Best is always subject to your needs.<\/p>\n<p><!--more--><\/p>\n<p>In <a title=\"our previous blog post\" href=\"https:\/\/www.adimec.com\/how-to-select-the-best-industrial-camera-step-1-identify-your-key-camera-parameters\/\" target=\"_blank\" rel=\"noopener\">our previous blog post<\/a> we talked about searching for available products and then <a title=\"narrowing down your possibilities\" href=\"http:\/\/info.adimec.com\/blogposts\/bid\/76802\/How-to-select-the-best-industrial-camera-Step-2-Preliminary-Camera-Selection\" target=\"_blank\" rel=\"noopener\">narrowing down your possibilities<\/a> to a short list of 3 to 5 camera suppliers. Even if you have consistent data from the camera manufacturers and strong recommendations, you need to determine the necessary level of certain performance parameters since there are sometimes price consequences for more stringent requirements.\u00a0 Most industrial camera manufacturers have an evaluation\/demo\/loaner program to allow you to borrow a camera and see for yourself.\u00a0 This process can require a lot of time which is why it is so important to have previously minimized the number of possibilities.<\/p>\n<p>Though the evaluation process is lengthy, it allows you to:<\/p>\n<ul>\n<li>See the actual hardware, the software, and the integration for yourself<\/li>\n<li>Verify your assumptions<\/li>\n<li>Verify the specifications provided<\/li>\n<li>Check that it will enable the measurements you want to do<\/li>\n<\/ul>\n<p>A good starting point is to simply get the camera up and running and look at the resulting image.\u00a0 You can play around with the gain settings to get a feel for defect pixels or other artifacts.<\/p>\n<p>You may want to quantify performance differences for yourself.\u00a0 The Photon Transfer Curve (PTC) characterization method can be used as a standardized test procedure to verify performance such as read noise, dark current, full well capacity, sensitivity, dynamic range, gain, and linearity.\u00a0 A curve rather than one data point can often give more insight if you know how to interpret it.\u00a0 There are several great sources on how complete a PTC calibration and calculate the camera parameters.\u00a0 The links below are some other examples:<\/p>\n<p><a href=\"http:\/\/www.couriertronics.com\/docs\/notes\/cameras_application_notes\/Photon_Transfer_Curve_Charactrization_Method.pdf\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" id=\"img-1327409767095\" style=\"height: 308px; width: 508px; display: block; margin-left: auto; margin-right: auto;\" src=\"\/\/cdn2.hubspot.net\/hub\/20421\/file-13403351-jpg\/images\/photon_transfer_curve.jpg\" alt=\"Photon transfer curve\" width=\"507\" height=\"308\" border=\"0\" \/><\/a><\/p>\n<p><em>Source of image is the document in the following link.<\/em><\/p>\n<p><a title=\"http:\/\/www.couriertronics.com\/docs\/notes\/cameras_application_notes\/Photon_Transfer_Curve_Charactrization_Method.pdf\" href=\"http:\/\/www.couriertronics.com\/docs\/notes\/cameras_application_notes\/Photon_Transfer_Curve_Charactrization_Method.pdf\" target=\"_blank\" rel=\"noopener\">http:\/\/www.couriertronics.com\/docs\/notes\/cameras_application_notes\/Photon_Transfer_Curve_Charactrization_Method.pdf<\/a><\/p>\n<p>To truly understand which camera will be best, you may need to try them directly in your system or at least in a test set-up, if possible.<\/p>\n<p>At the end of these steps, you should know what camera is the best for you.\u00a0 Of course then you still have to determine if the company offers the right support and manufacturing controls as well as consider pricing versus value.\u00a0 Or, if at the end of this, you determine that none of the existing products will meet your needs, perhaps some minor modifications will make for a perfect fit.\u00a0 Then you need to find a manufacturer with a well-matched starting product and the <a title=\"willingness and experience to tailor the camera.\" href=\"https:\/\/www.adimec.com\/\" target=\"_blank\" rel=\"noopener\">willingness and experience to tailor the camera.<\/a><\/p>\n<p>Download the whole series in 1 document!\u00a0 Click the image below &#8211; no contact information required.<\/p>\n<p><a href=\"\/\/cdn2.hubspot.net\/hub\/20421\/file-2067790967-pdf\/docs\/how-to-select-the-best-industrial-camera---final.pdf\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" id=\"img-1327571339520\" style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"\/\/cdn2.hubspot.net\/hub\/20421\/file-13402903-jpg\/images\/how_to_select_the_best_machine_vision_camera.jpg\" alt=\"how to select the best machine vision camera\" border=\"0\" \/><\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Choosing the correct industrial camera for your system from the beginning can eliminate costly redesigns or up&hellip;<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"content-type":"","_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1936","post","type-post","status-publish","format-standard","hentry","category-uncategorized","category-1","description-off"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.3 -
