OPTICAL GLASS
Catalog
We catalogue our Gost's glass collection: that relate to a glass-group, glass-type and glass-code. Our catalog presented the optical glass grades that improved index-number tolerance, abbe-number tolerance etc. The standard quality (ST), extra standard quality was presented too. We recommend the standard supply forms as follows: Block (BLK), Blank (BLN), Reheated-Pressings (RP), Direct-Pressings (DP) ... Element (ELT).
Data
Our glass data is standard specifications for 120 optical glass type. The glass data has been measured and listed in the specification. The index-number was measured at 14 standard spectral line, the transmittance at 4 standard spectral line. Other glass data has been calculated and printed in the specification: abbe-number, dispersions etc: thermic, chemic, mechanic data; standard material defects that relate to the raw, unprocessed glass (slab, strip) also more info for masters.
Datasheet
Our datasheet is standard specifications for each optical glass type, which point standard optical data at the glass material. Also we send you the datasheet with each our delivery.
Test-Report
We send you a
standard test-report to delivered glass. The additional measurement to standard
certificate should be ordered specially.
Table
The table
has compared optical glass type in Ukraine glass (Gost) close to Germany
glass (Schott) and Japan glass (Ohara). We compare optical glass for
index-number (nd) and abbe-number (Vd). If index-number are equal or
deviation nearby 0.001, this glass was specificated as is equivalent and/or
close in Gost's glass. The equivalent requirements for your optical design
should be determined by your qualified optical expert.
