Feasa Optical Heads
Feasa OH Series Optical Measuring Head
Feasa Optical Measuring Heads Model OH: OH3, OH5, OH10,,, are special sockets that improve the stability of intensity measurement.
The Feasa Photometer is designed to ensure stability when testing LED intensity. The compact and rugged design provides consistent and repeatable measurements with intensity variation <10% when placing LEDs 1mm apart. The photometer solves the following problems: LED placement compensation, Repeatable intensity measurements, Reduced sensitivity to ambient light
The typical distance between the LED under test and the Photometer Head is 3mm to 5mm but can vary significantly depending on the application.




Feasa Optical Heads are special receptacles that improve the stability of intensity measurements.
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
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.
