QHY5III178 6.0mp 50FPS high resolution Back Illumination CMOS Camera


QHY5III178 uses IMX178 STARVIS Exmor-R back illuminated CMOS sensor. 6.0mega pixels. The QHY5III178M can be regards as a new guide camera since its smallest pixel size and high sensitivity and a good FOV(1/1.8inch). QHY5III178 sensor is the sony's StarVis BSI image sensor. STARVIS is a trademark of Sony Corporation. The STARVIS is back-illuminated pixel technology used in CMOS image sensors for high sensitivity applications.


The unique QHYCCD design keeps the 1.25inch eyepiece design and a more efficient heat transfer to the outer case enabling lower noise especially in high ambient temperatures. In addition, the QHY5III178 uses the LEMO style connector for the guide port. These connectors are known for being both rugged and reliable connectors. Unique to QHY5III cameras is the built in anti-amp glow circuity. The new Sony CMOS chips develop amp glow with longer duration images. Dr Qiu has taken the time to eliminate or reduce the problem through advanced design of the camera. See the examples shown here:
