Laboratory Notice: Maintenance and Operation Manual for Stereoscopic Microscope

As a precision optical instrument, the maintenance quality of stereomicroscopescanAffects observation accuracy and equipment lifespan. To ensure that the equipment is always in good working condition, this guide is specially formulated to standardize the maintenance operation process.

1、 Daily use and maintenance

InBefore each use, use a dust-free soft cloth to wipe the appearance of the equipment, remove surface dust and stains, and prevent particles from entering the optical system. When placing samples, the movement should be gentle to prevent deformation of the stage due to impact, while ensuring that the samples are firmly fixed to avoid displacement and damage to the lens during observation. If the field of view is blurry during use, priority should be given to checking whether the eyepiece and objective lens are clean, rather than frequently adjusting the focal length. After use, it is necessary to promptly turn off the power, unplug the plug, cover it with a dust cover, and isolate dust and moisture.

2、 Special maintenance of optical components

The eyepiece and objective lens are the core optical components, and special care should be taken during maintenance. Special lens paper is required for cleaningwipe(It is strictly prohibited to wipe directly with alcohol),needAvoid scratching caused by back and forth friction. If there are stubborn stains on the surface of the lens, you can first let the cleaning agent dissolve the stains for a few seconds, and then gently wipe them. It is strictly prohibited to touch the lens with hands. Finger grease can affect the light transmittance and is difficult to clean. In addition, it is necessary to regularly check the connection between the objective lens and eyepiece to ensure that there is no looseness. If mold or damage is found on the lens, it should be stopped immediately and professional personnel should be contacted for repair.

3、 Mechanical structure maintenance

The mechanical components of the equipment, such as the focusing knob and the stage guide rail,Regular inspections are required andmaintain Wipe the surface of the guide rail with a dry cloth to remove dust and debris. If there is difficulty rotating the focusing knob, do not forcefully twist it. Check if there are any foreign objects stuck or add lubricating oil to relieve it.When encountering unsolvable problems, promptly contact professionals for guidance.The fixing screws of the stage need to be checked regularly to prevent loosening due to vibration, which may affect the stability of observation.

4、 Storage and environmental requirements

The equipment should be stored in a dry, ventilated, and sun free environment to avoid moisture causing mold on the lenses and rust on the metal parts. The ambient temperature needs to be controlled within 15-25 ℃, relative humidity not exceeding 60%. When not in use for a long time, it is necessary to power on once a month，Check if it can be used normallyAt the same time, it is necessary to stay away from areas with high levels of corrosive gases and dust to prevent damage to components.

Following the above maintenance standards can effectively extend the service life of stereomicroscopes, ensure the accuracy of observation data, and provide reliable support for experimental research.
