Product Description
BS-1008 adopts semi-apochromatic parallel optical imaging system, and uses advanced multi-layer coating technology, which perfectly correct the imaging on the edge of field of view, get high-resolution and high contrast images, and naturally restore the true colors of observed objects. 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-1008 is BS-1008A(does not have stop) and BS-1008B(has stop at main magnification), it has 0.7X to 5.6X 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 Working Distance of BS-1008 decreases with the increase of the magnification of the Auxiliary Lens, and its object NA or Zoom Range increases with the increase of the magnification of the Auxiliary Lens. Therefore, the Auxiliary Lens can be selected according to the Working Distance or Zoom Range (The real Zoom Range is also determined by the Auxiliary Lens).
The core of choosing TV Lens with different magnification is to match your own camera. From the table’s Zoom Range column, one can find with the increase of TV Lens’ magnification, the Zoom Range of the system increases in the same proportion, but it will not have a great effect on the optical resolution. In order to save money, it is recommended to choose a small size camera, such as 1/3″ camera.
Of course, in order to improve the signal-to-noise ratio or imaging quality of the camera, one can also choose a large size camera. Large size often means large pixel size, while large pixel size often means large dynamic range and high signal-to-noise ratio.
This package contains: BS-1008 Main Body, including Auxiliary Lens Module, Middle Zoom Module, TV Lens, Camera Adapter Tube and Bracket Adapter
