CDM-812Research-grade upright metallographic microscope
CDM-812 adopts excellent infinity optical system and modular function design concept, which can easily upgrade the system and realize polarized light observation. The compact and stable high-rigidity body fully reflects the anti-vibration requirements of microscope operation. The ideal design with ergonomic requirements makes the operation more convenient and comfortable, and the space is wider. It is suitable for microscopic observation of metallographic structure and surface morphology. It is an ideal instrument for metallurgy, mineralogy and precision engineering research. Suitable for the electronics, metallurgy, chemical and instrumentation industries for viewing transparent, translucent or opaque materials such as cermets, manifolds, printed circuit boards, liquid crystal panels, films, fibers, coatings and other non-metallic materials. It is suitable for observation and analysis by medicine, agriculture, forestry, public security, schools and scientific research departments.
The infinity transflective metallographic microscope system combines a traditional optical microscope with a computer (digital camera) through photoelectric conversion, not only for microscopic observation on the eyepiece, but also on a computer (digital camera) display screen. Observe real-time moving images and edit, save, and print the images you need.
三、Instrument characteristics
It combines multiple creations from the exterior to the performance of the international design style. The multi-speed splitter provides a new and comfortable viewing experience. Committed to expanding the new landscape of the industry, providing customers with comprehensive industrial inspection solutions. Integrating the advantages of the new metallographic microscope technology, providing customers with cost-effective metallographic analysis and industrial inspection solutions with excellent imaging performance and comfortable operating experience, LMPlan series long working distance metallographic objective lens enhances the level of chromatic aberration correction. Adjusting the membrane design to further enhance the image resolution and color reproduction. The observation tube of the neonatal bed comfortable angle (30°) can alleviate the tension and fatigue of the user under long working conditions and ensure the observation state. Observe the scale on the tube to allow the user to adjust the distance range.
High eye point super wide field flat field eyepiece
Matching the ultra-wide field of view cylinder, the field of view of the eyepiece is also increased from the traditional 22mm to 25mm and 26.5mm, providing a flatter viewing range, improving work efficiency, and a larger range of diopter adjustment range to meet the needs of more users. . The eyepiece adopts a locating pin structure for convenient visual adjustment. The foldable rubber eye shield prevents external stray light interference, and the user can turn the eyecup down to prevent the glasses from contacting the eyepiece, scratching the eyeglasses and the eyepiece.
Infinity long working distance semi-apochromatic bright and dark field metallographic environment
The light and dark field environment can be used for bright field, dark field, polarized light and differential interference observation with only one lens. The dark field image brightness is enhanced to improve the sample detection ability. Strictly select high-permeability lenses and advanced coating technology to truly restore the natural color of the sample. The bright and dark field environment is made of aluminum, which greatly reduces the weight and contributes to preventing environmental pollution and improving the handling of the environment. . The semi-apochromatic design has excellent chromatic aberration correction performance, which improves the contrast and sharpness of the observed image. Long working distances are widely used in various inspection fields to easily achieve non-destructive testing.
Context converter, porous optional
The porous environment converter can continuously and reasonably observe the low, medium and high magnification of the observation points of the same specimen. The new environment converter reduces the angle between the optical axis and the rotating axis to 15o, improving alignment accuracy and parfocal precision, and a more compact appearance.
Right hand platform with locking device
The 4-inch large-stroke mechanical platform has a wide range of applications and features a Y-axis movement lock function. It restricts the movement of the Y-axis after full locking. It can be used for lateral detection to prevent the detection of missing errors during the detection of array devices. A 4-inch glass stage plate can be used for transmitted light viewing.
Multi-speed splitting ratio observation head
With a wide beam imaging system design, it supports 26.5mm ultra-wide field of view, giving you a new big field of view experience.
The two-step positive hinged trinocular viewing tube ensures that the direction of movement of the sample is consistent with the direction observed through the eyepiece, making the operation more convenient.
Polarization system
The polarization system includes a polarizer and an analyzer for polarized light detection. In semiconductor and PCB inspection, stray light is eliminated and the details are clearer. The analyzer is divided into a fixed analyzer and a 360o rotary analyzer. The 360o rotary analyzer can easily observe the state of the specimen under different polarization angles without moving the specimen. A differential interferometer can be loaded on the basis of the polarization system to establish a Normansky differential interference contrast system.
The newly developed DIC differential interference component can transform the subtle height difference under the bright field observation into a high contrast light and dark difference and express it in a three-dimensional relief form, such as LCD conductive particles and precision disk surface scratches.
Neutral Density Filters Linked Bright and Dark Field Observation Design
The lever on the front of the illuminator can be switched between bright and dark field observations with neutral density filter linkage. Since the dark field observation usually requires the light source to be brighter than the bright field observation, this function design can prevent the user from being stimulated by strong light when switching from the dark field to the bright field, thereby improving the comfort of use.
Color filter
There are 3 color filters on the mirror base and a fourth optional one. The lever design makes it easy to move the filter into/out of the light path.
Focusing mechanism
The low-hand dimming device on the bottom side of the mirror can flexibly adjust the light intensity and display the corresponding voltage on the digital dimming screen. It can be used with the left hand to adjust the focus to improve work efficiency. The left and right low hand position coarse and fine coaxial focusing mechanism with elastic adjustment device. The coarse adjustment stroke is 25mm and the fine adjustment precision is 1um. It can be used to measure the height of very fine objects in the Z-axis direction, such as kicking.
Transflective lighting, light source compatible
The 12V100W ultra long life light box uses PHILIPS 7724 halogen lamp to provide a sufficient and uniform lighting environment for the system. The shake-out achromatic concentrating mirror system optimizes the low-power performance of the Corolla illumination and effectively corrects the chromatic aberration and obtains the ideal image.
