Other Modules

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.
Auxiliary Lens

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"
TV Lens
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".
