Description
OBL 137 transmitted light microscope, trinocular, incl. eyecups and dust cover
Lab Line. Flexible and versatile transmitted light microscope (bright-field) with infinitely corrected optics. Specially designed for laboratories that work with translucent, low-contrast, challenging specimens (e.g. living mammalian cells, bacteria, tissues).
- The infinity corrected optics ensure top-class image quality
- The 4-slot lens revolver is fully equipped with four high-quality, infinitely corrected E-PLAN lenses (4x/10x/40x/100x) with improved edge definition
- The 1.25 Abbe condenser with aperture cover, with its height-adjustable focus and fixed precentring, and the field diaphragm enable easier Köhler illumination and thereby provide simple and optimal illumination of the specimen, with no negative flare effects
- The mechanical cross table ensures fast working and positioning of the specimen. It features a coaxial coarse and fine focus drive fitted on both sides for adjusting the height and focussing on the specimen
- With strong, infinitely dimmable 3 W LED transmitted light illumination
Optional accessories (please order separately):
- Dark field condenser to increase contrast of small, unstained structures
- 100x lens (planachromatic, spring) with water immersion
With trinocular head for mounting a microscope camera on the phototube using C-mount adapter. Please order C-mount adapter separately.
Delivery incl. colour filter (blue, integrated), eyecups and dust cover.
