Distance from lens reference plane to surface, Z Sensor Lens Navigation Surface Lens to Surface 2.40 Optical/Electrical Characteristics (at Tc = 5°C to 45°C): VCSEL Die Source Marking V = A,V V = C Parameter Symbol Min Typ Max Min Typ Max Units Notes Peak Wavelength λ 832 865 832 865 nm Maximum Radiant Power LOPmax 4.5 4.0 mW Maximum output power under any condition. This is not a recommended operating condition and does not meet eye safety requirements.

VCSELs are sorted into bins as specified in the power adjustment procedure. Appropriate binning register data values are used in the application circuit to achieve the target output power. The VCSEL binning is marked on the integrated molded lead-frame DIP sensor package. 2. When driven with current or temperature range greater than specified in the power adjustment procedure section, eye safety limits may be exceeded. The VCSEL should then be treated as a Class IIIb laser and as a potential eye hazard. 3. Over driving beyond LOPmax limit will cause the VSCEL to enter into on unstable region. Any LOP reference point in the laser power calibration process. |
