KEY FEATURES
Our longitudinal Pockels Cells are often used in polarimetry on imaging light beams and in the chopping of polarized beams. They consist of Z-cut KD*P crystals between protective windows that have transparent indium-tin oxide electrodes applied to their interior faces. The electrodes produce a uniform electric field normal to the optical faces and permit use of a thin (approximately 3 mm) KD*P crystal.
As shown on the response graph, the electric field creates a positive or negative retardance value depending on the instantaneous field direction.
The thin crystal additionally makes these cells suitable for use in non-collimated imaging light beams slower than f/20. Meadowlark specializes in clear apertures up to 40 mm. These devices are useful as variable retarders in applications requiring very fast switching.
Due to the wide variation in customer applications, Meadowlark is unable to provide a turn-key high voltage driver, but is pleased to help identify the critical voltage/current requirements.

Cambridge, MA. From sculptedlight.org: Sculpted Light in the Brain is a recurring conference (founded in 2017) aimed at fostering collaborations between neuroscientists, computer scientists, optics researchers, and other scientists who share the common interest of using and developing novel technologies to observe and control neural activity in the awake, behaving brain. “Sculpted Light” refers to a broad class of methods where light is shaped to probe neural function. This meeting aims to promote future collaboration opportunities by gathering established scientists and the next generation of researchers from these fields to discuss future technologies that will enable real-time optical communication with the living brain.
