850 nm single-mode VCSELs are the perfect choice for demanding sensor applications due to their improved optical characteristics. Higher-order longitudinal and transversal modes are suppressed by the innovative chip design; at the same time, the polarization is linearly stable.

Condition:TO P = 20°C, IO P = 10.0 mA unless otherwise stated (TO P = chip backside temperature, controlled by the TEC)
