Eyepiece and objective lens:
A) High eye point flat field eyepiece PL10X, with a line of view of 18mm, provides a wide and flat viewing space, and can be installed with various micrometers
B) Long working distance professional achromatic metallographic objective lens
C) No cover glass slide design, excellent image quality
● Lighting system: Drop type Kola lighting with anti reflection structure designed to effectively prevent interference from reflected light, resulting in clearer images and better field of view contrast
Adopting adaptive wide voltage 100V-240V, 6V30W halogen lamps, with adjustable filament center and continuous adjustable light intensity, providing more sufficient illumination and effectively improving image quality
● Stage: A composite mechanical mobile platform with low hand position coaxial adjustment, and a flat platform of 180mmx145mm attached to the mechanical platform, but suitable for placing larger samples
● Attachment
A) Four types of color filters, yellow, green, blue, and white, can be added to the illumination path to provide different chromaticity colors for observing various sample roots
B) Polarizing and analyzer lenses can be added to the illumination light to achieve polarized observation
C) The polarizer can be adjusted by ± 25 °, which can effectively adjust the orthogonal state or field of view contrast
