Inspection and Measurement


LaserStates has professional inspection instruments to assure the quality.

Please note, Inspection can't create good products. Only control each process well could create good products.

Standards

LaserStates is very familiar with ISO10110, DIN3140 and MIL standards. We made training documents for the operators and inspectors. Everyone could process and inspect based on the standards.
 

Dimension Measurement

 Besides the calliper, micrometer and thickness gauge, the projector and microscope could be used in measure the dimension, geometric tolerance and chamfers.


Angle Measurement

 Goniometer is used to measure the angle of the prisms.

 Centering Measurement
 

Centering Device is used to measure the centration of the lens, or adjust the centration of the acromatic lens during the cementing
 

Surface Quality
 

According different standards (for example DIN3140/ISO10110/MIL-O-13830A), using different methods to inspect surface quality. LaserStates has rich experience to assure the surface quality.
 

 Surface Figure

LaserStates has 4" ZYGO GPI XP/D which could measure Surface figure and radius of Cylindrical surface and Spherical Surface, Parallelism for Plano surfaces.

 

Measure Area Note
Surface Flatness  Plano, Spherical Surface and Cylindrical Surface
Radius of Curvature Spherical Surface and Cylindrical Surface
Transmitted Wavefront Plano, Spherical and Cylindrical
Angle Parallelism of plano surfaces, 90°angle accuacy of RAP
Homogeneity Homogeneity of polished material

Coating  

 LaserStates has 1 PE 750 Spectrophotometer to control the coating quality.
