InGaAs camera


The C16741-40U is an InGaAs camera with sensitivity in the visible to near infrared region from 400 nm to 1700 nm.

It has a USB 3.1 Gen 1 interface port which supports 12 bit image acquisition and exposure time adjustment. This makes the C16741-40U ideal for use in a wide range of applications including internal inspection of Si wafers, chips, and MEMS, laser beam alignment and evaluation of solar cells.


  • High sensitivity in the visible to near infrared region
  • 1280 pixels × 1024 pixels
  • Low noise and high stability with cooling
  • Frame rate of 71.53 frames/s


  • Inspection of internal defects in Si wafers, chips, and MEMS
  • Evaluation and analysis of optical communication devices such as IR beam profilers
  • Evaluation of semiconductor materials such as solar cells 
  • Inspection of food and agricultural products
  • Moisture detection
  • Observation of cultural assets


Our software provides the interface to access all of our carefully engineered camera features, from simply setting exposure to orchestrating complex triggering for multidimensional experiments.
