Improper selection of the correct quality and type of machine vision lens can make your camera selection useless!
In many cases, we see customers attempting to choose a low quality lens for a camera that really needs quality optics to resolve the pixel sizes. Conversely, we also see customers trying to over specify a lens, where you simply need a lens that’s “good enough”
1st Vision has a white paper to help in the lens selection and provide valuable knowledge on various topics to make the best decisions.
Low cost imaging just got redefined with the new IDS UI-3130 LE USB3.1 model cameras. Typical entry level cameras previously had very few features, until now. IDS Imaging has released theUI-3130LE USB3.1 camera with the 1/4″ ON-SEMI Python 480 global shutter sensor. Providing 138 fps at full resolution and 420 fps with the 2X sub-sampling feature, the new series provides a great low cost entry level camera at 0.5MP resolution, and packed with many features
The new IDS UI-3130LEcameras are available in board level, board level with S-mount or fully housed configurations with monochrome and color sensors. The ON-SEMI Python 480 with 4.8um pixels is one of the latest image sensors providing low noise, high Quantum Efficiency and great sensitivity.
Feature Highlights Even with at a entry level cost, the UI-3130LE is packed with features such as 4X Multi Area Of Interest (AOI), long exposure settings to 5 seconds and Type C USB3.1 allowing external power output. High Dynamic Range (HDR) is included in the UI-3130CP model to address difficult imaging scenes where its desired to see the darks and brights without saturating or being too dim.
Example: Image to the right uses various “kneepoints” allowing HDR to be achieved
The HDR mode utilizes kneepoints, where the exposure time is divided into sections. After each section, excessively light pixel values are reduced to a limit value and briefly post exposed. This prevents overexposure and increases the dynamic range.
The uEye LE USB 3.1 Gen 1 is the first USB 3.1 Gen 1 industrial camerawith a pioneering, reversible USB Type-C connector which supports USB Power Delivery for the first time. The board-level versions also has a 10-pin I/O SMD connector for GPIO, trigger and flash. Via USB Power Delivery, it is possible to provide a variable peripheral power supply to the camera’s I/O connector. The new LE’s will also soon support liquid lens technology for OptoTune and Varioptics lenses.. Contact us to learn more about this upcoming feature.

Sony has continued to improve image sensors, first with the debut of the Pregius sensors and now with the low light sensitive Starvis sensors. The Starvis sensors are slowly being released by camera manufacturers and IDS Imaging is the first to release them in the new LE USB3.1 models. These new camera sensors are being released at an astonishing rate, which is great for the imaging market, but making it harder to make decisions in identifying the best sensor for an application. 1stVision is continuing to compare Sony image sensors to help make these decisions easier! We have put two more sensors into the boxing ring to battle it out and see how they fair in various categorizes. In this contest, we put the Sony Pregius IMX174 (and essentially its sibling, the IMX249) and the new Sony Starvis series, specifically the 2.1MP IMX290 in the ring. The Sony Starvis has become very interesting in applications that require very low light sensitivity and are attractive due to the back side illuminated architecture. As seen in the diagram below, the metal wiring has been set behind the photodiode and decreasing the distance light has to travel. This new pixel design lends itself to improved sensitivity.

The chart below compares some key attributes of the Sony Pregius IMX174 & IMX249 image sensors
Sensor Comparison Chart
Round 1 – Sensitivity: Absolute sensitivity is a great way to identify low light performance. Using the “Absolute sensitivity” figures above, we see that the IMX290 sensor takes less photons to register the smallest detectable amount of light. In this round, we see that the IMX290 has a lower value of 8.5 vs 12.1 (less photon’s needed) lending itself to the winner in this round for best low light sensitivity. In essence, we can start to form an image in lower light with the IMX290. Round 2 – Quantum efficiency (QE): QE is the ability to turn photon’s into electrons at given wavelengths. In this round, we see that the IMX290 has a better efficiency of 65.9% vs 59.2% in converting photons into a charge again winning the round. This means more signal is provided for that given wavelength, creating a brighter image. Round 3 – Saturation Capacity: This value is essentially the size of the pixel well measured in electrons. The larger the well, the better is can drown out noise and not saturate quickly. The IMX174 excelled in this round. In turn, you see the dynamic range is higher at 73% vs 66%. In cases where you would like to see the brights and the darks in a scene, higher dynamic range is desired. Conclusion: In the end, its really a draw between the two sensors. In the 2MP range of these sensors, it really depends on your application! If you need low light sensativity, the Sony Starvis family of sensors excel due to the pixel architecture. You’ll find the Sony Starvis currently in the IDS LE3.1 model cameras in the following cameras with 2 and 6 MP resolutions with more on the roadmap. 2MP – UI-3860LE 6MP – UI-3880LE If you need more dynamic range, the Sony Pregius IMX174 and IMX249 are the best CMOS sensors on the market today. (As a note, the IMX174 and IMX249 are identical, but the IMX174 being a faster version and a bit more costly than the IMX249). You’ll find these sensors in the several camera lines hosting the Sony Pregius sensors.

Do you need high camera data rates and reliable image transfer at rates at 6.25 Gbits / sec over a single cable reaching 100+ meters? CoaXPress (CXP) may be the perfect interface to solve your problems!
First, let us explain - What is CoaXPress (CXP) and its benefits? CoaXpress, established in March 2011, has become the worlds leading standard for high speed imaging in various industries from machine vision, medical imaging, life sciences and defense. Combining the simplicity of coaxial cables with state of the art high-speed serial data technology, CoaXPress is a very desirable solution for high speed imaging and data transmission. Click here for a list of CoaXPress camera options Benefits of CoaXPress (CXP) include:
6.25 Gbps per cable for image and data transfer with higher speeds using aggregate cables up to 25 Gbps!
Long Cable lengths up to 100 meters using standardized connections.
One cable solution can provide digital video, power, trigger and GPIO
Cost effective cable solutions which are hot pluggable.
Real time behavior with fixed, very low latency transmission.
Potential to re-use existing coaxial cable to upgrade image systems.
CoaXPress is an interface which requires a frame grabber on the host computer which communicates with the camera.
Teledyne Dalsa has recently adopted CoaXPress into the popular Xtium family of frame grabbers providing a robust solution based on the current Xtium platform. The Xtium-CXP PX8 is based on the industry standard PCI Express Gen 2.0 expansion bus to deliver high speed access to host memory over 8 lanes. Featuring a half length PCIe card with 4 input channels of up to 6.25 Gb/s, fully supported by Dalsa's Sapera LT SDK.
What is the key differentiator of the Xtium-CXP PX8 CoaXPress frame grabber? Free Run Time licences When using Teledyne Dalsa's Sapera processing library, the Xtium series offers free run-time licenses for Sapera processing standard Run-Time (RTL). The standard tools include access to over 350 highly optimized image processing functions and tools for area based search, blob analysis and image calibration! If you are already using Sapera processing, you have an immediate cost savings!
Trigger to Image Reliability framework The Xtium series support Sapera LT’s Trigger-to-Image (T2IR) framework for maximum reliability of the image acquisition system. The T2IR functions provide critical, real-time details of system events that help track and monitor acquisition, transfer, and control processes to ensure reliability of the imaging system. System up-time is increased and cost are lowered and all free of charge as part of the Sapera LT SDK.
The Teledyne Dalsa Xtium frame grabber series is well established with its flagship MX4 Camera Link frame grabber. If Camera link is your preferred interface, you'll find details on the Xtium-CL MX4 Camera link frame grabber here.
