The calculators below will help you determine the lens focal length you need. It is assumed the camera's sensor has a aspect ratio, the sensor is a common size, and that you will use all the pixels. Or, try our new Machine Vision Lens Calculator instead.

It is more flexible, and is smart enough to suggest specific lenses for your next project. Complete the fields below to calculate the aproximate working distance.

This is the distance between the lens and the object to be imaged. These lens calculators are for general purpose entocentric machine vision lenses. Not sure about your camera's sensor size? What more precise results? If your camera or image sensor is in our store, we suggest accessing the calculator via the link on the Resources tab of the associated product page.

Lens Focal Length mm. Calculate Field of View. Complete the fields below to calculate the aproximate field of view. With the exception of lens focal length, the parameters you enter may be in any dimensional unit mm, cm, inches, or whatever. The result will be in the same dimensional unit.

Lens focal length is always in mm. Calculators assume sensor has aspect ratio. First enter your application parameters in Calculator 1. This will help you determine the ideal lens focal length.

You're not likely to find a lens having the exact focal length suggested by Calculator 1. Using a common lens focal length, use Calculator 2 to determine the working distance necessary to get your desired field of view.

Or, use Calculator 3 to determine the field of view resulting from a fixed working distance. Lenses having focal lengths of 6, 8, 12, 16, 25, 35 and 50 mm are commonly available. Using a shorter focal length lens decreases your working distance and therefore captures more light, but the resulting image will be more distorted.

A 16mm lens is often a good compromise. Keep in mind that a smaller sensor size will increase the working distance. Calculators assume field of view width is in direction of the camera sensor's width.

If your field of view's height is greater than it's width, consider rotating the camera 90 degress.Looking for a list of projectors that meet your throw distance and screen size needs? Find Projectors. A projector's distance from the lens to the screen surface is called the Throw Distance. The throw distance and the size of the image it produces on the screen are proportional to each other based on the optics of the lens. As you increase the distance between the projector lens and the screen the image will also increase.

A projector's distance from a screen and the size of the image it produces are proportional to each other based on the optics of the lens. As you increase the distance between the projector and a screen the image will also increase. If your projector has a zoom lens, the lens can be adjusted to change the size of the screen image without changing the distance of the projector.

Since each projector lens is different, an online projection calculator tool will help you calculate the size of an image on a screen relative to how far the projector is placed from screen. So for example, the most common projector throw ratio is 2. So if I'm using a projector with a throw ratio of 2. So the throw ratio is a simple formula that let's you easily compute throw distance or image width given that you know one of these measurements.

A projector zoom lens will have two different throw ratios, one for the minimum zoom setting and one for the maximum zoom setting. A short throw projector is a projector with a lens that has a throw ratio of 0. These projectors are ideal for rear screen applications where the area behind the screen is limited, or for a wall mounted application where the projector will be mounted within 1 or 2 feet from the screen.

The goal of these projectors is to produce as large of an image within the shortest amount of space between the projector and the screen. Find a Projector Login. Classroom Interactive Portable. Find a projector based on your desired features and specs. Throw Calculator.

Read it and you'll become a truly story teller, I promise:. Depth of Field: The Definitve Guide. In the calculator, just introduce your camera type sensor sizeaperture, focus distance, focal length the real one! This calculator is also available in PhotoPills appextended with an augmented reality view to help you visualize where to focus. Both classic and advanced calculators include an inverse mode DoF to settings.

Just copy the following lines and paste them within the code of your website, right in the place where you want to embed it:. When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance out to infinity will be acceptably sharp. Hyperfocal near limit: The distance between the camera and the first element that is considered to be acceptably sharp when focusing at the hyperfocal distance.

Depth of field DOF : The distance between the farthest and nearest points which are in acceptable focus. This can also be identified as the zone of acceptable sharpness in front of and behind the subject to which the lens is focused on.

In an effort to guide your decision, we have created this handy CCTV lens calculator and view simulator. By adjusting the parameters below you can visualize the effects of different lens focal lengths at various distances to a given scene. Contextual help for the parameters is available by hovering the circular help icons.

Simulator Mode. Calculator Mode. Distance from Target: feet. Lens Focal Length: mm. Disclaimer: The images shown are for the purpose of simulation only, actual results may vary.

Viewable Dimensions: X feet. Did you find this useful? Please share it! Simulator Mode allows you to choose from several different scenarios and visualize the effects of various lenses at a fixed distance.

This mode limits the parameters to realistic ranges for a given scene. Calculator Mode allows you to input arbitrary values for the parameters, but does not allow you to visualize the scene.

The scene selection available in Simulator Mode only allows you to choose from several scenarios, to better help you visualize your lens selection. The sensor size refers to the size of the imager array. Choosing the incorrect size will have an adverse effect on the field of view calculations, so be sure and check your camera specifications for the correct size. If you are using the Lens Simulator on a product page, this value will be preset for you. This refers to the distance of the camera from the target scene you are trying to capture, measured in feet.

In Simulator Mode, the distance is fixed for each scene and cannot be changed. The focal length refers to the distance between the sensor and lens aperture, and determines how wide or narrow your angle of view is. Shorter focal lengths provide a wider angle of view, while longer focal lengths give a narrower view angle, allowing you to zoom in on distant objects. You can manually input a focal length or use the slider to the right of the monitor.

These are the dimensions, measured in feet, of the target viewable area dimensional field of view ; in other words, what you will see on your screen. The target area will be calculated based on the distance and focal length, or you can manually input your target area to find out what focal length you would need for that view.

While I'm in the City, I have no connection issues.

However, service in more remote areas are lacking, such as the Adirondacks. No problems during turnover or since we signed up. Any you cannot beat the prices and flexibility. The online interface just works. If you have a Sprint phone and a Sprint SIM, just bring it over. Activation happens in under a minute. The network is as good as the postpaid Sprint network. I use this for a backup phone. Make sure you use your phone at least once in 3 months, leave it on airplane mode and on wifi otherwise and you have a backup phone that you can turn on and use in an emergency.

This has been a great cell phone service and very affordable for my family. My two sons are in college and they have Tello, so with that, thank you for the awesome service and for taking care of us!!!. Their customer service is outstanding, if you ever have to call them a real person answers the phone and makes sure you are satisfied before you hang up. Love love love this company My phone recently suffered water damage, so I bought a new one and tried to switch service over.

The website said I needed a new SIM card, but I didn't believe it because both phones take nano Sprint SIMs. I contacted support via chat, and they were able to explain not only that the website was correct, but that different model phones require different SKUs of Sprint SIM card to operate on the Sprint network. Support was very fast and polite, and the prices can't be beaten for a light cell phone user like me.

I highly recommend this company.
