   Parameters	Symbol	Min.	Typ.	Max.	Unit	Test Condition
   Viewing Angle [1]	2θ1/2	---	120	--	Deg	IF=350mA
   Forward Voltage [2]	VF	1.6	---	2.2	V	IF=350mA
   Reverse Current	IR	---	---	10	µA	VR=5V
   Peak Emission Wavelength	λp	---	730	---	nm	IF=350mA
   Dominant Wavelength	λd	----	730	----	nm	IF =350mA
   Spectrum Radiation Bandwidth	Δλ	---	10	---	nm	IF=350mA
   Power Intensity	Pv	160	---	240	mw	IF=350mA

    

   Notes:

6. 2θ1/2 is the off axis angle from lamp centerline where the luminous intensity is 1/2 of the peak value.
7. Forward Voltage measurement tolerance : ±0.1V

8.  

    

   Notes:

   1. Luminous Radiant is measured with a light sensor and filter combination that approximates the CIE eye-response curve.

   2. θ_1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
