The LDF100C is a laser Doppler tissue perfusion monitor for measuring micro-vascular blood flow in tissue. The LDF100C amplifier delivers a low power beam of laser light down an optical fiber to the tissue being studied; typically, the volume of tissue sampled by the light is in the order of 1mm3. The LDF100C amplifier analyzes the Doppler shift created by moving red blood cells and outputs a channel indicating blood flow expressed in Blood Perfusion Units (BPU). On a second channel the LDF100C simultaneously outputs the tissue remittance (Backscatter) from 0 to 100%. Up to four LDF100C amplifiers can be used with a single MP System. See the extensive range of TSD140 series laser Doppler flow probes in the transducer section.
If probes are shipped with the LDF100C, they are factory-calibrated to the module (except Disposable probes). Otherwise, probes are shipped uncalibrated. The LDF100C requires an appropriate Blood Perfusion Unit standard (LDFCAL) when (re)calibrating new or existing probes.
IMPORTANT- The LDFCAL solution has a 3-month lifetime (from creation, not from first use), so it's best to order it only when required.
The LDFCAL has a limited shelf life and should be purchased close to planned usage.
