Presenting the advanced optical instrument designed for precise slide illumination and enhanced optical performance. This system is perfect for laboratory settings where accurate slide viewing and flexible movement are essential. Features include:

- Movement of Optical Tubes:
  - Horizontal Movement: Adduction of 50° and abduction of -40° for wide lateral adjustments.
  - Vertical Movement: Hyper 30° and hypo 30° for fine vertical positioning.
  - Torsional Movement: Incyclo 20° and excyclo 20° for enhanced rotational flexibility, allowing precise alignment of optical components.

- Slide Illumination:
  - Controlled by a rheostat, each slide is illuminated by a 6V lamp. After-image illumination is also supported, ensuring clear visibility of slide content.
  
- Auto Flashing:
  - Auto flashing functionality allows for simultaneous or alternating flashing of slide illumination in rapid and variable modes, providing flexibility in visual analysis.

- Mode & Mode Selection:
  - Five selectable modes of slide illumination: Normal, Flashing Right, Flashing Left, Flashing Right & Left, and Auto Flashing. These modes are easily controlled with a single selector knob for quick adjustments.
