Another thing to mention is the aperture, namely the hole on the lens to pass light through. If you want a deeper depth of field (DoF), you’d better get a lens with an aperture ring, since a decreased aperture will increase the DoF. If you have nothing to say about the DoF or you usually shoot from a further distance, a fixed aperture will be okay for your application.

C-mount lenses are adaptable optical instruments used in a variety of applications, such as machine vision systems for quality assurance, inspection, and production process monitoring. They are crucial parts of tracking, positioning, and object identification in robotics and automation.Their capacity to produce precise and detailed images is especially useful for capturing minute details of samples and tissues in scientific research and medical imaging. C-mount lenses are adaptable and versatile in a variety of fields, from helping robots manipulate objects to inspecting products on assembly lines.

On the contrary, Arducam offers many lenses tested on the IMX477 in M12, CS and C Mount, ranging from telephoto to fisheye lenses. Not only do we have datasheet for the lenses, tutorials are also available on how to select the right one for you.

However, the new change brings cost. You must spend extra money on the lens, and more time getting to know the lens. Simple as the old Pi cameras were, they saved most people from thinking about lens, which is not included in the Raspberry Pi High Quality Camera. But how would it work without a lens?

It is crucial to consider a number of factors when choosing the best lens for your machine vision application. The intended field of view, working distance, sensor size, and necessary focal length are some of these variables. Use our lens calculator to find the ideal focal length for your purpose and to assist you in choosing the correct lens. You can also use this tool to calculate the field of view for a C-mount lens.The fit between your industrial camera's pixel size and lens resolution, or resolving power, is another important factor to consider. The article "How to select the best lens resolution for the pixel size of your camera" has more information on this topic. The relationship between pixel size and lens resolution is explained in detail in this article.Our knowledgeable staff is here to assist you in choosing the ideal lens for your needs.

If you are using a CS-Mount lens, the adapter must be removed. However, for C-Mount lenses, the adapter is a must-have. Sometimes if you are still not able to focus a C-Mount camera even after the adapter is on, adjust the back focus. The gear-like ring on the main housing of the camera module is the back-focus adjustment ring, and you can spin it to alter the distance between the bottom of the lens and the IMX477 image sensor.

Arducam has been building customized Pi camera boards with interchangeable lenses as early as the V1 era, and we offer a wide arrange of lenses other than the officially endorsed 6mm and 16mm lenses. These lenses are also compatible with Arducam IMX477 High Quality Camera Modules.

One of the most popular lens types for industrial machine vision applications is the C-mount lens. This is because of its compact design and standardized thread. Our C-mount lenses are made to the exact standards of dependability and durability, which are necessary to withstand challenging circumstances like those present in the industrial settings. The C-mount lenses' features are designed to satisfy the demands of industrial image processing. They provide sharp images over an extended lifetime thanks to their high optical performance and precise focusing.We have nearly all of our C-mount lenses available on our local express stock. This indicates that they are prepared for shipping right away following an order. We also provide quick delivery for large orders of C-mount lenses. Numerous focal lengths are offered for each lens series. The majority of our C-mount lenses feature fixed focal lengths, which offer consistency for your application and allow for excellent contrast and resolution in photos that are taken. Because of this, they are perfect for use in industrial settings where set requirements like field of vision and working distance are required. Because fixed-focus lenses are relatively inexpensive, they may be able to accommodate the demands of large-scale industrial productions.

To ensure that the focus and aperture lens locking screws won't vibrate or loosen up in machine vision applications where the c-mount lens might, we recommend using blue Loctite® glue. The best practices for C-mount industrial lenses are as follows.

The CGL lenses recommended are at a reasonable price for the Raspberry Pi community, with the 6mm CS-Mount lens at $25 and the 16mm C-Mount lens at $50. We’ve purchased both, and admittedly, those are not bad. However, the issue is that we know little about the lenses just like this mysterious company – there is no detailed datasheet or specifications in the box, no other lenses available than the two, and even no way to contact them directly.

Cto CS-Mount adapter

The C/CS-Mount lenses look quite similar with the same thread size. However, the C-Mount lenses are designed with a longer back focal length than the CS-Mount, so we have a C-CS adapter for the Raspberry Pi High Quality Camera to use with C-Mount lenses.

If you need help with the Arducam products you’ve purchased, please include the following questions in your post and answer them to help us better understand your needs.

C-mount camera

Recently, the Raspberry Pi High Quality Camera has changed this situation by officially introducing the C/CS-Mount to Pi cameras. With a standard lens mount, this new HQ camera has access to much more lens options.

We offer more than fifty distinct C-mount lenses in our collection. GeT Cameras offers a wide range of high-performance lenses with varying focal lengths and sensor sizes for every resolution level (45MP, 25MP, 20MP, 10MP, 12MP, or 5MP). We also provide varifocal and macro lens options. Please contact us for custom C-mount lenses if you were unable to find what you were looking for in our online store or if your application called for a very specific solution that was not readily available in our portfolio. Our objective is to offer premium goods with a very low degree of variation between individual lenses.Do you require the ideal camera to go with your C-Mount Lens?

You can’t randomly pick a lens and expect it to perfectly match your applications, and there are some key factors you should take into consideration. You can also refer to our guide on how to choose a lens for the Raspberry Pi High Quality Camera.

Firstly, it’s the focal length. The focal length is the most concerning issue for most users to decide how wide the image frame you want to cover. The officially endorsed 6mm lens is usually advertised as wide angle, but it’s just slightly larger than the stock lens of V2, with a horizontal field of view at around 65 degrees. It’s the wide angle to be compared to the 16mm telephoto lens, but not the wide angle you might really need. You can refer to our focal length calculator page for more details.

For C-mount lenses, we provide a large selection of lens filters. You can enhance the contrast in your machine vision application by using our filters. A wide variety of bandpass, long pass, UV, NIR, and polarizing filters are available. Select the filter thread that fits your particular C-mount lens from a range of options. If your camera is CS-mount, all you have to do to incorporate it into your setup is match your C-mount lens with our C-EXTENSION-RING-5MM adapter.Using a focal extender, such as our 2x focal length extenders or 4x focal length extenders, is an additional option. To extend the focal length of a C-mount lens and zoom in by a factor of two or four. When using C-mount lenses with a microscopic, for instance, where the field of view is typically smaller, these focal extenders can be very helpful.

Previously, you could be unsatisfied with the stock lens, but it’s not an issue anymore – because the HQ camera has no stock lens. The Raspberry Pi chooses not to include a lens but have curiously endorsed a little-known reseller – CGL.

Lens is a crucial part in a camera system that needs flexibility. A single lens cannot meet all needs because the use case varies from one application to another. Sadly, V1 and V2 Pi cameras have glued stock lenses, which leave us little to customize. Take the Raspberry Pi Camera Module V2 for example, we have to swap the whole lens-sensor unit for Arducam IMX219 drop-in replacements to mount a different lens.

Shock and vibration tests are conducted on the industrial c-mount lens intended for Machine Vision applications. The lens is made to fit with pressure-ring-fixed glasses. Lenses are examined in the following circumstances:

While you are adjusting the lens, we recommend you put the camera module on a tripod. As the camera module now accommodates a much heavier lens, a tripod is handy for holding the camera steady. You can also check the official guide for more information.

C-Mount adapter

Once you’ve mounted the lens on, you will have to face the various kinds of handles on the ring of the lens. Typically, every C/CS-Mount comes with a focus ring, and many come with an aperture ring, while few may include a zoom ring. The trick to adjusting theses rings is you only tweak one ring at a time with the others fixed. Otherwise, they will move each other and ruin your last adjustment.

There are numerous advantages to using C-mount lenses because they are made especially for the use in industrial settings. In order to survive challenging circumstances like high temperatures, humidity, vibration, and other unfavorable elements, they are made to be strong and resilient. Other benefits include:

Three categories can be made out of our collection of standard C-mount lenses according to their focal length, aperture, and optical design:

If you are really considering a wide-angle application, usually with an HFoV greater than 100 degrees, consider other options including the C-Mount Zoom lenses and M12 Lenses from Arducam. The zoom lens is helpful if you need to switch between a wider view and a narrower view from time to time, and the M12 lenses can push the field to the fisheye level.

The annual production capacity of our manufacturing facility is over 300,000 lenses. Specifically, we have 500 units of machine vision lenses in stock. These lenses are painstakingly crafted and polished to achieve the exact aspherical size. Glass elements are cut, polished, and thoroughly cleaned during the first production step of this metal-encased glass construction. Our C-mount lenses have an exceptional price-performance ratio and meet strict quality standards thanks to the implementation of strict quality control measures.
