COLO.SCIENCE – STEREO MICROSCOPY / INSPECTION & DOCUMENTATION
Why STEG45 is a practical stereo microscope choice
STEG45 is a Greenough zoom stereo microscope designed for clear 3D viewing with comfortable ergonomics. It delivers a practical magnification range of 7×–45× using a continuous 0.7×–4.5× zoom objective and wide field optics.
With LED reflected illumination (4.5W, 0–100% dimmer) and a stable boom stand, it fits inspection work, education labs and routine QC where positioning above the sample matters.
Key features (short)
- Greenough optical system; anti-fungus & anti-reflection treated optics.
- HSWF 10×/Ø23 mm eyepieces (high eye point), field of view up to 23 mm.
- Continuous zoom objective 0.7×–4.5× (6.4:1 zoom factor).
- Working distance 110 mm; maximum sample height 130 mm.
- LED incident (reflected) light 4.5W with dimmer (0–100%).
Where it fits best
- Biology: dissection, entomology, botany.
- Electronics: PCB inspection, micro soldering.
- Industrial: quality control, jewellery appraisal.
- Education: student labs and trainings.
PRACTICAL USE & CHECKLISTS
Daily setup checklist (fast)
Start at low magnification, set IPD (52–76 mm) and diopter adjustments. Position the sample, then raise intensity gradually using the LED dimmer for glare-free viewing.
For fine control, use tension/torque regulation on the coarse adjustment to match your hand feel and prevent drift during inspection.
COLO.Science & equipment
COLO.Science supports selection, configuration and accessory matching (ring light, camera options, ergonomic head) to fit your application.
If you need imaging, the trinocular head offers a Ø30 mm photo port with fixed 50:50 beam splitter (per PDF).
