Key equipment and testing capabilities
01 Spectral Test
UV-VIS-NIR spectrophotometry for transmission, blocking OD, and bandwidth.
02 Geometry and surface shape
Interferometry for flatness; parallelism, thickness, and dimensional checks (AQL or 100% by need).
03 Appearance quality
Microscope & optical bench for scratch-dig; cleanliness, bubbles, and stress mark inspection.
Quality control system
01 IQC
Grade/lot verification, dimensional/visual sampling, baseline spectral checks when required.
02 IPQC
SPC at critical steps (thickness/parallelism/thermal profile/screen consistency).
03 OQC
Complete inspection of finished products, and sampling inspection when shipped
