We're interested in making sure you're happy with your purchase. Some models are available for a 30-day evaluation. The return of cameras is subject to factory discretion. Any cameras approved for return must be in new condition and in their original packaging. Returns will be subject to a restocking fee.
All returns must be pre-authorized by Machine Vision Store and shipped with freight pre-paid. Please contact us to request authorization and instructions. The item's serial number and associated sales order number will be needed.

This GigE Vision Ethernet camera has two trigger inputs plus an optically-isolated input. There are four outputs. There is also an RS232 input (RXD) and output (TXD). Inputs use Schmitt triggers for better noise immunity. Both inputs and outputs support discrete 24 VDC.

The following graphic illustrates how changing these factors: aperture, focal length and the distance from the subject affect the depth of field.

Distance to subject refers to the length between the camera and the focus of the image. The closer the camera is to the subject it is focusing on, the narrower the depth of field will be. Inversely, the farther away the subject is from the camera, the wider the depth of field will be.

The aperture is the opening created by a set of overlapping metal blades, known as the diaphragm, inside a photographic lens. This opening controls the amount of light coming through the lens. The wider the aperture, the less depth of field you capture. The smaller the aperture, the deeper the depth of field.

Depth of field (DoF) is the area between the nearest and farthest points from the camera that are acceptably sharp in an image. A deep DoF means all or most of your photo will be in focus, including the foreground, subject and background. Use a deep DoF in group photos, landscape shots and when elements in the background or foreground add to the message the photo is attempting to communicate. A shallow DoF means more narrow range will be acceptably sharp in the image. Shallow DoF is good to use when you want to isolate your subject from their surroundings, such as in a portrait or when elements in the background or foreground may be distracting.
In this image you can see how a shallow depth of field keeps the focus on the action. Photo by Samuel King In this image you can see how a shallow depth of field keeps the focus on the action. Download Image Share Image: X Facebook Email Photo by: Samuel King VIRIN: 170908-F-OC707-0517C

SVS-Vistek calls their EXO series cameras “the integrator’s camera,” and they do so with good reason. Most EXO cameras are built on Sony IMX Pregius sensors offering excellent dynamic range and efficiency with a high signal-to-noise ratio. These cameras deliver all the imaging control you would expect, plus a surprising amount of I/O functionality.
Built on the Sony Polarsens IMX250MZR sensor, the exo250ZGE camera detects the polarization of light. A four-directional polarization filter using nano-wires is overlaid directly on top of the pixel array and beneath the micro lenses. This filter consists of repeated 2 x 2 patterns of grid polarizers with four different angles: 0, 45, 135 and 90 degrees. Each polarizer filters the incoming light so that only the polarization components perpendicular to the grid orientation can pass through and be detected by the underlying photo-diode. A four-direction polarization image can be captured in a single shot.
You can affect the depth of field by changing the following factors: aperture, the focal length and the distance from the subject.

The EXO series cameras have a precision-machined 50 x 50 mm IP40 aluminum body. The unibody housing ensures excellent temperature distribution, enabling today’s image sensors to run cooler. The rigid lens mount keeps lenses properly positioned to maintain sharp focus. There are mounting holes on five faces of the housing, plus a standard 1/4-20 tap on the bottom for attaching a tripod.
Being GigE Vision and Genicam compliant, most machine vision software platforms can easily communicate with EXO cameras. And, for those that prefer to develop a custom application, there is a free SDK.

The manufacturer will repair or replace defective cameras within two years of factory shipment. For further information, please refer to the manufacturer's website.
The focal length of the lens determines the image magnification. The wider the lens, the shorter the focal length. This allows you to capture a wider depth of field. The longer or more zoomed in the camera lens, the less depth of field you capture.
The camera’s inputs offer unusual functionality. They can be configured to debounce inputs, control timing of camera operations and output signals, and control four independent pulse (PWM) generators. Timing functions can be programmed with a resolution of 15 ns. A pulse divider lets you take an action on every nth signal, where n is a value between 1 and 15. Logic gates (AND, NAND, OR, NOR) combine signals to make decisions.
A built-in LED driver enables control of external lights. The driver delivers up to 3 amps for 40 ms, or 0.3 amps continuously. High-frequency PWM functionality enables the camera to control light intensity. Most EXO models support up to four independent lights.
