We are excited to be shining the spotlight on ourselves today as we introduce for the first time our new logo and website user interface (UI) design . Our new logo signifies our continuous high-level commitment to all your machine vision needs and captures the new foundation laid by a capital investment by and strategic partner relationship with Next Imaging.
On February 7, 2020,we announced that 1st Vision had been acquired by Next Imaging but would continue doing business as 1st Vision, Inc. We are keeping our well-known identity and presence in the North American Market and looking to excel even further at becoming your 1st choice for all your imaging requirements.
1st Vision’s sales engineers have an average of 20 years experience to assist in your camera selection. Representing the largest portfolio of industry leading brands in imaging components, we can help you design the optimal vision solution for your application.
Long Wave Infra Red (LWIR) cameras have been used for industrial applications to detect infrared light in the 8-14um wavelength region. This infrared light is invisible radiant energy that we experience as heat but can not see. Applications for LWIR cameras continues to expand past industrial applications now entering into medical markets such as fever screening.
Teledyne Dalsa has expanded the Calibir LWIR camera series introducing the latest Calibir GXM model now with radiometric capabilities. With outbreaks of infectious diseases such as Covid 19, LWIR cameras can be used for fever screening by detecting elevated skin temperatures. Using optics, the cameras provide the ability to take the temperature of individuals keeping save distances between patients and medical practitioners.
All cameras are factory-calibrated for reliable radiometric performance, have outstanding dynamic range and allow the best possible NETD over a vast range of temperature (>600C). . Coupled with many features such as multiple ROI, color maps, LUTs and the ability to sync and trigger multiple cameras, makes the Calbir GXMa good solution for many thermal imaging applications.
Example: Thresholding with Look Up Table (LUT) allows the Calibir GXM to mark certain temperatures with color while leaving the rest in monochrome.

We are excited to announce that 1stVision has been acquired by Next Imaging as of February 7, 2020. We will be doing business as 1stVision, Inc. keeping our well-known presence in the imaging market for the foreseeable future and continuing to serve the North American Market at the highest level. Industry veteran Mike Troiano[has joined us to expand our presence and knowledge.
Next Imaging also owns Image S SpA, the largest imaging distributor in Italy. Next Imaging’s focus is to build a strategic platform for imaging distribution in the American and European markets. Together we are the only distribution partner in the world to service both North America and Europe for many of our principals.
We have helped deploy nearly 100 systems since early March for the detection of COVID-19 and for diagnostic systems to help patients recover. Global suppliers have supported us with lead times in as short as 4 business days for products that normally take 4-8 weeks in our fight. As the North American market’s largest supplier of imaging components, we have been sited by several of the world’s top healthcare organizations as a key partner and an essential supplier during this time. We remain open for business Monday through Friday 8-4PM EST.
During the difficult time caused by the COVID-19 pandemic, we look forward to a bright future supporting our existing and new customers for medical, industrial and emerging imaging applications.

The image fidelity achievable from a machine vision camera is only as good as the optics you use! Many of the machine vision cameras used today utilize very small pixels, down to 1.25um. The crispness of the images are a result of the resolution of your machine vision lens, so matching the right lens to the camera sensor is extremely important. We classify the lens resolution in terms of line pairs per millimeter (lp/mm). So, what lenses can help resolve these small pixels?
First, the relationship of pixel pitch can be put in terms of lp/mm as seen in the chart to the right. Machine vision lens manufacturers today typically provide the resolving power on their data sheets to help in the lens selection and ensure your matching the lens to the image sensor. If not matched properly, image contrast will suffer.
For machine vision cameras with small pixels, the Moritex ML-M-UR “Ultra high” resolution lenses are an excellent choice with the capability of resolving pixel pitches down to 2.2um with good contrast.
The comparison images below show the Moritex ML-M-UR series compared to a conventional lens with less resolution. As you can see in the cutout of the corner, the contrast is much higher with lenses with high resolving power.
Left (High resolution lens) Right (Legacy lower resolution lens)
Lens resolution typically has fall off to the edges of a lens. To maintain high contrast, Moritex has optimized the ML-M-URseries to have good resolving power to the edges of the lens.
The charts below represent the contrast (MTF) corresponding to image height (x-axis ) showing the contrast from lens center to lens edge. The X-axis represents the center starting at zero millimeters and mapping MTF to the edge (furthest right point) The ML-M-UR shown in the left chart demonstrates very good performance across the lens. (A relatively flat line is good!) As a comparison to another lens (right chart), contrast is degraded across the lens from center to edge.
Aside from high resolution, The Moritex ML-M-UR series are a compact, 29mm diameter design and well suited for typical 29mm cube cameras. Additionally the lenses have an anti-vibration design with maximum acceleration to 10G’s.
Give us some brief idea of your application and we will contact you to discuss camera options.
