FAQ - Frequently Asked Questions
- Sample too thick / unsuitable: Use thin samples or fixed smears.
- No cover glass or incorrect thickness: Objectives are optimized for cover glasses.
- Condenser incorrectly adjusted: Do not open the diaphragm too far – otherwise contrast will be low.
- Magnification too high: Rule of thumb: maximum 1000 × objective aperture. Example: With a 40x objective with aperture 0.65, the limit is about 650x.
Product information "BRESSER Science ETD-201 8-50x Trino Zoom Stereo-Microscope"
The extra wide foot with stage and exceptionally tall height range permit observations of large objects. The integrated reflected- and transmitted-light illumination can be used in combination and is dimmable. The angle of incidence can be user-friendly adjusted and locked in position. A continuous range of magnification from 8x to 50x is possible with the exchangeable wide field eyepieces (WF 10x) and the 6.25-times stereo zoom objective lens (0,8x-5x).
The interpupillary distance and dioptre compensation can be adjusted individually. The trinocular microscope head is rotatable (360°) and comes with two 45° inclined eyepiece tubes and a separate camera tube for the attachment of a c-mount camera or MikroCam.
