Black Spots

Black Spots

Black Spots are cosmetic blemishes that may originate from fixed particles inside the I2 tube or in the fiber optic. Small size black spots in the I2 tube are inherent to the manufacturing process and do not affect the performance or reliability of the device.

The amount of black spots has a direct consequence on the unit price of an I2 tube (the more spot the less costly) but has no influence on its actual low light or high light level performance.
