QZ660P Series Monocular Zoom Objective, with Parallel Light Path

QZ660P series 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 Five Basic Modules of QZ660P Series

The modular design of QZ660P series monocular zoom objective is showed in Figure below. The design consists of five basic modules, including Middle Zoom Module, Auxiliary Lens Module, TV Lens Module, Bracket Adapter Module and Optional Module.

QZ660P Main Body includes Auxiliary Lens Module, Middle Zoom Module, TV Lens, Camera Adapter Tube and Bracket Adapter

1. Middle Zoom Module

The Middle Zoom Module, which is the main body of QZ660P series monocular zoom objective. QZ660P represents the code of Middle Zoom Module and letter a represents the auxiliary code of Middle Zoom Module. Details are listed in Table below:

The order number and function of the Middle Zoom Module

2. Auxiliary Lens Module

The replaceable Auxiliary Lens, which can be threaded to the bottom of the middle zoom module. Different magnification of Auxiliary Lens defines the entire magnification of QZ660P series monocular zoom objective, resulting different working distance as well. For example, W3100 Auxiliary Lens with 1.00x magnification reaches 86mm working distance, while W3050 Auxiliary Lens will have a reduced magnification to half and the working distance will be extended to about 174mm. Auxiliary Lens and its corresponding optical parameters for QZ660P are shown in table below:

The order number and optical parameters of Auxiliary Lens

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 monocular zoom objective

3. TV Lens

The TV Lens, which can be threaded to the top of the Middle Zoom Module. 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 V3100 is used with a 2/3” size sensor and V3050 is used with a 1/3” size sensor. TV Lens and its corresponding optical parameters are shown in Table below:

Note: Smaller image sensors can also be used for TV Lens with higher magnification, but in this way, the FOV of monocular zoom objective will be reduced.

4. Bracket Adapter

Bracket Adapter used for brackets with different mounting apertures and is sheathed in the middle of monocular zoom objective. There are two adapter available: A50 and A45. The installation method of the bracket adapter and bracket is shown in Figure below:

5. The Optional Module

The optional modules include LED Direct Ring Light Module (including LED Direct Ring Light Module and LED Direct Ring Polarization Light Module) and Coaxial Light Module (composed of Coaxial Light Adapter and LED Spot Light). The currently possible samples are shown in Table below:

How to Configure QZ660P Series Monocular Zoom Objective

The corresponding parameters of QZ660P series monocular zoom objectives are listed in Table below. A specific combination can be determined according to the following steps:

1. Confirm the possible range of

a) FOV and

b) Working Distance in the object space to choose the Auxiliary Lens.

2. Choose the M26x0.705 to M20x0.705 Objective Adapter, if the M20x0.705 infinity objective is used.

3. Confirm the camera Image Area Size, it can be

a) Sensor Size (1/x in inch),

b) Image Diagonal Length,

c) Image Width or

d) Image Height to choose the right TV Lens.

4. Choose the 45mm or 50 mm adapter according to the diameter of the bracket hole diameter .

5. Choose the LED Direct Ring Light Module for the reflective illumination.

6. Choose the Coaxial Light Module if coaxial illumination is required.

7. Choose the Transmissive Light Module if transmissive illumination is required.

8. Choose the Camera Module. We offer a variety of microscope cameras. Customers could get the detailed information of our cameras on the official website (https://www.nbicoe.com)
