The Blisco BLS-107 Student Microscope is a newly introduced, high-performance laboratory instrument designed with a heavy-type, pressure die-casted monocular body for exceptional operational stability and balance. This advanced compound microscope features a straight optical tube with a mechanical length of 160mm ($\pm$ 1mm) that is completely inclinable up to a horizontal level of 90°, allowing users to customize their viewing angles comfortably. It is equipped with a dust-proof triple revolving nosepiece with positive click stops, allowing seamless transitions between high-precision 10x and 40/45x (SL) Achromatic objective lenses. The optical configuration incorporates a premium 10x wide-field eyepiece to provide a larger and more comfortable field of view.A major highlight of this model is its moveable substage illumination system, which features a bright-field Abbe N.A. 1.25 condenser and an iris diaphragm with a built-in swing-out filter holder that moves precisely up and down via a dedicated rack and pinion mechanism. Light control is further managed by a standard fork-mounted plano-concave mirror. The unit features an expansive 120mm x 120mm fixed square stage designed to natively accept an attachable mechanical stage, featuring integrated stage clips to secure specimens. Perfect focusing control is achieved through separate coarse adjustment knobs and highly sensitive, graduated fine focusing knobs. Each microscope comes complete with a duster, protective cover, and an instruction manual, all safely triple-packed across a thermacool box, a card box, and a solid outer wooden box.
