BRIDGEWATER, N.J., March 3, 2011 — Hamamatsu Corp. has introduced a board-level camera for OEMs. The C11440-50B is based on a next-generation scientific CMOS image sensor and combines high resolution, sensitivity and speed, and low noise.
At the camera’s core is the FS-280 scientific CMOS image sensor, which features 2.8 megapixels and a pixel size of 3.63 × 3.63 µm, ensuring high resolution. The sensor’s wavelength sensitivity ranges from the UV to the near-IR, with peak sensitivity of >60% quantum efficiency at ~450 to 500 nm. The sensor features low readout noise of 3 electrons rms, typical. Its design keeps the readout noise minimal, even at readout speeds ranging from 45 fps at full resolution to 1273 fps with subarray readout. The image sensor has a wide dynamic range of 4500:1.
Two IEEE1394b (FireWire) interfaces offer low-cost communication and power, while external trigger options enable seamless integration with the OEM customer’s equipment. The camera is suitable for a variety of imaging applications, including life sciences imaging; high-speed calcium imaging; and Förster resonance energy transfer, fluorescence in situ hybridization, total internal reflection fluorescence and real-time confocal microscopy. Other applications include semiconductor inspection; industrial, ratio and time-lapse fluorescence imaging; live cells expressing green fluorescent protein; micromorphotological observation; failure analysis; and x-ray scintillator readout.
External trigger and timing output functions include global exposure, synchronous readout and start trigger; trigger delay; and programmable and global exposure timing, and trigger-ready output.
Other features include 2 × 2 binning, analog gain of 1× to 8× in 256 steps, an 8- or 12-bit analog-to-digital converter, exposure time of 20 µs to 1 s and a C-mount lens.
