This unit uses a lens and mask to mask the beam that passes through the integrating sphere opening. The minimum beam diameter is about 1 mm. It requires a sample base plate integrating sphere unit at the same time.
Note: For UV-2600 series, MPC-2600A and BIS-3100 sample base plate integrating sphere set is separately required.
For UV-3600Plus series, MPC-603A and BIS-603 sample base plate integrating sphere set is separately required.
For SolidSpec series, BIS-3700/3700DUV is separately required.
