Optical Encoder Focus Axes for Precision Lens Positioning

Precise lens positioning in automated microscopy comes down to how accurately the focus axis can report and correct its own position, which is exactly what an optical encoder is built to deliver. WEISS's customer-specific focus axis solution pairs an optical encoder with pneumatic weight compensation, already proven in live automated microscopy applications requiring high-precision lens focusing. For manufacturers specifying focus systems for demanding microscopy applications, optical encoder feedback gives the closed-loop accuracy needed to hit focus reliably, cycle after cycle, without manual readjustment.
