Request Infopiezosystem jena GmbHUsing a laser beam for cell stimulation within biological applications is a delicate science. An important requirement is to hold the beam onto the cell but due to external vibrations and thermal effects, this can be a difficult achievement. Operating in response to signals received from a system consisting of two piezo-driven mirrors and two position-sensitive, four-quadrant diodes, piezosystem jena’s mirror tipping and tilting piezostage PKS1 stabilizes laser positioning on the cell. This piezostage adjusts the direction of the mirror in milliseconds with a frequency...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueZinc Selenide OpticsHigh-quality zinc selenide (ZnSe) lenses, output couplers, and mirrors from Laser Research Optics are optimized at 1.06 μm for medical laser OEMs. The devices are manufactured to...Photonics.com 8/31/2022Broadband and Wide-angle Laser Line MirrorsBroadband and Wide-angle Laser Line Mirrors from Knight Optical Ltd. feature an Ion Beam Sputtered (IBS) coating to meet the demanding requirements sought by laser system manufacturers. ...Promoted Content June 2023 IssueNanopositioning for High-Res MicroscopyPI's new Fast Focus Stages and Multi-Axis Piezo Flexure Scanners for Microscopy are designed to improve the performance of high-resolution microscopy.
