Usage Features
The manual provides detailed procedures for basic operations and various observation methods.
- Turning ON the main switch: Instructions vary depending on the control box (BX3M-CB or U-CBS) and specific lamp housings (mercury, light source, halogen, LED).
- Selecting observation method: This involves using selector knobs or turrets on illuminators like BX3M-RLAS-S, BX3M-KMA-S, BX3M-RLA-S, or BX3M-URAS-S to choose between brightfield, darkfield, DIC, polarization, or fluorescence.
- Changing light path: A light path selection lever on trinocular tubes allows switching between eyepiece and camera light paths (e.g., 100% eyepiece, 20% eyepiece/80% camera, 100% camera).
- Placing a sample: Samples are placed on the stage plate, secured with a specimen holder.
- Selecting objective: Objectives are selected by turning the nosepiece. For motorized nosepieces, a hand switch (BX3M-HSRE) is used.
- Focusing: The BXFM frame moves vertically using coarse and fine focusing knobs. The tension of the coarse focusing knob is adjustable.
