Welcome to ToupTek
TZM0745A is designed with modularized structure which is based on the bilateral parallel light path.with excellent optical performance. The TZM0745A can be used in the fields of machine vision, industrial inspection and scientific research. (TZM0745_en Manual)
The basic module of TZM0745A series monocular zoom object is TZM0745A-W100-TV100-A50
- Provide basic zoom objective W100-TZM0745A-TV100 with 0.7X~4.5X zoom range
- Large optical zoom ratio: 6.5X
- Larger NA: 0.018-0.092 (When using 1x Auxiliary Lens)
- Higher resolution: 18.6um-3.65um (When using 1x Auxiliary Lens)
- Larger field of view: 2.44mm-31.43mm(Object plane)
- Larger sensor size: 2/3 Inch (When using 1x TV Lens)
- Working distance: 37.5mm-160mm
- Parfocal in zoom range
- Compatible with infinity objectives (both biological and metallographic)
Auxiliary Lens
The replaceable Auxiliary Lens, which can be threaded to the bottom of the Middle Zoom Module(code Wbbb), bbb represents the magnification of Auxiliary Lens. Different magnification of Auxiliary Lens defines the entire magnification of TZM0745A series MZO, resulting different working distance as well. For example, compared with the W100 Auxiliary Lens with 1.00x magnification reaches 80mm working distance, whilee W050 Auxiliary Lens will have a reduced magnification to half and the working distance will be extended to about 160mm. Auxiliary Lens and its corresponding optical parameters are shown in Table.
| Order number | Magnification | Working distance(mm) | Field of view in the object side(TV050，1/3"sensor) | |
|---|---|---|---|---|
| Lower | Higher | |||
| W050 | 0.5X | 160 | 34.28mm | 4.28mm |
| W075 | 0.75X | 105 | 20.81mm | 2.86mm |
| W100 | 1.00X | 80 | 17.14mm | 2.14mm |
| W150 | 1.50X | 51.5 | 11.43mm | 1.43mm |
| W200 | 2.00X | 37.5 | 8.57mm | 1.07mm |
Note: The same Auxiliary Lens with different TV lens is just used to adapt to different image sensor, size which will not have much impact on the MZO field of view.
TV Lens
TV Lens (code TVccc), which can be threaded to the top of the Middle Zoom Module, ccc is the magnification of TV Lens. TV Lens with different magnification is used to adapt to sensors with different size. For example, the same field of view could be obtained when TV100 is used with a 2/3” size sensor and TV050 is used with a 1/3” size sensor. TV Lens and its corresponding optical parameters are shown in Table
| Order number | The maximum compatible sensor size |
|---|---|
| TV050 | 1/3" |
| TV075 | 1/1.8" |
| TV100 | 2/3" |
| TV150 | 1" |
| TV200 | 4/3" |
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.

| Remarks |
When using coaxial lighting, low magnification may produce vignetting. When using infinity objectives as Auxiliary Lens Module (adapter available), the PMAG、FOV and NA of the TZM0745A depends on the parameters of the objectives. |
||||||||||
WD: Working Distance;
PMAG: Primary Magnification;
FOV: Field of View in the object side;
NA: Numerical Aperture;
Note: Infinity corrected objectives limit system's usable zoom range due to uneven illumination.
The maximum sensor size is 2/3".
