Specifications

Features

nnnn

Compatible with three wavelengths of YAG laser (266 nm, 355 nm,

nnnn

and 532 nm), with a long working distance.

nnnn

• Outstanding compensation for chromatic aberration with visible

nnnn

light (546 nm and 532 nm wavelengths) and ultraviolet light (266

nnnn

nm and 355 nm wavelengths)*

nnnn

• Uses high transmittance glass and high efficiency antireflective

nnnn

coating. High transmittance from the visible range to the ultraviolet

nnnn

range.

nnnn

Combined with the Nikon NLB-4 optical lens barrel for lasers, these

nnnn

objective lenses enable precise and fine micromachining and

nnnn

observation.

nnnn

• Non-cemented lens design offers superior laser durability.

nnnn

* Only UV5xA compensate continuously from 266 nm to C (656.3 nm)
