Max Unit Optical Output Power CW Po - - 20 mW Peak Wavelength Po=20mW λp 390 - 400 nm Threshold Current CW Ith - 43 - mA Operating Current Po=20mW Iop - 53 - mA Slope Efficiency CW η - 2.0 - W/A Operating Voltage Po=20mW Vop - 4.0 - V θ// 7 - 12 deg. Beam Divergence*2 Po=20mW θ⊥ 15 - 23 deg. ∆θ// -2.0 - 2.0 deg. Emission Point Accuracy Angle Po=20mW ∆θ⊥ -2.5 - 2.5 deg. Monitor Current*3 Po=20mW Im - - 1 mA *1 There is some range in ambient temperature. *2 Full angle at 50% from peak intensity *3 Monitor Current is short time power reference purpose only. Not guaranteed for accuracy. This value must be affected intensely by feedback from composing optics. All figures in this specification are measured by Nichia's method and may contain measurement deviations. Diffractive feedback efficiency to the Laser diode must be limited less than 30 % under the External cavity configuration. This model is Test Sample for evaluation or design purpose only. Life time is not guaranteed. The above specifications are for reference purpose only and subjected to change without prior notice. Safety of Laser light Laser Light can damege the human eyes and skin. Do not expose the eye or skin to any laser light directly and/or through optical lens. When handling the LDs, wear appropriate safety glasses to prevent laser light, even any reflections from entering to the eye. Focused laser beam through optical instruments will increase the chance of eye hazard. These LDs are classified in Class 4 of IEC60825-1 and 21 CFR Part 1040.10 Safety Standards. It is absolutely necessary to take overall safety measures against User's modules, equipment and systems into which Nichia LDs are incorporated and/or integrated.
