The Blisco BLS-105 Student Microscope is a newly introduced, high-precision laboratory instrument built with a heavy-type, pressure die-casted monocular body that ensures excellent structural stability and balance. This advanced student scope features a straight optical tube with a mechanical length of 160mm ($\pm$ 1mm) that is completely inclinable up to a horizontal level of 90° for customized ergonomics. Outfitted with a dust-proof triple revolving nosepiece featuring positive click stops, it offers quick changes between high-grade 10x and 40/45x (SL) Achromatic objective lenses. The optical layout relies on a 10x wide-field eyepiece to maximize field view comfort.For superior illumination control, the instrument is engineered with a fixed-type bright-field Abbe N.A. 1.25 condenser and an integrated iris diaphragm equipped with a built-in swing-out filter holder. Natural light collection is handled by a standard fork-mounted plano-concave mirror. The fixed square stage spans an expansive 120mm x 120mm area designed specifically to accommodate an add-on mechanical stage, holding slides tightly in place using integrated metallic stage clips. Focusing is handled with expert precision via separate coarse and highly sensitive graduated fine adjustments. Each unit ships complete with a protective duster, storage cover, and user instruction manual, neatly packed in a double thermacool box, card box, and an additional robust wooden box configuration.
