Adimec will showcase our portfolio of machine vision products and technology at the 2014 edition of The Vision Show event in Boston, MA, held April 15- 17. We will display and discuss enhancements to our CMOS-based QUARTZ family, including the Q-12A65, which is now in full production, as well as other ultra high-resolution capabilities and latest CCD cameras.
The Adimec Quartz Q-12A65 camera offering 12 Megapixels at 66 fps is now in volume production. The Adimec Sapphire S-25A30 is also available with 25 Megapixels at 30 fps.
This week we completed extensive qualification and the latest member of the CMOS-based QUARTZ series, the Q-12A65, is now in volume production. The Q-12A65 has been designed into several instruments and is now commercially available to allow equipment manufacturers to take the next required performance leap in accuracy and throughput.
With the technology advances in CCD and CMOS image sensor market and the lower production costs driven by the consumer market, there is a steady increase in high-resolution (4 Megapixels and higher) and ultra high-resolution (12 Megapixels and higher) OEM camera options from machine vision suppliers. The higher resolution cameras enable advances in demanding inspection applications such as flat panel inspection, PCB inspection, but also in wafer and component inspections. System designers are able to increase FOV (field of view) (inspect more parts at a time), measure smaller details, and/or throughput by increasing resolution.
One of the big advances in image sensor development (both CMOS and CCD) is a reduction in read noise. Read noise is basically the noise added to the pixel when reading out the image sensor. The noise signal is added by the electronic circuits involved in the conversion of charge to the digital signal. With CMOS image sensors this process is all done on chip. With CCD, read noise is added both on-chip and off-chip as analog to digital conversion (ADC) is done off-chip.
At the Vision China in Shanghai, China from March 18th to 20th, imaging and photonics industry component suppliers will demonstrate their latest innovations and products.
Flat-Field Correction (FFC) can be done with both CCD and CMOS-based cameras to correct for sensor artifacts, lens artifacts, and illumination artifacts (shading). The purpose of flat field correction is to ensure image uniformity regardless of exposure.
Okay so we just talked about how you may not have to make a choice between a CCD or CMOS image sensor. However, since that is not the case at the moment (examples expected in 2015) what to do if you need to make an industrial camera selection now?
The latest requirements for 3D metrology and inspection in the semiconductor industry require high resolution and fast frame rate cameras. For these applications, CMOS-based cameras are required, with the trade-off of lower dynamic range and less sensitivity compared to CCD-based cameras. CMOS image sensors continue to get dramatically better fueled by the extensive resources and R&D in the consumer market, but what if it was possible to have no trade-offs?
There are many amazing new products and technologies unveiled and discussed at this week’s Photonics West Show. We are impressed at how many industries from agriculture to medicine are advanced by photonics.
