and pixel size from 6.5 μm x 6.5 μm to 11 μm x 11 μm. It provides high-speed, low-noise acquisition with a dynamic range of up to 50,000:1 (94 dB). The optical axis can be either vertical or horizontal. There are various I/O connectors to help researchers set up the communication system. An 8-channel TTL controller is designed to synchronize devices such as camera, LED light controller, stimulator, ECG, MAP, pressure and temperature probes with the optical mapping system. OMapRecord/Scope is an advanced data acquisition and analysis software with a user-friendly intuitive interface and highly efficient data management.
