Choosing between Sequential Field Imaging (SFI) and TDI line scanning for fluorescence microscopy is a system-level tradeoff — not just a sensor decision. Our SFI vs. TDI Imaging Throughput Calculator helps engineers compare throughput across area sensor, line scan, and TDI-CCD approaches using real imaging parameters and motion conditions. It highlights: ✅ Throughput comparisons based on sample area, sensor format, magnification, pixel size, move time, line rate, and integration time ✅ How move-and-settle time affects SFI performance ✅ Why line scan can be difficult to implement in fluorescence microscopy ✅ Where TDI can improve throughput, and where SFI still outperforms it ✅ System-level considerations, including illumination, retrace, and detector performance To download the calculator below, open the document in full-screen mode by clicking it or the "expand" icon.

Our annual Summer BBQ was another great opportunity to step away from the day-to-day to enjoy great food and friendly competition, and to celebrate the incredible people who make Dover Motion so special. From cornhole and shuffleboard to paddleball and pool, there was no shortage of laughs and team spirit! We also took time to recognize an incredible milestone, celebrating Fred Rodriguez and his remarkable 32 years with Dover Motion as he begins his well-earned retirement. The afternoon was also a chance to wish the recently retired Perry Hamerla all the best as he starts his next chapter after 8 years with the team. Thank you both for your dedication, hard work, and the many contributions you've made over the years. Thank you to everyone who joined us for another memorable summer tradition! Whether we're engineering precision motion solutions or enjoying time together outside the office, it's our people and the relationships we build that make Dover Motion a great place to work. #DoverMotion #HengstlerDynapar #Ralliant #PrecisionMotion #Manufacturing #Engineering #Teamwork #CompanyCulture #EmployeeAppreciation #Retirement #WorkplaceCulture

When the depth of field gets to the nanometer scale, even a small sample tilt can push critical features out of focus. Our latest whitepaper examines why tip tilt stages are essential in precision imaging applications where angular alignment directly impacts image quality and measurement accuracy. In this whitepaper, we cover: ✅ How tip tilt stages correct flatness and alignment variation to keep the region of interest within the focal plane ✅ Why high-NA, high-magnification imaging systems are especially sensitive to sub-degree angular errors ✅ How tip tilt motion integrates with XY stages for more advanced multi-axis positioning ✅ A quantitative example showing how a high-NA water immersion objective can have a depth of field of only ~320 nm, making tilt correction essential For engineers building high-precision imaging systems, tip tilt is not just an adjustment feature — it is often a requirement for maintaining focus, alignment, and usable image data across the sample.

Low-force measurement usually means adding a load cell. But is that always necessary? Myth: You need a dedicated force sensor to generate or measure very small forces accurately. Fact: In the right motion architecture, the stage itself can do both. Why this matters: • Friction in conventional bearing stages can mask small forces • Non-contact air bearing stages reduce that limitation • Force can be generated and measured through motor current, encoder feedback, and control behavior • This can support tasks like touch-off, bondline control, and spring rate measurement • In some systems, it can reduce added hardware, size, and complexity Better force performance does not always come from adding more components. Sometimes it comes from choosing a motion solution that can do more. #ForceMeasurement #PrecisionMotion #Optics #MotionControl #AirBearingStages #PrecisionEngineering #DoverMotion

Engineers know that friction ruins more than just efficiency. So… why did the air bearing stage win at force measurement? Because it refused to let friction get involved. When force levels are small, mechanical friction can hide the signal you are trying to control. That is why non-contact motion architecture can make such a difference in low-force applications. #AirBearingStages #ForceMeasurement #PrecisionMotion #EngineeringHumor #MotionControl

When imaging performance depends on staying in focus, linear motion alone is not always enough. Tip tilt stages provide controlled pitch and roll adjustment to compensate for sample tilt, surface variation, and motion system flatness error. In microscopy, that matters because even small angular changes can move the sample out of the optical depth of field — particularly in high magnification and high NA applications. They are also often integrated with XY motion systems and customized to fit the application, helping minimize size, reduce Abbe error, and support better overall system performance. Beyond life science imaging, tip tilt stages are used in optics and photonics for aligning mirrors, lenses, prisms, and beam splitters, as well as in semiconductor and other precision applications where angular positioning is critical. Watch the video below to see how tip tilt stages support precision alignment and focus control. #PrecisionMotion #MotionControl #TipTiltStage #Microscopy #LifeSciences #Optomechanics #SemiconductorEquipment #DoverMotion

Most stages are built to move precisely. Far fewer can also apply and measure force with the same level of control. In this whitepaper, Dover Motion CTO Kevin McCarthy shows how air bearing linear motor stages can be used not only for high precision positioning, but also for precise force generation and low-force measurement. By combining frictionless bearings, direct-drive motors, and high-resolution encoder feedback, these stages can detect contact, control applied force, and measure spring rates with remarkable sensitivity. Kevin covers practical methods for precision touch-off, force control through following error and DAC output, and design considerations for getting accurate results in real applications. It’s especially relevant for engineers working in photonics automation and other precision systems where added sensors can increase complexity, cost, and error.
