1. Visual and Mechanical Inspection • Inspect the overall microscope condition for damage, wear, or missing components. • Check mechanical parts, including focus knobs, stage controls, and mechanical stage movement, for smooth operation. • Inspect all adjustment mechanisms, locks, and tension controls for proper function. • Verify the stability of the base, arm, and head assemblies. 2. Optical System Cleaning and Inspection • Clean all accessible optical components (eyepieces, objectives, condenser, mirrors, and filters) using approved lens cleaning materials. • Check optical surfaces for scratches, fogging, or contamination. • Inspect objective turret alignment and secure mounting. • Verify condenser alignment and iris diaphragm function. 3. Illumination System Check • Inspect the light source housing and optics. • Check bulb or LED condition, brightness, and color temperature. • Verify intensity control and illumination uniformity. • Inspect the power supply, cord, and connectors for wear or damage. 4. Functional and Alignment Verification • Verify optical alignment and image centering. • Confirm parfocality and focus accuracy between objectives. • Test stage travel limits and smoothness of movement. • Confirm condenser centering and Kohler illumination (if applicable).
