TZM0748A Monocular Zoom Objective(MZO), Auxiliary Lens-Main Zoom Module-TV Lens, TZM0745B-W075-TV075 . (CAT#: STEM-MO-0046-TP)

The Application of the TZM0745B Series MZO
TZM0745B series MZO uses finite opical system structure with excellent optical performance(TZM0745B Manual).

The TZM0745B series MZO is an ideal choice for most applications that requires multiple magnifications or for those that prohibits continual manual refocusing. The applications of the TZM0745B series MZO are:

Machine vision
Small details inspection
Industrial inspection especially electronic components
Scientific research
Medical industry
Education industry
The Structure and Characteristic of TZM0745B Series MZO
The modular design of TZM0745B series MZO is showed below. The design is based on the finite optical system path principle and consists of five basic modules. The five basic modules are: The Main Body including Middle Zoom Module, Auxiliary Lens Module, TV Lens Module, Bracket Adapter Module and Optional Module.

Packing Information

In order to configure the TZM0745B series MZO, we name TZM0745B series products with a series module code, which is a combination of code of different modules and connected with crossbar “-” as shown in the following example:

TZM0745Baa-Wbbb-TVccc-Add

In the above expression, aa represents the main body type, bbb represents the magnification of the auxiliary objective lens, ccc represents the magnification of the TV lens, and dd represents the diameter of the adapter. With this paradigm, user can understand the meaning and function at a glance. For example, if a MZO is composed of Middle Zoom Module TZM0745B, Auxiliary Lens W100(1.00x), TV Lens TV050(0.5x) and 50mm Bracket Adapter A50, the final MZO can be expressed as:

TZM0745B-W100-TV050-A50

Currently available TZM0745Baa: TZM0745B;

Currently available Wbbb: W075 and W100;

Currently available TVccc: TV050 and TV075;

Currently available Add: A50 and A45;

Current available Optional Module: TZM0745BDRL and TZM0745BTL.

Module of TZM0745B Series MZO
There are four models for TZM0745B, they are

TZM0745B-W100-TV075
TZM0745B-W100-TV050
TZM0745B-W075-TV075
TZM0745B-W075-TV050
Which are the combination of TZM0745B main body, auxiliary lenes and TV lenes with different magnification. For example: model TZM0745B-W100-TV050, it represents the magnification of main body is between 0.7X and 4.5X, the magnification of the Objective is 1.0X and the magnification of TV Lens is 0.5X.
