Near IR Objective (M iPlan Apo NIR Series)

Infinity correct design objective lens with high N.A. for laser material processing with femtosecond laser and near infrared laser.
Normal brightfield observation in visible wavelength range is also available.

  • Infinity correct design,
  • Compensation design of wavelength from visible range to near infrared range.
    NIR5,NIR10: 400 nm – 1064 nm.
    NIR HD 20,NIR HD 50: 450 nm – 790 nm.
    NIR 50: 450 nm – 1340 nm.
  • High resolution desigh,
  • Parfocal distance: 95 mm,
  • Designed of compensation design for 3 kinds of high magnification objective lens
    for thickness of 1.8 mm or 0.7 mm crystal liquido, recommendable of bright field
    observation or laser material processing through crystal liquid.
