Allied Vision’s high-resolution Prosilica GT now with 12, 16 and 25MP ON Semi PYTHON sensors

Allied Vision extends its Prosilica GT Large Format camera platform with three high-resolution ON Semi PYTHON image sensors (Python 12K, Python 16K & Python 25K)

Combined with robust thermal housing designed to operate in extended temperature ranges and fluctuating lighting conditions, the new Prosilica GT Large Format cameras are ideal for high-definition imaging applications with demanding requirements of robustness and design-in flexibility. They provide a great option for high-quality imaging for anyone looking to switch over from existing CCD cameras to CMOS cameras with similar resolutions and optical formats.

Now that you have a great high resolution camera, what lens works best?

High resolution cameras with the ON Semi Python sensors are great, but only as good as the lenses you use! It is imperative to have the sensor sizes matched with the lens formats. Additionally, we need to make sure the lens resolution is adequate for the image sensor pixel size.

To aid in the lens selection, we have the following recommendation on lens series. Recommendations as follows

Prosilica GT5120, 5120 x 5120, 25MP: This camera has a 32.58mm diagonal image sensor, so a F-mount lens is required. Two options are Kowa and Schneider
KOWA – F mount series
Schneider – F mount series

Prosilica GT4096, 4096 x 4096, 16MP: This camera has a 26.06mm diagonal image sensor, also requiring a F-mount lens.
KOWA – F mount series
Schneider – F mount series

Prosilica GT4090, 4096 x 3092, 12MP : This camera has a 23.09mm diagonal image sensor which falls into a 4/3″ format.
KOWA 4/3″ lens series

As a note, as the pixel size is 4.5um, this is not as demanding on the lens resolution and will only require 111 line pairs/mm (lp/mm) making these adequate selections.

Learn how liquid lenses keep continuous focus on machine vision cameras when the working distance changes.

Optotune lenses solve a machine vision industry problem!

so
Machine Vision applications requiring the inspection of objects at various heights can become a challenge as normal lens have limited depth of field. Objects outside of the depth of field become out of focus, limiting the vision application. Historically, a lens with motorized focus adjustment would be implemented adding complexity, cost and long cycle times. In reality, this challenge is applicable to any imaging application requiring refocusing due to various lens working distances.

Optotune Focus tuneable lenses solves this problem eliminating motorized zoom lenses or manual intervention.

Click here NOW for full detail specifications on tunable lenses

Adding an Optotune tunable liquid lens to the optical system on a standard C-mount lens and camera, allows refocusing of the imaging system on the fly. When used in conjunction with distance sensors, its possible to inspect objects of various heights, refocusing within 15 milli-seconds.

For example, vision systems using 8mm to 50mm focal length lenses can be equipped with a tuneable lens in the front, typically mounted on the filter thread. In this configuration it is possible to focus from infinity down to about 100mm or less if spacers are added.

This solution can be applied to industrial machine vision applications, ophthalmology, laser, microscopy, postal, packaging and laser applications to name a few.

Technology 411

Optotune’s focus tunable lenses are shape-changing lenses based on a combination of optical fluids and a polymer membrane. The core element consists of a container, which is filled with an optical liquid and sealed off with a thin, elastic polymer membrane. A circular ring that pushes onto the center of the membrane shapes the tunable lens. The deflection of the membrane and with that the radius of the lens can be changed by pushing the ring towards the membrane or by exerting a pressure to the outer part of the membrane or by pumping liquid into or out of the container.

Watch this video to see the Optotune liquid lens in action

Advantages

A change in lens radius of several micrometers can have the same optical effect as moving the entire lens several centimeters. In turn there are several advantages

Optical systems can be designed more compact, oftentimes with less lenses and usually with less or no translational movement.
Large working distance ranges can be achieved
Eliminate expensive mechanical actuators resulting in a more robust design, which can be completely closed so that no dust can enter. Essentially no moving parts for long life cycles (> 1B cycles)
Weight and volume is reduced in the system.
Low power consumption.
Fast response time of systems, down to the order of milliseconds.
Easy installation and remote focus control
Advanced controls for very accurate and repeatable control of the lens using Gardasofts TR-CL180 controllers

Popular Sony Pregius Image sensors expand camera lines with 3.1MP and 5MP resolutions – Download the comparison chart!

Sony’s popular Pregius (IMX) image sensors have expanded the camera offering with 3.1MP and 5MP resolutions.

This sensor has continued to impress us with high dynamic range, low noise and excellent sensitivity. (Learn more on this image sensor here )

As debuted in the 2.3MP, IMX174 and IMX249 sensors, the image sensors are released with slow and fast versions of a given resolution. This directly translates to lower and higher cost cameras within a given resolution. In cases where you do not need speed, you can benefit from the great performance without paying a premium for speed. Speed is there if desired, but at a small premium.

This has provides camera manufacturers a nice price vs performance offering covering various resolutions… and the offering will continue to expand.
