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

OH-1: This can be used when LEDs are located as close as 3.55mm centre to centre on a PCB.

OH-2: This can be used when there are fixturing height restrictions as it is only 25mm in length.

OH-3: Our standard Optical Head and is suitable for most applications with a centre to centre distance of 5mm.

OH-4: Ideal for testing 90° or side emitting LEDs.

OH-5: Is used when LEDs are as close as 4.00mm centre to centre on a PCB.

OH-6: Has a large diameter, 8.00mm and is used with large diameter LEDs. Designed for testing High Brightness LEDs and LEDs with a large diameter, particularly suitable for Daytime
Running Lights.

OH-7LT: Is designed to be used in an oven with the LED Life Tester. The temperature range of this Optical Head is -65°C to +125°C.

OH-8IR: Is designed to test the Intensity of Infrared LEDs in conjunction with the IR LED Analyser.

OH-9: All plastic components mean this Optical Head is suitable for use in RF environments.

 

 

 

 

 

 

 

 

 

 

 

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.
