CMOS industrial cameras have changed how we perceive “High Speed” imaging. If we look back 5+ years ago, “High Speed” imaging pertained to specialized cameras for event capture which were relatively expensive. CMOS image sensors used in standard industrial cameras today have opened up the door due to the ability to achieve up to 2000 frames per second with excellent image quality at prices starting < $500! These new application areas range from sports analytics, process monitoring to event capture.
This video tutorial addresses several topics when using standard CMOS cameras in high speed applications. Topics covered as follows:
Application areas using the latest CMOS cameras.
Evolution of sensor technology from CCD to CMOS
Considerations in components used in high speed applications
Sensor and camera features supporting high speed imaging.
Higher speed interfaces on the horizon

The Sony Pregius image sensors are becoming the workhorse in industrial cameras providing various resolutions, coupled with high dynamic range and unsurpassed sensitivity. However, the latest pixel architecture from Sony has moved to a 3.45um pixel pitch which results in more demand on the lens resolution. It becomes even more challenging on high megapixel and small format image sensors such as the ON-SEMI MT9P031 or AR1820HSwhich have 2.2um and 1.25um respectively. To be successful in imaging with these sensors, a lens design must provide the ability to resolve the small pixels ideally to the edge of the lens or image contrast will degrade. In many cases, this is stated in terms of line pairs per mm (lp/mm) from center to edge (i.e 120/100). Read more about lens specifications in our “Demystifying Lens performance specificaions” blog How do we overcome this problem to ensure a high contrast image? FUJI 12 Megapixel HF-12M series lenses! Although lens manufacturers tout a lens series in Megapixels, the key is understanding the lens performance data in terms of its resolution. The FUJI HF12M series states “12 Megapixels”, but really is a lens designed to resolve 2.1um pixels on a 2/3″ sensor which accommodates 12 megapixels. The bottom line is that any image sensor with small pixels down to 2.1um regardless of resolution benefit from this lens.. This lens will help resolve the pixel! The HF-12M series is great for cameras using image sensors from Sony’s Pregius IMX Series (ie IMX250, IMX252, IMX264) which have 3.45 um pixels along with ON-Semiconductors MT9P031 or AR1820HSsensors.
When the iris (aperture) is set at the orange F4 marker on the lens barrel, the HF-12M series delivers the resolving power greater than 2.1um pixel pitch.
The HF-12M series is capable of maintaining ultra-high definition with a 2.7um pixel pitch within the whole frame area.
The series brings out maximum performance of the popular Sony Pregius image sensors with a 3.45um pixel pitch.
Unique “4D” High Resolution performance General machine vision lenses share the issue of resolution degradation when the working distance or aperture is changed. The HF-12M features Fujinon lenses unique “4D High Resolution” performance. It maintains a high level of consistent image sharpness at the center as well as the edges, while mitigating resolution degradation that typically occurs when changing a working distance or aperture value. Ease of installation and high reliability
Compact form factor across five models with 33mm diameter
Most lenses use iris and focus locking screws with protruding heads causing interference. The HF-12M series come with regular as well as headless compact screws to minimize interference
Built with metal barrel for durability and robustness.
Industry-leading low distortion design of no more than 0.05% Unique optical design minimizes troublesome distortion. The series boasts an industry-leading low distortion rate of not more than 0.05%

Manta G-319 & Manta G-507 with SONY PregiusTM CMOS Sensors added to the portfolio Allied Vision adds two new camera models with the very popular Sony PregiusTM CMOS sensors to its high performance camera portfolio. These new global shutter sensors outperform traditional global shutter CMOS sensors by having a high saturation capacity and very low noise resulting in an exceptional dynamic range. (Learn more about the Pregius sensors here) The Manta G-319 powered by the 3.1 megapixel Sony Pregius IMX265 sensor, and the Manta G-507 utilizing the 5.0 megapixel Sony Pregius IMX264 sensor will provide great options for high quality imaging. Due to their superior performance, these cameras will be the best candidates to replace existing CCD cameras with similar resolution and optical formats.
The Manta is Allied Vision’s most versatile GigE Vision camera with a wide range of features. Particular highlights include:
On-board image processing features such as look-up tables and sophisticated color correction capabilities.
Numerous modular concept options – including angled heads and board level versions to facilitate the integration in almost any application.
Trigger over Ethernet (ToE) Action Commands feature – ToE enables to externally trigger GigE cameras in a network through the Ethernet cable. This means that Manta cameras can now be triggered via its Power over Ethernet connection and enable users to realize single cable solutions with data, power and trigger capabilities. Furthermore, all action command related configurations can be saved in the camera’s user sets.

The Calibir™ uncooled thermal imaging long wave infrared (LWIR) camera platform offers outstanding shutter-less imaging performance and great flexibility in a very compact package. With a frontal form factor of 29mm x 29mm the camera can be integrated in tight spaces for compact solutions. The microbolometer-based, ITAR free platform covers wavelengths from 8-14 µm and supports a variety of camera interfaces, lenses and state of the art on-board processing features. This serves a wide range of today’s uncooled imaging applications with an architecture that offers more capabilities and possibilities for the future at an economical price.
Long Wavelength infrared imaging detects infrared light in the 8-14um wavelength
region, which is invisible radiant energy that we experience as heat but can not see. At temperatures above absolute zero (-275.15 deg. C), everything emits thermal radiation. The warmer an object, the more radiation it emits making warm objects stand out against cooler backgrounds.
Long wavelength Infrared cameras are one of the more commonly used IR cameras. These cameras are based on microbolometer focal plane arrays which converts infrared energy into an electronic signal which is processed and then produces an image.
An example to the right shows a false-color thermal image taken with a microbolometer camera. The image shows hotter (redder) and cooler (bluer) areas where temperatures vary by 10 °C, indicating increased blood flow caused by inflammation in a medical application.
As size, weight and cost decline and performance increases, an ever widening range of applications is opening up.
Application examples include:
Medical Imaging – Detect inflammation, cancer and other diseases
Unmanned airborne and ground vehicles – Object avoidance, detection of wildlife
General Machine Vision – Detect features not visible to standard cameras.
As an example, the video below reveals the difference between hot and cold liquids poured on the ground; it also shows the heat signatures of a motorcycle’s engine and tire.
Benefits of the Calibir LWIR camera Unprecedented Ease of use – Using Teledyne Dalsa’s established SDK and control tool (CamExpert), installation to image capture can be accomplished in minutes! Connect and Go! Watch the video below demonstrating how quickly you can start capturing images.
Size & Weight – With a 29 x 29 mm frontal form factor @ 30 grams (w/out lens), this is ideal for drones to designing into compact spaces. Shutterless Operation The Calibir camera requires no mechanical shutter for calibration, meaning instant image output and no interruption for recalibration. The image output of the Calibir camera remains stable across time and temperature range, freeing your application the the inconvenience, size, and additional complexity of failure prone mechanical shutters.
