MW 50D Digital

Led Slit lamp


New MW 50D Slit Lamp: a towards revolution in super-wide magnification fine optics. Available in clinical and digital versions.

Ultra wide magnification range

  • A newly-developed microscope with drum-type 5-step zoom and fine optics.
  • A new optical system enables bright imaging even at 50x magnification.
  • Drum-type zooming makes it easier to adjust the magnification within the wider range of 5x to 50x.
  • All optics for observation are multi-coated to enable clear and high-resolution images, resulting in extremely
    high quality optics.

High field of view eyepiece

  • Wide field of view observation is possible even when wearing eyeglasses. Eyepieces can be fixed to the microscope tube to reduce gaps.

15° tilting tube (option)

  • 15° tilting angle allows observation at a natural posture for taller users. It is also possible to reduce the angle for shorter users.

Convergence type eyepiece tube

  • The eyepiece tube converges at 8° from parallel optics for easy fusion, making more efficient and natural observation possible.

High operability

  • A new plate is employed for stress-free smooth focus adjustment.

Bright colors

  • A LED light source, whose wavelength is much closer to a halogen lamp, has been employed to give the slit lamp a bright, natural color. This eliminates the need for a filter to remove the common “bluish LED light” problem.

Digital camera

  • 5M pixel wide dynamic range CMOS camera that reproduces natural color
  • Captures images at a high frame rate of 30 fps for smooth movies
