Product Description

Introduction

BS-2093B Inverted Biological Microscope is a high level microscope which is specially designed for medical and health units, universities, research institutes to observe cultured living cells. With an innovative infinite optical system and ergonomic design, it has excellent optical performance and easy to operate features. This inverted biological microscope makes your work enjoyable. Digital cameras can be added to the trinocular head to take photos, videos and make measurement.

Feature

1. Excellent infinite optical system, Wide field eyepiece, view field up to Φ22mm, perfect for cell observation and culture.
2. Brand-new design for life science research.
3. More objectives can be installed on the large diameter quintuple nosepiece, easier to change objective.
4. 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.
5. Light distribution (both): 100 : 0 (100% for eyepiece); 80 : 20 (80% for trinocular head and 20% for eyepiece).

6. Automatic infrared induction for power on-off. Power off upon user leaving 10 minutes, and power on upon user approaching.
7. Special light port for SLR digital camera, 7°inclined up to be more convenient to observe the image of the DSLR camera.
8. 12V/50W Kohler illumination makes the field more even and brighter.
9. 4-hole rotating disc phase contrast condenser as standard to change bright field and phase contrast easily.
10. Culture Dish Holders.
13. Knob of X-Y mechanical stage can be changed by left or right.
14. Infinite plan 4X phase contrast objective is available.
