SPZ-Bi Stereo Microscope
Professional Stereozoom Binocular Microscope
The SUSWOX SPZ-Bi is a professional stereozoom binocular microscope designed to combine the versatility of a stereozoom system with the stability and ergonomics of a laboratory microscope. It is engineered for routine laboratory observation, inspection, dissection, industrial quality control, precision assembly, research and digital microscopy applications.
The SPZ-Bi uses a Greenough stereoscopic optical system with a continuous 8X–50X magnification range using the standard 10X eyepieces. Its 1:6.3 zoom ratio, 115 mm standard working distance and three-dimensional stereoscopic imaging provide excellent depth perception while leaving sufficient space for specimen manipulation.
The microscope incorporates a large stable track stand, lateral zoom control, specimen clip and integrated LED incident/transmitted illumination. Its modular design allows the system to be expanded with auxiliary objectives, higher-magnification eyepieces, ring illumination and digital imaging accessories.

Where it earns its place
Built for precision inspection
The stereo microscope sits at the intersection of versatility and clarity: more depth perception and working distance than a compound scope, without the cost of a dedicated research instrument.
Electronics & PCB Inspection
PCB assembly, solder joints, connectors, micro-components and electronic assemblies. The continuous zoom and true 3D stereo view provide depth perception for precise inspection and rework.
Industrial Quality Control
Ideal for component inspection, surface defects, machining quality and dimensional assessment. The rugged metal body, precision focusing and great working distance support demanding inspection environments.
Jewellery & Watchmaking
Examine gemstones, jewellery settings, watch components and fine mechanical parts with excellent depth perception. The long working distance provides comfortable space for handling and precision assembly.
Medical Device Inspection
Suitable for inspection of small medical components, instruments, assemblies and precision-manufactured parts. High-contrast stereo imaging helps reveal fine surface details and manufacturing defects.
Biological Research & Dissection
Useful for specimen examination, dissection, entomology, botany and other applications requiring a three-dimensional view. The binocular Greenough optical system provides natural depth perception during manipulation.
Digital Documentation & Training
Camera-ready for digital imaging, screen sharing, documentation and inspection records. Optional C-mount camera compatibility makes the stereo microscope suitable for training, demonstrations and collaborative analysis.
Before you order
Questions buyers actually
ask
Q1 What is the maximum magnification of the CXL Bi?
1000×. The WF10X eyepieces multiply with the 100X oil immersion objective, giving 40×, 100×, 400× and 1000× across the four positions on the nosepiece. Beyond 1000× you gain no additional detail with this optical system — you are only enlarging an image the numerical aperture has already limited.
Q2 Do I need immersion oil, and can I skip it?
You need it for the 100X objective. Without oil filling the gap between the coverslip and the front lens, light bends away at the glass–air boundary and the effective N.A. drops well below 1.25 — the image goes dim and soft. A vial is included in the box. Wipe the objective with lens tissue after each session.
Q3 What is the difference between semi-plan and plan achromatic objectives?
Semi-plan objectives give a flat, sharp image across roughly 80% of the field, with slight softening at the extreme edge. Plan objectives correct the full field but cost significantly more. For routine screening and teaching, semi-plan is the practical choice; for photomicrography where edge-to-edge sharpness is published, ask us about the plan upgrade.
Q4 LED or halogen — which should I specify?
LED for almost every lab. It runs at 50,000 hours against roughly 1,000 for halogen, stays cool so it does not dry your specimen, and holds colour temperature as you dim it. Halogen remains available if your protocol was validated on it or you need its warmer spectrum for particular stains.
Q5 Can a camera be attached to this microscope?
Yes. The sliding binocular head accepts our XCAM Mini and X Cam C-mount cameras through an adapter. If documentation is a daily requirement rather than an occasional one, consider a trinocular model instead so you keep both eyepieces and the camera port live at the same time.
Q6 What is the delivery time and where do you ship?
Stock units dispatch in 3–5 business days. We ship across India by surface and air freight, and export with wooden crating on request. Institutional and tender orders with specific documentation requirements are handled by our sales desk — call +91 8727015757.
Q7 How is it serviced and are spares available?
The unit carries a one-year warranty on body, optics and electricals. We stock spares — objectives, eyepieces, LED assemblies, stage parts — for ten years from the date of manufacture. Most issues are resolved over a video call; parts ship direct to your lab.
Q8 What is the price of the CXL Bi Lab Microscope?
Pricing depends on configuration (LED or halogen, objective set, camera adapter) and order quantity, so we quote per enquiry rather than list a single figure. Send your requirement through the form below or on WhatsApp and you will have a written quotation with GST and freight the same working day.
