BS-1108 series Monocular Zoom Microscope 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 BS-1108 is BS-1108A (without click stop) and BS-1108B (with click stop at main magnifications), it has 0.15X to 1.20X zoom range and 1:8 zoom ratio. It is a high-quality precision Monocular Zoom Objective that provides high resolution and large depth of field.

The main features are shown below:

1. Provide basic zoom objective BS-1108A with 0.15X~1.20X zoom range.
2. Large optical zoom ratio: 1:8.
3. Larger NA: 0.008-0.046 (When using 1.00x Auxiliary Lens).
4. Higher resolution: 33.1um-5.9um (When using 1.0X Auxiliary Lens).
5. Larger sensor size: 2/3” (When using 1X TV Lens).
6. Working distance:130mm (When using 1.0X Auxiliary Lens).
7. With adjustable BFL, parfocal in zoom range.
8. With adjustable center, the image center remains unchanged from 1.20x to 0.15x.
9. Compatible with infinity objectives (both biological and metallographic).
10. Compact size: 164 mm (length)*40 mm (diameter).
11. Auxiliary Lens with 1.00X magnification (Customizable).
12. TV Lens with 1.00X magnification (Customizable).
13. Brightness adjustable LED Direct Ring Light (Optional).

Table 1 BS-1108’s Accessories and Its Functions

The BS-1108 main body consists of Auxiliary Lens Module, Middle Zoom Module and TV Lens Module.

These 3 modules comprise the main Monocular Zoom Objective.

To get good illumination and ensure the image quality, LED Direct Ring Light Module (Optional).

To get good and stable support, the Bracket Adapter Module should be carefully chosen.

Finally, to form the Video Monocular Zoom Objective, Camera Module (Optional) should be chosen.

The Adapter Rings and their relationship with the Bracket are shown following.
