Maintenance of optical microscope
Maintenance of equipment placement and use environment
▪Moisture-proof: When the air is too humid, optical lenses are prone to mold and fog; mechanical parts are prone to rust after being damp. Usually the microscope room should keep the humidity below 65%, and a dehumidifier should be installed indoors in humid areas.
▪Temperature control: In order to avoid thermal expansion and contraction of the lens from degluing and falling off, the room temperature of the microscope room is recommended to be maintained at 20-24°C.
▪Dust-proof: Dust falling on the surface of optical components not only affects the passage of light, but also generates large stains after being enlarged by the optical system, which affects observation. Dust and sand falling into the mechanical parts will also increase wear and tear, which is also very harmful. Therefore, the microscope room should be kept clean, and the microscope should be covered with a dust cover when not in use to prevent dust from falling.
▲Parts prone to dust accumulation
▪Anti-corrosion: Microscopes cannot be placed together with corrosive and highly volatile chemical reagents, such as sulfuric acid, hydrochloric acid, strong alkali, etc.
▪Shockproof: The optical system and mechanical system of the microscope have been precisely calibrated. During use and storage, it must be shockproof. At the same time, attention should be paid to avoid direct sunlight and air conditioning directly blowing the microscope to ensure its inherent high performance.
▪Voltage stabilization: The fluctuation of the power supply voltage of the microscope room should not exceed ±10% of the normal voltage. In areas where the voltage is unstable, a stabilized power supply should be installed to protect the microscope system from damage.
Optical System Maintenance
▪Do not touch optical parts with hands
▪The lens cleaning paper is used for oil lens cleaning, please use absorbent cotton swabs for dry lens cleaning
▪After the oil lens is used, use a clean and soft professional lens cleaning paper dipped in absolute ethanol to gently wipe the oil objective lens in a spiral gradual manner;
√ Pay attention to the two sides of the lens cleaning paper, the texture is different: one side is rough, and the other side is smoother, use the smoother side for cleaning. It is generally not recommended to wipe directly with dry lens cleaning paper, as it may scratch the lens.
▪If there are more stubborn stains or dust, first use the ear cleaning ball to blow away the larger and harder dust, and then wipe it with a long-fiber absorbent cotton swab or a clean fine cotton cloth dipped in absolute ethanol, so as to avoid scratching by the larger and harder dust particles The lens affects the observation effect.
▪How to wipe the eyepiece and objective lens
√ Preparation: Dip the top of a long-fiber absorbent cotton swab with absolute ethanol
√ Eyepiece: Starting from the central part, use a spiral progressive method to gently and gradually rub to the edge
