635nm 200mW Red Laser For Optogenetics

      Optogenetics is a neuromodulation technique employed in neuroscience that uses a combination of techniques from  optics  and genetics to control and monitor the activities of individual neurons in  living tissue to precisely measure the effects of those manipulations in real-time.   Changchun New Industries  (CNI) offers fiber-coupled laser as the stimulation light source for the optogenetics research, which provides a controlled wavelength and pulsing modulation option, and having fiber optics attached to the laser module allows for a convenient method of delivering the light to a selected target site. CNI's blue, yellow, and green laser modules are currently being used in many leading laboratories, also we can provide the below wavelengths with options such as enhanced power stability, low noise amplitude, power adjustment and controllable pulse frequency/duty cycle.       Features   CNI provided high reliability lasers All the necessary accessories can be provided Easy to install and maintain Customized solution can be provided upon request   SPECIFICATIONS:
