Product Description

BS-1210 Series Monocular Microscope

Introduction

BS-1210 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.
For applications that require different magnification, Auxiliary Lens or infinity objectives with different magnification can be attached to the front end of the Middle Zoom Module.
For application that require different sensor size, TV Lens with different magnification can be attached to the back end of the Middle Zoom Module.
The basic module of BS-1210 is BS-1210A (without click stop) and BS-1210B (with click stop at main magnifications), it has 0.6X to 6.0X zoom range and 1:10 zoom ratio. It is a high-quality precision Monocular Zoom Objective that provides high resolution and large depth of field.

Auxiliary Lens Module

TV Lens Module

The BS-1210 main body consists of Auxiliary Lens Module, Middle Zoom Module and TV Lens Module.
These 3 modules comprise the main Monocular Zoom Objective. User can choose different Auxiliary Lens and TV Lens to satisfy the specific requirement.
To get good illumination and ensure the image quality, LED Direct Ring Light Module (Optional) or Coaxial Light Module (Optional) should be chosen according to the application.
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.

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 BS-1210 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.
