LB-625T Research Upright Metallurgical Trinocular Microscope

with Infinite Optical System,

Infinite LWD Plan Objectives 5x, 10x, 20x, 50x, 100x and LWD Condenser

LB-625T Research Upright Metallurgical Trinocular Microscope with Infinite Optical System, Infinite LWD Plan Objectives and LWD Condenser have been developed for research with a number of pioneering design in appearance and functions, with wide field of view, high definition and bright/dark field semi-apochromatic metallurgical objectives and ergonomical operating system, they are born to provide a perfect research solution and develop a new pattern of industrial field. The objectives could be motorized controlled by the buttons on the microscope front base, the illumination intensity will change after changing objective.

Labomed Inc. is certified by ISO 9001, CE Conformity and is FDA Licensed.


Features

  1. Excellent Infinite Optical System
  • With the excellent infinite optical system, LB-625T series upright metallurgical microscope provides high resolution, high definition and chromatic aberration corrected images which could display the details of your specimen very well.
    Modular Design.
  1. Modular Design
  • LB-625T series microscopes have been designed with modularity to meet various industrial and material science applications. It gives users flexibility to build a system for specific needs.
  1. Convenient Control
 
1) Motorized Objective Switch and ECO function.
Objectives could be switched by simply pressing the rotating buttons. Users could also self-define two of the most commonly used objectives and switch between these two objectives by pressing the green button. The light intensity will be automatically adjusted after you change the objective.
The microscope light will be off automatically after 15 minutes from operators leaving. It not only saves energy, but also saves the lamp lifetime.
(2) Shortcut Buttons.
With this shortcut button, the user could switch 2 pre-set objectives fast. This shortcut button also could be set with other functions by users.
  1. Comfortable and Easy to Use
 
(1) NIS45 Infinite Plan Semi-APO and APO Objectives.
With high transparent glass and advanced coating technology, NIS45 objective lens can provide high resolution images and accurately reproduce the natural color of the specimens. For special applications, a variety of objectives is available, including polarizing and long working distance.

(2) Nomarski DIC.
With newly designed DIC module, the height difference of a specimen which can not be detected with brightfield becomes a relief-like or 3D image. It is ideal for the observation of LCD conducting particles and the surface scratches of hard-disk etc.

(3) Focusing System.
In order to make the system suitable for the operating habits of the operators, the knob of focusing and stage can be adjusted to the left-hand side or right-hand side. This design makes the operation more comfortable.

(4) Ergo Tilting Trinocular Head.
Eyepiece tube can be adjustable from 0 ° to 35 °,Trinocular tube can be connected to DSLR camera and digital camera, having a 3-postion beam splitter (0:100, 100:0, 80:20), the splitter bar can be assembled on the either side according to user’s requirement.

  1. Various Observation Methods.

 

Darkfield (Wafer)
Darkfield enables the observation of scattered or diffracted light from the specimen. Anything that is not flat reflects this light while anything that is flat appears dark so imperfections clearly stand out. The user can identify the existence of even a minute scratch or flaw down to the 8nm level-smaller than the resolving power limit of an optical microscope. Darkfield is ideal for detecting minute scratches or flaws on a specimen and examining mirror surface specimens, including wafers.

Differential Interference Contrast (Conducting Particles)
DIC is a microscopic observation technique in which the height difference of a specimen not detectable with brightfield becomes a relief-like or three- dimensional image with improved contrast. This technique utilizes polarized light and can be customized with a choice of three specially designed prisms. It is ideal for examining specimens with very minute height differences, including metallurgical structures, minerals, magnetic heads, hard-disk media and polished wafer surfaces.

Transmitted Light Observation (LCD)
For transparent specimen such as LCDs, plastics, and glass materials, transmitted light observation is available by using a variety of condensers. Examining specimen in transmitted brightfield and polarized light can be accomplished all in one convenient system.

Polarized Light (Asbestos)
This microscopic observation technique utilizes polarized light generated by a set of filters (analyzer and polarizer). The characteristics of the sample directly affect the intensity of the light reflected through the system. It is suitable for metallurgical structures (i.e., growth pattern of graphite on nodular casting iron), minerals, LCDs and semiconductor materials.
