Description
 
Product Description

          The company can provide H-K9L, H-K9LGT high-uniformity bulk optical glass, which has the advantages of good optical uniformity and stress uniformity, small stress birefringence, etc., and is used in astronomy, aerospace, industry and other fields.

Optical uniformity

           Optical uniformity refers to the degree of uniformity in the refractive index of each part of a piece of glass. For optical glass used in high-precision optical systems, the refractive index change in each glass must be small, that is, the optical uniformity is good. The optical uniformity index should be determined according to the application and the final geometric size of the optical element.
           Optical uniformity is represented by the maximum value Δnmax of the refractive index difference between various parts in a piece of glass.Measured according to the test method specified in GB/T7962.2-2010, divided into 4 categories, see the table below.
 

CategoryΔnmax
H000.5×10-6
H01×10-6
H12×10-6
H25×10-6
H310×10-6
H420×10-6

Stress uniformity

            Stress uniformity refers to the degree of uniformity of stress in each part of a piece of glass. The stress uniformity specification should be based on the application and the final geometry of the optic.
