Calibration that gives researchers confidence in their in situ microscopy data.
Hummingbird Scientific’s internal Calibration Lab measures, inspects, and qualifies chips, holders, sensors, controllers, and custom systems used in in situ microscopy experiments. The lab supports TEM, SEM, X-ray, cryo-EM, gas, liquid, heating, biasing, electrochemistry, magnetizing, and other controlled sample-environment workflows.
Calibration is part of Hummingbird’s engineering loop, helping verify product behavior before shipment or deployment through calibration data, inspection records, qualification records, reports, and shipment documentation where applicable.
Key advantages
- Internal calibration connected directly to engineering, microfabrication, assembly, software, and microscope validation.
- Broad product-readiness support for Hummingbird chips, holders, sensors, controllers, and custom workflows.
- Thermal, electrical, magnetic, inspection, and documentation workflows in one engineering environment.
- Calibration data feeds back into design improvements, production checks, and application readiness.
- Careful use of appropriate calibration references and standards where applicable, without overstating traceability.
What we calibrate
Hummingbird calibrates and qualifies the hardware that creates, controls, and measures the sample environment in an in situ microscopy experiment. This includes microfabricated chips, device-level sensors, heater and biasing pathways, magnetic devices, controller behavior, holder assemblies, and custom configurations when applicable.
Chip and sensor calibration
For chip-based workflows, calibration can include temperature-response characterization, sensor calibration data, and IR camera-based calibration of on-chip thermometry. These measurements support closed-loop control and help verify that chips and sensors behave as expected before shipment or internal microscopy validation.
Electrical, magnetic, and controller qualification
The lab supports electrical signal analysis and stimulus-device qualification for biasing, heating, magnetizing, and control workflows. Power sources, oscilloscopes, optical inspection, electron microscopy inspection, and qualification records help verify device behavior before Hummingbird systems move into customer, custom, OEM, or internal validation use.
Why calibration matters in in situ microscopy
In situ microscopy data depends on the device that creates and measures the sample environment. Heating, biasing, magnetizing, gas, liquid, cryogenic, and custom workflows all rely on sensors, chip geometry, signal stability, mechanical fit, controller response, and microscope compatibility. Calibration helps identify behavior early, reduces avoidable setup risk, and gives Hummingbird engineers direct feedback for product improvement.
Connected to microscope validation
Bench calibration is only one part of product readiness. When applicable, Hummingbird connects calibration results with internal TEM and cryo-EM validation so hardware can be evaluated under real microscope conditions, including beam, vacuum, temperature, electrical, fluidic, cryogenic, workflow, and imaging conditions.
