Comparative Microscope

Specification:

   The WBY-20B comparative microscope uses optical magnification to simultaneously observe images of objects within the left and right object fiels through the same set of eyepieces. It employs methods such as field cutting, overlapping to compare two objects macroscopically or microscopically. Due to its clear imaging and high resolution, it can identify minute differences, achieving the purpose of distinguishing authenticity. This product is an ideal instrument for public security, procuratorial, and judicial institutions for document examination, trace evidence analysis, and school teaching (used for comparing and identifying bullet casings, tool marks, fingerprints, seals, text, currency, etc.), and is also suitable for banks, archaeology, electronics, biology, agriculture, and other industries and departments that require comparison and identification of objects.

II. Technical Parameters

• Optical total magnification: 5X-120X, optional 2X magnifying lens and 0.4X reducing lens to extend the magnification range to 2X-240X
• Wide-field eyepieces: WF10X/φ22mm, WF20X/φ13mm each pair
• Objectives: 0.5X, 1X, 1.5X, 2X, 4X, 6X using a six-hole objective turret, fixed magnification change, the turret is designed to stop, reliable operation. Equipped with a 2X magnifying lens and a 0.4X additional objective lens, suitable for observing seal graphics and extending optical magnification
• Tilted binocular head: 10°～55°, humanized design; interpupillary distance: adjustable range 48mm-75mm
• Ouchscreen electronic control: Can achieve computer software control of left and right single fields, docking field, overlapping field; left and right stages up, down, forward, backward, single-side movement, and bilateral linkage; left and right objectives magnification changes, etc.; the instrument can be operated manually or through computer software to move the stage along the X/Y/Z axes, link the left and right stages, and rotate the stage surface horizontally; the instrument can be remotely electronically controlled for comparison
•  Illumination system: 12V50W air-cooled strong light reflector source and high-power LED source each pair, both use touch-independent switches, can be lit separately or used together, the brightness of each light source can be adjusted separately, the illumination direction and angle can be arbitrarily adjusted. Input 220V, output 12V, meets international safety standards
• Coaxial light: 45° reflection angle
• Polarized light: 0-360° rotatable, 90° orthogonal
• Stage travel: front and back 50mm, left and right 55mm, electric/manual 40+60mm
•  Column electric lift travel: 0-150mm
• Equipped with dedicated shearing fixture: diameter from 1 to 8mm, can fix and hold screwdrivers, cylindrical keys,wires, lead wires, etc., fine traces
• Photography system: Uses a front-mounted photography device, equipped with various camera output ports, optional DSLR cameras can capture static images from the front, provides substantive proof documents for the legal use of the front-mounted photography device
• Video system: Equipped with a video cylinder, optional high-definition digital camera, criminal image processing software computer, etc., can collect, process, and archive dynamic and static images; visual and video devices can be observed synchronously, i.e., the image observed by the eyepiece can be displayed synchronously on the computer monitor, making observation more convenient
•  Video acquisition: High-definition digital camera, sensor model and size (mm): 5.1M/AR0521(C), 1/2.5"(5.70x4.28); pixel (μm): 2.2x2.2; G light sensitivity/dynamic range SN ratio: 18.8ke-/lux, 73dB, 40dB; FPS/resolution: 7.0@2592x1944, 27.7@1296x972, 100.5@648x486; sampling average: 1x1, 2x2, 4x4; exposure time: 0.2ms~2000ms
• Equipped with professional forensic image processing software: capable of comparing entire images, or using various selection methods (rectangle, freeform, circle, magic wand, etc.) for overlapping, omnidirectional cutting comparison, image measurement, etc.; enables automatic uniform expansion of bullet and cartridge case cylindrical traces; corrects traces on various distortions such as linear deformation correction, barrel pillow deformation correction, lens deformation correction; powerful image analysis capabilities, can simultaneously measure absorbance and reflectance of two images, analyze sample material composition; static and dynamic images can be compared in real-time; provides functions such as setting tolerance for magic wand selection, full selection and inverse selection, saving and releasing selections, setting object properties, compositing objects onto images; offers direct measurement of straight lines and angles; automatically calculates perimeter, area, and other parameters of selected regions and annotates them; enhances image areas or the entire image, including contrast, brightness, exposure compensation, segmentation, histogram enhancement, feathering, sharpening, motion blur restoration, defocused blur restoration, etc.; includes genuine CD and software encryption dongle, USB plug-and-play.
