New telephoto lenses for process observation


During process observation within VIS spectrum, chromatical aberrations occur caused by the difference in laser and observation wavelength.

While lateral shift can't be affected with the observation lens, the difference in working distances, caused by the chromatic focus shift, can be compensated by focal lens adjustment.

Our new telephoto lenses S5VPJ0303 and S5VPJ0305 includes a tunable liquid lens and offer high speed adjustment of focal length to compensate the working distance deviation.
