NUV objective lens
High NA infinite conjugate objective lens for YAG laser third harmonic (355nm) or femtosecond laser (770790nm) processing
Product details
YAGLaser's3Subharmonic（355nm）Or femtosecond laser（770~790nm）High processing requirementsNAInfinite conjugate objective lens.
Due to the correction of visible spectral aberration in the design, the machined surface can be observed coaxially with the laser beam.
◆ Working distance of objective lens（WD）The length and curvature of the field have also been corrected, and natural and clear observation images can be obtained at the edge of the field of view.
◆ It can be used for coaxial observation systems or laser guided optical systems, and is an infinitely far corrected objective lens.
◆ It can also be used for observation of near ultraviolet and infrared light.
This mirror can also be used for visible light（532nm）Pulse laser.
