How to reduce uneven image caused by dot pattern

• - Open lens diaphragm slightly
• - Bring the object work into focus
• - When there is too much amount of light, adjust to increase the shutter speed of a camera
• - Adjust the light position (positioning outside of depth of field)
• - Adjust the amount of light (control reflection and shining)

How to prevent the influence by the disturbance light

• - Attach a sharp-cut filter to the lens (effective for red light)
• - Increase shutter speed of a camera and adjust dimmer volume
  (Open lens diaphram slightly and adjust to 50-70%)
• - Prevent disturbance light with a hood

How to prevent the influence by dirt and dust

• - Be careful of handling the light, and be sure that dirt, dust or finger prints do not get stuck on the surface of the light
• - Do not touch the dirt and dust by hand, and remove them by blowing air
• - Remove finger prints with fine-mesh, soft cloth
• - If the dirt is persistent, wipe it softly with diluted, mild detergent
