Feasa Optical Head – Data Sheet The Feasa Optical Heads have been designed to ensure stability when testing the intensity of LEDs. The robust and compact design delivers consistent and repeatable readings with a <10% intensity change over a 1mm placement of the LED. The Optical Head addresses the following issues: • Compensation for LED Placement • Repeatable Intensity Readings • Reduced sensitivity to ambient light Optical Head Specification & Ordering Information These Optical Heads (OH) have a Diameter of 2.54mm and are suitable for Led centre to centre distance of 2.8mm: They are used with 1mm Plastic Optical Fiber (POF) which needs to be glued in place.
