Inspection Material Properties<\/h2>\n<p>The first consideration, when selecting\u00a0<a href=\"https:\/\/www.prophotonix.com\/applications\/machine-vision-lighting\/\"><u data-redactor-tag=\"u\"><strong data-redactor-tag=\"strong\">machine vision lighting<\/strong><\/u><\/a>, should always be the material under inspection. Determining the transmission or reflective properties of your material is the first step in identifying the correct wavelength for your application.<\/p>\n<h2>2. Environment<\/h2>\n<p>Excessive, low light or variable lighting conditions can affect the performance of your vision system. With these environmental conditions, it may be best to use a non-visible IR wavelength to achieve the optimum performance for your application.<\/p>\n<h2>3. Camera Sensitivity<\/h2>\n<p>Camera sensitivity in the IR region varies significantly and will depend on the type of camera you are using. The key to success in many\u00a0<a href=\"https:\/\/www.prophotonix.com\/applications\/machine-vision-lighting\/ir-machine-vision-lighting\/\"><u data-redactor-tag=\"u\"><strong data-redactor-tag=\"strong\">infrared machine vision lighting<\/strong><\/u><\/a>\u00a0applications is to balance the sensitivity of the camera with the transmissive or reflective properties of the material under inspection and LED efficiency.<\/p>\n<h2>4. Wavelength<\/h2>\n<p>Although IR LEDs have been around since the 1960s, LED efficiencies still vary between 10% and 35%. To select the optimum\u00a0<a href=\"https:\/\/www.prophotonix.com\/blog\/wavelength-machine-vision-lighting\/\"><u data-redactor-tag=\"u\"><strong data-redactor-tag=\"strong\">wavelength<\/strong><\/u><\/a>\u00a0for your application, you must manage the trade-offs between LED efficiency, camera sensitivity &amp; other factors.<\/p>\n<h2>5. Safety<\/h2>\n<p>Safety is a key consideration in some IR applications. In\u00a0<a href=\"https:\/\/www.prophotonix.com\/blog\/ir-illuminator-ir-illuminator-for-anpr-systems\/\"><u data-redactor-tag=\"u\"><strong data-redactor-tag=\"strong\">ANPR\/ ALPR applications<\/strong><\/u><\/a>, the key safety consideration is eye safety. In this application, the trade-off is to select a\u00a0<a href=\"https:\/\/www.prophotonix.com\/blog\/wavelength-machine-vision-lighting\/\"><u data-redactor-tag=\"u\"><strong data-redactor-tag=\"strong\">wavelength<\/strong><\/u><\/a>\u00a0that optimizes camera sensitivity, but takes into account the sensitivity of the human eye, thus ensuring that road users are not impacted by the ANPR system. Intensity will always need to be managed to ensure the safety of users.<\/p>\n<h2>6. Cost Considerations<\/h2>\n<p>All of the above are technical considerations, but as any project manager knows, cost is also a consideration. Your IR solution should offer good value for money. To ensure this, select a manufacturer with the ability to manage low or high volume manufacturing.<\/p>\n<h2>7. Form factor<\/h2>\n<p>All too often, form factor is not considered until too late in the design of the <strong><a href=\"https:\/\/www.prophotonix.com\/applications\/machine-vision-lighting\/\">machine vision lighting<\/a><\/strong> system. Although we have listed this last, it is a key consideration when designing a machine vision system for your application. A light that achieves the required intensity at the optimum wavelength is of little use, if it does not fit properly into your system.
