- Stemi 355 LED: Integrated LED illumination.
- Stemi 355 ECO: Economical version.
- Stemi 355 ESD: Electrostatic discharge protection for sensitive components.
- Stemi 355 Mat: Microscope set with a specific stand.
- Stemi 355 Edu: Educational set.
- Stemi 355 Lab: Laboratory set.
Illumination Options
The Stemi 355 supports a variety of illumination methods to optimize sample viewing:
- LED Illumination: Available in various configurations including ring lights (segmentable and standard), double spot illuminators, and spot illuminators. LED illumination offers consistent brightness, long lifespan, and energy efficiency.
- Cold Light Sources: Including CL 1500 HAL (Halogen) and CL 6000 LED, providing flexible and powerful illumination.
- Transillumination: Bases with glass plates, plastic plates, and diaphragm inserts are available for transmitted light applications.
- Accessories: Diffusers, polarization filters, and focusing attachments are available to modify and enhance illumination.
Stands and Stages
A range of stands and stages are offered to accommodate different working environments and sample handling requirements:
- Stands: Including Stand C (with glass and plastic plates), Stand L LED, Stand U (with articulated suspension arm), Stand SDA (twin boom), and Boom Stand B.
- Stages: Mechanical stages, gliding stages, ball-and-socket stages, and rotating polarization stages are available.
- Accessories: Mounting frames, insert plates, stage clips, and adapters facilitate sample positioning and stability.
Camera and Imaging
The Stemi 355 is compatible with various cameras for digital imaging and documentation:
- ZEISS Axiocam: High-resolution microscope cameras.
