ATS100 ATS300 Zoom Stereo Microscope
The ATS100 and ATS300 series are zoom stereo microscopes with a unique optical design, offering an extra long working distance of 105mm and a large depth of field.

Product Overview
The ATS100 and ATS300 series are zoom stereo microscopes with a unique optical design, offering an extra long working distance of 105mm and a large depth of field. The ATS100 uses horizontal axial drive control knobs for magnification adjustment, while the ATS300 uses a turret body for precise, parfocal switching. Both models feature high eye-point, extra wide-field eyepieces with a 23mm field of view and 45° inclined eyetubes, enabling comfortable long-duration use. They are designed for precision assembly, mineral specimen research, and inspection of small industrial components.

Problems It Solves
- Short working distance microscopes force operators to remove tools or reposition components during inspection
- Fixed magnification systems require frequent objective changes, increasing inspection time and error risk
- Eyepieces with low eye-point cause discomfort and eye strain during prolonged use
- Lack of parfocal performance in zoom systems leads to refocusing after each magnification change
- Inadequate field of view limits the operator's ability to see the full context of a small component

Customization Options
- Choose between ATS100 (knob-driven zoom) and ATS300 (turret-driven zoom) based on required precision and switching speed
- Select from multiple objective lenses: 1X, 2X, 3X, 4X for different magnification needs
- Use optional eyepieces: SWH10X, SWF15X, SWF20X, SWF30X to adjust magnification and field of view
- Attach optional illumination: bottom fluorescent or top halogen lamp for specimen-specific lighting
- Mount on SD1~SD18 universal stands or U1~U4 series stands with compatible mounting dimensions
- Add mechanical stage S7665 or S10086 with pre-drilled screw holes for secure mounting
- Use CCD adapters C0.3-S, C0.5-S, C1.0-S or digital camera adapters DT01, PT02 for imaging integration
- Install 1X CCD adapter with micrometer CDM1.0 when using a CCD system
Comparison With Other Options
| ATS100 with knob-driven zoom | Same optical design and working distance, but ATS300 uses a turret body for faster, parfocal magnification switching with better orientation stability |
|---|---|
| Fixed magnification stereo microscope | The ATS100/ATS300 provides continuous zoom without objective changes, reducing setup time and focus drift |
| Standard bench microscope with short working distance | The 105mm working distance allows tools and components to remain under the optics during inspection, unlike shorter-distance models |
Use Guide
- Adjust interpupillary distance to 52-76mm before focusing to ensure a single merged image
- Set diopter correction on the right eyepiece first, then focus the left eye with the main focus knob
- Use the 105mm working distance to position soldering irons, tweezers, or probes under the optics
- For the ATS300, rotate the turret to change magnification; the image remains in focus across steps
- For the ATS100, turn the horizontal knobs smoothly to adjust zoom; avoid abrupt movements
- When using optional halogen lamp, ensure the power supply matches 6V/10W to prevent damage
- Install mechanical stage only if the stand has pre-drilled screw holes; otherwise, request a custom stand

Frequently Asked Questions
What is the working distance on the ATS100 and ATS300?
105mm. This allows tools and components to remain under the optics during inspection.
Can I use this microscope for jewellery or watchmaking assembly?
Yes. The 105mm working distance and high eye-point eyepieces are ideal for precision micro-assembly tasks.
How do I change magnification on the ATS100 vs ATS300?
ATS100 uses horizontal axial drive knobs for continuous zoom; ATS300 uses a turret body for discrete, parfocal steps.
What illumination options are available?
Bottom 5W fluorescent lamp and top 6V/10W halogen lamp are both optional and can be used separately or together.
Can I attach a camera to this microscope?
Yes. Use CCD adapters C0.3-S, C0.5-S, C1.0-S or digital camera adapters DT01, PT02 for camera integration.
Does the mechanical stage fit all stands?
No. The mechanical stage S7665 or S10086 requires pre-drilled screw holes. Confirm stand compatibility before ordering.
