Holographic Photostimulation

Non-mechanical shaping and focusing of light extend what’s possible with calcium imaging and optogenetics techniques
The emergence of calcium imaging and optogenetics has provided neuroscientists with powerful tools to optically interrogate brain function. Our SLMs are designed to provide >500 Hz frame rate of accurate, efficient, phase masks in the near infrared with microsecond-scale trigger latencies to ensure the light arrives where and when you need it. And with the large, actively cooled, 30 mm x 30 mm array size of our 1536 x 1536 pixel SLM, you can deliver the laser powers required to stimulate larger populations of neurons over larger volumes.
In addition to SLMs, BNS switchable polarization lenses enable fast, inertialess remote focusing of microscope objectives with apertures and speeds unattainable with liquid lenses. Remote focusing with liquid crystal polarization lenses eliminates the ringing, settling, and hysteresis common in many remote focusing techniques while enabling sub-millisecond refocusing to up to tens of different focal planes.
As researchers ourselves, we take the time to understand what you are trying to accomplish and can adapt the technologies to meet your needs.
