Ball lens are highly transparent spheres made of optical glasses.They are used as fiber interconnects in telecom and expanded beam connectors.Large ball lenses have been successfully used as collectors in LED lighting systems and medical devices.They have high coupling efficiency and should be much easier to align than traditional lenses due to its physical shape.Fused silica balls are ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Sapphire balls has superior optical transmission qualities. Ruby Balls are easier to see and therefore easier to handle for physical applications.
Half ball(hemispherical)lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.

2. Daily cleaning Wipe the floor in the direction of the floor with a vacuum cleaner or with a wrung mop or a damp cloth. Do not use a damp cloth or steam cleaner. Do not rinse with water or use a dryer.
3. Cleaners Do not use laminating cleaners or sand cleaners when removing stains on floor surfaces. Use chemical cleaners with caution. Do not strike, hit, scratch the floor, or use polish or sandpaper on the floor to avoid accidental damage to the surface wear layer. If you accidentally sprinkle water or various liquids on the floor, wipe it dry as soon as possible.
4. When you are away from the humidity, you should pay attention to closing the water and closing the window to avoid accidental flooding and rain.
5. Humidity Control Humidification measures should be taken when the indoor humidity is lower than or reaches 40%. When indoor humidity reaches 100%, ventilation should be conducted.
6. Protective measures Table and chair feet are best equipped with felt mats, walking office chairs should be installed with soft walking wheels. Do not place the heavier furniture centrally. When moving on the floor, lift the furniture. Do not push or pull directly on the floor.

Care of wood floors should pay attention to 6 issues
1. Ventilation and Drying After installation, laminate flooring should be ventilated and dry for 24 hours until the glue cures.
