The Basler boost boA4504-100cm pairs a 1.1-inch Sony IMX531 global-shutter CMOS sensor (4504 x 4504 px, 20 MP, 2.74 µm pixels) with a dual-channel CoaXPress 2.0 (2x CXP-12) interface delivering up to 12.5 Gbps per channel. It reaches up to ~100 fps at full resolution and is powered with 24 VDC over PoCXP or the I/O connector. The camera is monochrome, uses a C-mount, and complies with the CoaXPress 2.0 and GenICam standards, targeting high-bandwidth applications such as semiconductor, electronics, and print inspection.

The Basler boost boA4504-100cm is a 20 MP monochrome area-scan camera built around the 1.1-inch Sony IMX531 Pregius S CMOS sensor, delivering a square 4504 x 4504 pixel active image on a 2.74 µm pitch. The square format and dense pixel grid make it well suited to inspecting square or near-square parts (wafers, panels, PCBs, printed sheets) where a traditional 4:3 sensor would waste field of view in one axis. Because the sensor uses a true global shutter, every pixel integrates simultaneously, so fast-moving or indexed parts are captured without the skew and smear that a rolling-shutter device would introduce. As a monochrome camera it puts all 20 MP toward luminance detail with no Bayer interpolation, which maximizes effective resolution and contrast for defect, surface and dimensional work where color is not the discriminating feature.
The defining feature is the dual-channel CoaXPress 2.0 interface (2x CXP-12, up to 12.5 Gbps per channel). That bandwidth is what lets the camera sustain up to ~100 fps (102.86 fps max) at the full 20 MP resolution over the stated 2x CXP-12 link at 24 V, a throughput that USB3 or single-cable GigE simply cannot carry at this pixel count. CoaXPress also runs over long coax cable, supports power-over-coax (PoCXP), and provides a deterministic uplink for triggering, so the camera can be placed away from the frame grabber and still receive precise hardware triggers. Plan for a CoaXPress 2.0 / CXP-12 frame grabber with two channels and the matching cabling; the camera complies with the CoaXPress 2.0 and GenICam standards, so it integrates with GenICam-compliant grabbers and software.
Mechanically the camera ships in a 45 x 80 x 80 mm box housing at 442 g, draws 11.9 W, and is powered from 24 VDC (18.6 to 26 VDC) via PoCXP or the I/O connector. It uses Basler's universal front with a C-mount option (F-mount and M42 are also offered), but note that a 1.1-inch sensor (12.3 x 12.3 mm, 17.5 mm diagonal) at this resolution demands a high-resolution lens whose image circle matches the format and whose resolving power suits the 2.74 µm pixels, so lens selection is as critical as the camera itself. The operating range is 0 to 50 °C. The combination of global shutter, high frame rate and 20 MP detail makes this a camera that pairs naturally with bright strobed lighting synchronized to the hardware trigger, keeping motion frozen and exposure short at speed.
Best for
Semiconductor and wafer inspection where the square 4504 x 4504 sensor matches square die/wafer fields and 20 MP resolves fine features
High-speed electronics and PCB surface inspection on indexed or continuously moving lines, using the global shutter to freeze motion at up to ~100 fps
Print and web inspection of sheets or panels needing high-resolution defect detection across a square field of view
Dimensional measurement and metrology where global-shutter geometry and 2.74 µm pixels support accurate edge and gauging measurements
High-bandwidth packaging inspection that requires full-resolution capture at high frame rate over a long CoaXPress cable run
Selection notes
Requires a CoaXPress 2.0 frame grabber with two CXP-12 channels; the ~100 fps full-resolution figure (102.86 fps max) is specified for the 2x CXP-12 link at 24 V, so a single-channel or lower-grade grabber will reduce achievable frame rate.
The 1.1-inch sensor (12.3 x 12.3 mm, 17.5 mm diagonal, 2.74 µm pixels) needs a high-resolution lens whose image circle covers the format and whose MTF resolves the small pixel pitch; an undersized or low-resolution lens will throttle real-world resolution. C-mount is the listed option, with F-mount and M42 also available.
Monochrome only: choose this camera where contrast, defect or geometry, not color, drives the inspection. If color discrimination is required this sensor will not provide it.
Budget for adequate strobed or high-intensity lighting and short exposure: at ~100 fps and 20 MP the light needed to fill each frame is significant, and the global shutter is best exploited with triggered strobe illumination.
Power and integration: plan 24 VDC (18.6 to 26 VDC) via PoCXP or the I/O connector, 11.9 W, a 45 x 80 x 80 mm box footprint at 442 g, and a 0 to 50 °C operating envelope when designing the enclosure and cabling.

Get a first image quickly with the pylon Viewer, then move into the pylon SDK for your application. These cameras are GenICam/GenTL-compliant, so any compliant vision software can drive them as well.
Download and install the pylon Camera Software Suite for your OS from Basler. This provides the pylon Viewer, the GenTL transport-layer producers and the pylon SDK (C/C++/.NET/Python). On Windows the installer adds the needed drivers; on Linux follow the included setup notes for USB and network permissions.
2. Connect the camera and check the link
Cable the camera to its matching interface: GigE Vision to a GigE port (use a quality cable and, ideally, a dedicated NIC with jumbo frames enabled), USB3 Vision to a USB 3.x port with the supplied cable, or CoaXPress to the frame grabber. Provide power where required (PoE, USB bus power, or PoCXP). Open the pylon Viewer and confirm the camera appears in the device list; for GigE, make sure the camera and NIC are on the same subnet.
3. Grab a first image and set exposure, gain and pixel format
Select the camera in the pylon Viewer and start a continuous grab. Adjust exposure time and gain until the image is well exposed (avoid clipped highlights), set the pixel format (e.g. Mono8 or a Bayer/RGB format), and focus the lens. Use a test pattern if the lens or scene is not ready yet.
4. Configure triggering and acquisition
Decide between free-run and triggered acquisition. For synchronized capture, set the trigger source (software or a hardware line on the I/O connector), trigger mode and any debounce or exposure mode, then verify timing. Note the parameter names you change in the Viewer feature tree, as you will reuse them in code.
5. Move to the SDK or a GenICam-compliant library
Recreate your settings in code with the pylon SDK (C, C++, .NET or Python) to open the device, apply the same features and pull frames into your pipeline; pylon vTools and pylon AI can add processing blocks. Because the cameras are GenICam/GenTL standard, third-party vision libraries work too. Once the image stream is stable, you can route frames to a deep-learning inspection such as Rosepetal for automated defect detection.
