BMI-5B research level inverted biological microscope

BMI-5B

  1. Seidentopf head with Bertran lens, when Bertran lens in, users can check the optical pupil, work as centering telescope.
  2. Retroverted light frame making sure users has more working space, easy to change the sample.
  3. Turret type condenser LWD with six positions, inner fixed bright field phase contrast, DIC.
  4. Three layer mechanical stage, moving range 130 x 85 mm, flexible knob, can fix different small size stage on the top for different appkication.
  5. Turret type fluorescent cube holder easy to change.
  6. N-IPLAN PH PLAN Semi-Apo lens 4x, 10x, 20x, 40x.
  7. Middle zoom lens 1x; 1,5x.
  8. Both side optical output port, easy to upgrade for more applications such as laser confocal microscope.
  9. 96 well plates Terasaki holder (φ38mm and φ54mm)
