MIC-50M research metallurgical microscope major characteristic
Viewing head with multi-splitting ratio
MIC-50M viewing head is designed of multiple options for splitting ratio. With wide beam imaging system, 26.5mm super wide filed of view is available.
Trinocular head with erect image, splitting ratio Binocular:Trinocular= 100:0 or 0:100.
The moving direction of samples is as the same as observed. Trinocular head with inverted image, splitting ratio Binocular: Trinocular=100:0 or 20:80 or 0:100. Except for concentrating 100% light to eyepiece tube or camera tube, there is another option with 20% light to eyepiece tube and 80% to camera tube, so that eyepiece observation and image output can be available at the same time.
The polarizer and analyzer in polarization system contribute to eliminate the stray light in semiconductor and PCB detection, image with clear detail is achievable. There are fixed analyzer and rotatable analyzer for option. The sample can be observed at different polarizing angles with 360°rotatable analyzer. Besides, this polarization system can be upgraded to Nomarski differential interference contrast system after installing a new developed DIC attachment. Nomarski differential interference contrast system
The weeny asperities on the surface which can not be found in bright field, is able to be detected by using U-DICR attachment to create high contrast background. It is widely used for testing the conductive particle of LCD, surface scratch of precision disk.
Linkage between the neutral density filter and the switch for BF & DF
The lever in front of illuminator is used to switch between bright field and dark field, and it is in tandem with a neutral density filter (ND50). When you switch from DF to BF, the built-in ND50 filter takes the role to decay the light intensity. More scientific and more comfortable.
The included angle between optical axis and rotation axis of multiple nosepiece is decreased to 15°. It is helpful to improve the accuracy of centering and focusing. Seven objectives at most can be assembled at the same time. Continuous and reasonable magnifications from low to high is achievable.
■ The intensity can be flexibly adjusted by the dimming device which is located on the right side of frame. The voltage change all-digital displays. Adjusting intensity and coaxial focusing at the same time, improves the work efficiency.
■ Reflected or transmitted illumination can be switched by the button on the digital dimming display. Using the RE-SET button to keep the light intensity at around 8V (with a camera mark on the dimming display) which is an optimal voltage for photomicrography.
■ Four built-in filter holders with three standard filters, one empty holder for optional filter. All the filters can be moved out the optical path by pulling out the lever.
■ Low position coaxial focusing system with tension adjustment. The coarse range is 25mm and the fine precision is 0.001mm. The height of a tiny sample,such as solder ball, can be measured. Stage with adjustment on the right hand
4 inches double-layer mechanical stage, with the lock device to limit Y axis movement. It is widely used in horizontal detection to avoid missing. Glass plate is attachable for transmitted light.
Transmitted and reflected illuminator
12V 100W long lifetime lamp-house with PHILIPS 7724 halogen bulb, provides bright and uniform light.
New swing-out type achromatic condenser (N.A.0.9) optimizes the performance of
Kohler illumination in lower magnification and corrects the chromatic and spherical aberration
Professional LWD semi-apochromatic metallurgical objectives
■ BD objectives are designed for all-purpose, available for bright field/dark field/ polarizing/DIC observation. With plenty passed light, the efficiency of sample inspection is improved.
■ Strictly using high transmittance lens and advanced coating technology, restores the natural color of samples.
■ Aluminum cover reduces the weight, prevents the pollution, and also improves the controllability of nosepiece.
■ Semi apochromatic design improves the contrast and definition of images.
■ Long working distance meets the demands of professional detection, is widely applied in all kinds of industrial fields.
■ These objectives also can be used in fluorescence observation.
■ Professional LWD bright field objective for option.
High eye-point ultra wide field plan eyepieces
■ MIC-50M eyepiece breaks through 22mm conventional field of view, reaching to 25mm and 26.5mm, much smoother and wider field of view, is helpful to improve the work efficiency.
■ Locating pin on eyepiece inserts into the eyepiece tube, fixing the eyepiece for easy focusing. Bigger adjustable range of diopter from -8 to +5, meets more demands of different users.
■ Eyepiece cup can be turn up to avoid external stray light. Spectacle-wearers should turn down the cup to protect both spectacles and eyepieces.
MIC-50M is available for multi-observation, such as bright field, dark field (reflected light only), polarizing, DIC (reflected light only).
