Optical Head to Test LED’s

The Feasa Optical Head has been designed to reduce the placement sensitivity of LEDs when using the Feasa LED Analyser. The Feasa Optical Optical Head has the ability to capture LED light and focus it onto the Optical Fiber. The position of the LED relative to the fiber can vary and have negligible effect on the relative intensity measured. A single Feasa Optical Head is required for each LED to be tested and up to 20 heads can be fitted to a LED Analyser.

Product NumberProduct Uses
OH-1This can be used when LEDs are located as close as 3.55mm centre to centre on a PCB
OH-2SThis can be used when there are fixturing height restrictions as it is only 30mm in length
OH-3Our standard Optical Head and is suitable for most applications with a centre to centre distance of 5mm.
OH-4Ideal for testing 90° or side emitting LEDs.
OH-5Is used when LEDs are as close as 4.00mm centre to centre on a PCB
OH-6Has 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.
