BS-3090
BS-3090F(LED)
BS-3090 is a research level zoom stereo microscope with infinite parallel Galileo optical system. Based on Galileo optical system and Apochromatic objective, it can provide real and perfect microscopic images on details. The excellent ergonomics and user-friendly operating system can truly allow users to experience a simple and comfortable work. The zoom ratio is 18:1, with 10× eyepiece, the magnification range is 7.5×-135×. BS-3090 can meet the research demands of life sciences, biomedicine, microelectronics, semiconductors, materials science and other fields of research needs.BS-3090 has great value in a variety of applications such as life science and medical research, including dissection, Zebrafish research, live cell imaging, IVF, biological experiment, chemical analysis and cell culture. It also can be used in Industrial areas for PCB, SMT surface, electronics inspection, semiconductor chip inspection, metal and materials testing, precision parts testing, coin collecting, gemology and gemstone setting, engraving, repair and inspection of small parts.1. BS-3080A has tilting viewing head for comfortable operation. BS-3080A has tilting viewing head from 5 to 45 degrees, can be flexibly adjusted for different operators with different posture.2. Large zoom ratio 12.5:1. BS-3080 has large zoom ratio of 12.5:1, zoom range from 0.63X to 8X, with click stop for main magnifications, the images remain clear and smooth during zoom magnifying.
3. Apochromatic objective. Apochromatic design has significantly improved the color reproduction of the objective. Correcting the axial chromatic aberration of red/green/blue/purple, and converge them on a focal plane, the objective is able to present the real color of the samples. 0.5X, 1.5X, 2X apochromatic objectives are optional.
4. Aperture diaphragm adjustment. Shift the aperture diaphragm lever in front of the microscope to adjust depth of field for high-quality image.
5. LED fluorescent attachment. The EPI-Fluorescent Attachment is equipped with 6-hole turntable fluorescent modules, it can accommodate up to five fluorescent modules and one bright field module. Four band LED light source is used to change the light source color and adjust the brightness through the LED light source controller. It include following parts: (1) Epi-fluorescent Attachment. (2) 1/4 λ Plate. (3) Control Box. (4) Light Shading Plate. (5) Light Source. (6) Bright Field Filter Cube.

1. Trinocular viewing head for comfortable operation. The interpupillary distance and diopter can be adjusted, users can operate the microscope with the most comfortable gesture. This can minimize the visual fatigue caused by long-term observation. Trinocular tube with C-mount can be used to connect different digital cameras.
