Features

1.Wide field of view

Excellent infinite optical system, Wide field eyepiece, view field up to Φ22mm, more comfortable for observation.

2.Better nosepiece

More objectives can be installed on the large diameter quintuple nosepiece, easier to change objective.

3.Viewing head with two splitting ratios

Light distribution (both): 100:0 (100% for eyepiece) or 80:20 (80% for trinocular head and 20% for eyepiece).

4.Camera ports

Both light ports for microscope digital camera and DSLR photography camera, available for observing with microscope digital camera and DSLR photography camera at the same time.

Special light port for SLR digital camera, 7°inclined up to be more convenient to observe the image of the DSLR camera.

5.ECO function

Automatic infrared induction for power on-off. Power off upon user leaving 10 minutes, and power on upon user approaching.

6.Kohler illumination

12V/50W Kohler illumination makes the field more even and brighter.

7.4-hole rotating disc phase contrast condenser

4-hole rotating disc phase contrast condenser as standard to change bright field and phase contrast easily.

8.LED Epi fluorescent unit

Newly designed BFL2LED (5W LED lamp, B/G fluorescent filter) & BFL3LED (5W LED lamp, UV/B/G fluorescent filter) LED fluorescent unit can provide higher intensity and get clear images.

9.Convenient for both hands

The knob of X-Y mechanical stage can be changed by left or right.
