LB-617 Advanced Trinocular Metallurgical Microscope

LB-617 Advanced Trinocular Metallurgical Microscope is developed for research with a number of pioneering design in appearance and functions, with wide field of view, high definition and bright/dark field semi-apochromatic metallurgical objectives, they are born to provide a perfect detection solution and develop a new pattern of industrial field. 

Labomed, Inc. is certified by ISO 9001-2013, has CE Conformity and is FDA Licensed.

Features

  • High eye point wide field plan eyepiece. The eyepiece field of view has been upgraded from traditional 22mm to 25mm and 26.5mm, providing a more flat field of view and improving the working efficiency. With wider diopter adjustment range and foldable rubber eye guard.

  • Viewing head with multi-splitting ratio.
    The viewing head is designed with multiple options for splitting ratio.
    (1) Trinocular head with erected image is standard, splitting ratio Binocular:Trinocular=100:0 or 0:100. The moving direction of samples is the same as observed.
    (2) Trinocular head with inverted image is optional, splitting ratio Binocular: Trinocular=100:0 or 20:80 or 0:100. Except for concentrating 100% light to eyepiece tube or camera tube, there is another option with 20% light to eyepiece tube and 80% to camera tube, so that the eyepiece observation and image output can be available at the same time.

  • Polarization system.
    The polarizer and analyzer in the polarization system contributes to eliminate the stray light in semiconductor and PCB detection, so that an image with clear detail is achievable. You have two options: a fixed analyzer and a rotatable analyzer. The sample can be observed at different polarizing angles with 360° rotatable analyzer. Besides, this polarization system can be upgraded to Nomarski differential interference contrast system after installing a newly developed DIC attachment.

  • Nomarski differential interference contrast system(DIC).
    The tiny rough edges on the surface which can not be found in the bright field are able to be detected by using U-DICR attachment to create high contrast stereo relievo effect. It is widely used for testing the electric-conductive particles of LCD and surface scratches of the precision disk.
    DIC
  • Linkage between the neutral density filter and the switch for BF & DF.
    The lever in front of illuminator is used to switch between bright field and dark field, and it is in tandem with a neutral density filter (ND50). When you switch from DF to BF, the built-in ND50 filter takes the role to reduce the light intensity. It is more scientific and more comfortable.

  • Multiple choice for Nosepiece.
    The new nosepiece reduces the angle between the optical axis and the rotating axis to 15°, improving the accuracy of the centering and parfocality, and the appearance is more compact.
