Welcome to ToupTek
TZM0640 series MZO (Monocular Zoom Objective) is an ideal choice for machine vision, industrial inspection, scientific research and education. The design is based on the bilateral parallel light path principle and the modular design concept, with superior optical performance and strong compatibility.
The basic module of TZM0640 MZO is TZM0640-W3100-TV3100-A50, it has 0.6X-4.0X zoom range and 6.5X zoom ratio. It is a high-quality precision MZO that provides high resolution and large depth of field.

- Working distance range: 86mm-174mm
- With adjustable BFL, parfocal in zoom range
- With adjustable center, the image center remains unchanged from 4.0x to 0.6x
- 45mm or 50mm Bracket Adapter(Optional)
- Compatible with infinity objectives (both biological and metallographic)
- Compact size: 194 mm (length) × 40 mm (diameter)
- Auxiliary Lenswith 0.50x, 0.75x, 1.00x magnification (Optional)
- TV Lenswith 0.50x, 0.75x, 1.00x magnification (Optional)
- Brightness adjustable LED Direct Ring Light(Optional)
- Brightness adjustable LED Direct Ring Polarization Light(Optional)
- Brightness adjustable LED Coaxial Light(Optional)
- LED Transmissive Light(Optional)
Auxiliary Lens
| Order number | Magnification | Working distance(mmm) | Field of View in the object side(TV3050，1/3"sensor) | |
| Lower magnification | Higher magnification | |||
| W3050 | 0.5X | 174 | 60.00mm | 3.00mm |
| W3075 | 0.75X | 115 | 40.00mm | 2.00mm |
| W3100 | 1.00X | 86 | 30.00mm | 1.50mm |
Note: The same Auxiliary Lens with different TV lens is just used to adapt to different size image sensor, which will not have much impact on the field of view of the MZO.
TV Lens
| Order number | PMAG | The maximum compatible sensor size |
|---|---|---|
| TV3050 | 0.50X | 1/3" |
| TV3075 | 0.75X | 1/1.8" |
| TV3100 | 1.00X | 2/3" |
Note: Smaller image sensors can also be used for TV Lens with higher magnification, but in this way, the FOV of MZO will be reduced.
