To provide extensive optical solutions in machine vision optics systems, Canrill Optics, as a custom lens manufacturer, has been keeping developing, manufacturing and marketing telecentric lens for machine vision since 2009. In 2019 and 2020, Canrill Optics has successfully upgraded the telecentric lens to 4th generation PTL series and developed new series of non-telecentric Canrill lens.

Machine Vision Lens & Illuminator
Since 2009, Canrill has provided more than 1700 kinds of high-performance telecentric lens and illuminators for machine vision system. With the characteristics of extensive models, immediate delivery, cost-effective solutions and free customization service, Canrill can always be your first choice to select the most suitable machine vision lens and illuminators.

Types of Optical Lens & Illuminator
Wide range of high performance telecentric lens type supporting sensor size from 4.8mm to 82mm, characterized by high resolution, little-to-no-distortion, and good imaging consistency. We also provide a competitive optical lens price for customers.

Machine Vision Telecentric Illuminator
9 types of telecentric illuminator covering the beam diameter from 20mm to 238mm, offering higher edge contrast, and is recommended for high accuracy measurement.

Non-Telecentric Lens
Non-telecentric lens MH series is the latest series Canrill has developed in 2020, suitable for measurement and high-end positioning applications which do not require telecentricity. A supplement and replacement of FA lens and low resolution telecentric lens.

Microscope Objective Lens
Canrill miscroscopy lens VM series adopt modular design, different combinations can realize different functions. Major module consists of main body, illumination, horizontal imaging module, mount and other special parts.

How Does Machine Vision Work?
Machine vision is the application of a camera or several cameras to check and analyze objects automatically. Machine vision systems mainly depend on the digital sensors in industrial cameras. There are equipped with technical optics to obtain external vision, thus the computer can process, analyze, and measure various features for decision making. Machine vision is preferred to be applied in an industrial environment due to its high efficiency. Lots of manufacturers use automated machine vision instead of human inspectors because it is better suited to repetitive inspection tasks. It is faster, more objective, and works continuously.

Custom Machine Vision Lens & Illuminator From Canrill
Canrill catalog or product list on website only presents our most common models. Canrill also has an extensive of non-standard models in production. In addition, Canrill Optics offer customized machine vision lens or illuminators upon detailed request from customers. With rich experience both in optical design and mechanical engineering, and also our own optical factory and mechanical factory, Canrill is able to react fastest from design to prototype to mass production.

Canrill's record is 12 days to produce a complete imaging lens including design time.

Working Principle of Machine Vision System:
Lens Object FOV is a little larger than customer required FOV.

Lens Image FOV is equal or larger than camera sensor size.

Mag below 1X refers to low mag, above 1X refers to high mag.

There Are 3 Important Factors That Contribute In The Selection Process:
Image FOV, the sensor size of camera

Object FOV, the size of observed object

Working Distance

By image FOV and object FOV, the magnification of the lens can be acquired, that is image FOV/Object FOV.

Knowing the above, we can select a suitable lens optical from the existing product list.

Example:
Camera:1/2.5’-5MP

Sensor size: 5.7*4.3mm

FOV: 60*40mm

To pick a suitable lens, first to calculate the mag, 5.7/60=0.095X, 4.3/40=0.1075X.

Lower mag will be picked so as to cover full FOV.

From Canrill product line, Canrill fouth generation PTL series PTL-08 series is the most suiable, and the mag of XF-PTL09228 is 0.0847, is the closest figure to 0.095X.

Thus XF-PTL09228 is selected.
