LISUN Integrating Spheres –After-sales Frequently Asked Questions (FAQ)

Q1：The big sphere can’t be openned.
A1：We put two screws to lock the sphere during the transportation to avoid opening. Please just remove these two screws.

Q2：How to disassemble the big integrating sphere into two parts to facilitate transportation.
A2：First of all, it is not recommended to disassemble and transport it, as this will easily stain the internal coating. If you have to, please remove all the large black hand screws to disassemble the big integrating sphere into left and right parts. NOTE: Do not remove any other kind of screws. During transportation, please be careful not to dirty the internal coating of the integrating sphere.

Q3：The installation direction of the sample.
A3：The integrating sphere holder base can be installed on the top or bottom of the integrating sphere. When installed at the bottom of the integrating sphere, all lamps should be installed with the emitting direction facing directly upward, as shown below:
On the contrary, if the holder base is installed on the top of the integrating sphere, all lamps should be installed with the emitting direction facing directly downwards.

Q4：How to maintain an integrating sphere.
A4：① The internal coating of the integrating sphere is very important, so you must wear white gloves whenever you are working inside the integrating sphere to avoid staining the internal coating of the integrating sphere.
② When the integrating sphere is not in use, keep it closed to prevent dust from entering. If dust gets in, use a blower to blow it out. Please do not use any contact materials to clean the inside of the integrating sphere, otherwise the coating may be damaged.
③ If the sample, etc. falls, causing a small area of coating inside the integrating sphere to peel off, please contact us. We can send you a small amount of paint free of charge to repair the peeling parts.

Q5：Install a 10W standard lamp in a 0.3m sphere, install the assistant lamp in a big sphere.

For ease of use and to minimize test errors caused by unnecessary accessories, when installing a 10W standard lamp into a 0.3-meter small integrating sphere, you only need to insert the bulb into the fixture in the small integrating sphere, as shown in the figure below:
