Feasa光学采光头是为了保证测试LED光强度的稳定性而设计的，小巧而坚固，提供高精度和高重复性的光源采集，其解决如下问题：
The Feasa Optical Heads have been designed to ensure stability in testing the intensity of LEDs.The robust and compact design delivers consistant and repeatable readings, + 1mm with <10% Intensity change. They address the following issues:
•光纤固定困难Compensation for LED Placement
•重复精度不高Repeatable Intensity Readings
•环境光的干扰，导致光源采集的灵敏度下降Reduced sensitivity to ambient light
配套光学采光头的使用Using the Optical Heads：
OH-2用于高度受限制的情况下。
OH-2is used when height is restricted.
OH-3用于大多数情况下。
OH-3is suitable for most applications.
OH-4用于90°弯脚或者横插LED的情况下。
OH-4is ideal for testing 90° side emitting LEDs.
OH-5用于元器件密集的PCB板或者相邻LED间距小的情况下。
OH-5is most suitable when LEDs are close together on Printed Circuit Boards.
OH-6用于直径较大的LED和检测高亮LED，特别适合于环境光较亮的情况下。
OH-6has a large diameter, 8.00mm and is used with large diameter LEDs. Designed for testing High Brightness LEDs, particularly suitable for Daytime Running Lights.
OH-7LT用于LED寿命测试仪
OH-7LTis used with the LED Life Tester.
OH-8IR用于红外线LED测试仪
OH-8IRis used withe the IR LED Tester.
注：为了保证光源采集的精度，采光头与被测LED的距离尽量保持在3mm至5mm之间，可根据实际情况适当调整。
The typical gap between the LED being tested and the Optical Head is between 3mm and 5mm but may vary significantly depending on the application.
