Designing minimally invasive medical instruments, catheter-based diagnostic tools, and micro-industrial non-destructive testing (NDT) systems requires a precise balance between physical dimensions and image fidelity. The OCHTA10 Endoscope Camera Module addresses these spatial limitations by integrating a sub-millimeter 0.9mm optical assembly with a decoupled, separated circuit architecture.
Built by SincereFirst using automated Active Alignment (AA) assembly lines, this module delivers real-time video over a plug-and-play interface for applications where standard camera footprints cannot be integrated.
Conventional camera module designs are physically limited by the co-location of the image sensor and peripheral logic components on a single substrate. The OCHTA10 module bypasses this physical bottleneck through a separated structural layout.
Ultra-Miniature Tip: The camera head houses only the lens assembly and raw sensor die, interconnected via fine bonding wires to a remote main processing board (measuring approximately 14.0 × 46.0 mm).
Thermal Management: This structural decoupling allows the imaging tip to maintain an outer diameter of just 0.9mm. Engineering teams can route the flexible micro-probe through highly restricted channels—such as vascular catheters, small-bore urological endoscopes, or internal turbine blade gaps—while keeping heat-generating power management and backend ISP circuitry localized at the host-side interface.
Capturing usable spatial data at a sub-millimeter scale requires optimizing pixel architecture to counter low photonic capture rates. The OCHTA10 module utilizes OmniVision’s PureCel® Plus-S stacked die technology, arranging a 400 × 400 pixel array with a 1.008μm pixel pitch.
The back-illuminated (BSI) stacked architecture maximizes the fill factor of each micro-pixel, minimizing dark current and readout noise. This performance profile ensures clear structural definitions inside unlit cavities (e.g., anatomical lumens or mechanical gearboxes) when paired with fiber-optic or micro-LED illumination channels.
The fixed-focus lens features an ultra-short effective focal length (EFL) of 0.175mm and a fast F2.8 aperture. Optimized for near-field inspection, it maintains high MTF contrast across a focusing depth of 3mm to 30mm. While wide-angle miniature lenses often introduce severe peripheral warping, the OCHTA10 optical train constrains TV distortion to less than -11% across a symmetric 100° H × 100° V Field of View (FOV), preserving spatial proportions across the entire matrix.
From an electronics integration standpoint, the module operates as a standard Universal Video Class (UVC) compliant device over a USB 2.0 bus via a 5-pin Micro USB connection.
Driverless Cross-Platform Operation: The hardware supports dual-stream formats—compressed MJPEG for bandwidth-efficient 30 FPS output and raw YUV for direct pixel manipulation. It interfaces natively with embedded Linux architectures, Windows workstations, and Android edge platforms without requiring custom kernel-level device drivers.
AA Optomechanical Tolerances: At a 0.9mm scale, even a 1-micron mechanical displacement destroys image symmetry. SincereFirst mitigates this variance by utilizing automated Class 10/100 COB assembly lines equipped with 6-axis Active Alignment systems. The lens position is dynamically optimized while the sensor actively images a target grid, ensuring consistent corner-to-corner sharpness.
Global Compliance: The modules carry full CE, FCC, RoHS, and Reach compliances to meet strict regional deployment criteria.

Medical Devices & Diagnostics: Single-use disposable bronchoscopes, cystoscopes, hysteroscopes, and micro-catheter imaging assemblies where autoclave reprocessing costs must be eliminated.
Industrial Non-Destructive Testing (NDT): Internal inspection of aviation turbine compressor blades, micro-bore pipe welding seams, automotive cylinder walls, and multilayer high-density PCB trace cross-sections.
Scientific Instrumentation: Microfluidic chip observation channels, real-time biological sample analysis, and robotic micromanipulator vision systems.
Q1: Can this module be integrated directly into single-use/disposable medical systems?
A: Yes. The OCHTA10 module architecture is optimized for single-patient-use medical devices. By leveraging automated high-volume COB assembly, SincereFirst controls manufacturing overhead to a point where component disposal is commercially viable, eliminating hospital sterilization costs and cross-contamination risks.
Q2: What are the exact integration advantages of the "Separated Design"?
A: Decoupling the imaging sensor from the bridge controller allows the probe tip to remain at a 0.9mm diameter profile. Heat dissipation from logic circuits occurs entirely at the rear processing board (14.0 × 46.0 mm), preventing thermal damage to sensitive biological tissues or environment monitoring elements at the probe tip.
Q3: How does the module handle zero-light environments?
A: The OCHTA10 utilizes back-illuminated pixel physics which route incoming photons directly into the photodiode without obstruction from metallic routing layers. When paired with external illumination (such as a ring of micro-LEDs or a fiber-optic light guide integrated into the probe sleeve), the F2.8 optical train provides clean structural definition down to 1 lux.
Q4: What level of hardware customization can SincereFirst support for this module?
A: We provide component-level modifications for volume integration. This includes modifying the flexible bonding wire length, adding rigid stainless steel or biocompatible polymer outer sleeves, integrating custom LED illumination arrays on the tip, and re-routing the host-side PCB geometry to match your specific hardware layout.
Q5: Is SincereFirst a trading entity or a direct manufacturer?
A: SincereFirst is a direct high-tech optical manufacturing enterprise based in Guangdong, China. We operate 33,350 square meters of production facilities, including Class 10 and Class 100 dust-free COB automated production workshops, allowing us to maintain direct technical accountability from initial engineering samples to million-unit mass production.
