The most widespread optical material is considered to be clear optical glass. Lytkarino Optical Glass Factory manufactures about 200 types of clear optical glass that constantly are being developed and improved to meet the customer requirements. The broad assortment of clear optical glass allows in easy way to choose materials for different optical systems fabrication. More detailed information find here:
 clear optical finished glass
Our clear optical glass is used in a broad range of applications, i.e. in production of lenses, prisms, plates and other optical components used in viewing devices, measuring optical gauges, photo and projection equipment, visual and automatic systems of any devices that receiving, transmitting and transforming of optical emission as per the given law.
Clear optical glass is supplied in forms of blanks: pressings, discs and other forms. LZOS Company is able to supply polished optical components (lenses, prisms, plates, wedges, etc). More detailed information about form and quality of supplied glass find in pages:
 blanks made by glass melts method
Clear optical glass is manufactured by three series depending on operational conditions of optical devices, they are 0, 100 and 200:
- Glasses series 0 is used for blanks of optical components of devices and equipment operating in usual conditions.
- Glasses series 100 is used for manufacturing of optical parts, devices and equipment operating in condition of advanced ionization radiation.
- Glasses series 200 is used for manufacturing of optical parts, devices and equipment operating in condition intensive and long-term exposure of ionization radiation.
Almost each optical glass type has its analogue but with special properties of resistance to gamma irradiation and ionization, that is specified in clear glass catalogue too.
GLASS CLASSIFICATION SYSTEM
Depends on refractive index nе and Abbe value vе the clear optical glasses are classified by groups that naming and designating according to Russian standards are given below:
| glass group name | short designation | | light crown | LK | | phosphate crown | FK | | dense phosphate crown | TFK | | crown | K | | barium crown | BK | | dense crown | TK | | extra dense crown | CTK | | special (witn special dispersion path) crown | OK | | crown flint | KF | | barium flint | BF | | dense barium flint | TBF | | light flint | LF | | flint | F | | dense flint | TF | | extra dense flint | CTF | | special (witn special dispersion path) flint | OF | The glasses of one group but having different chemical composition are given various types consisting of letters accepted as for the glass of this group and sequential number.
In addition the glass types are auxiliary designated by six-figured code consisting of two groups of figures divided by scribe mark. The first three figures are three ten-digit numbers of refractive index, the second three figures are Abbe value multiplied by 10 times.
For customers convenience our clear optical glass is referenced in the table below by types with glasses of firms Schott Glasswerke, Mainz, Corning France и Hoya.
Additional information about glass properties and characteristics measurements find in page: [SUPPLEMENTARY DETAILS]
[about optical glass properties] Parameters and detailed data about clear optical glass are given in page: More accurate complete details with all comparable parameters are presented in printed OPTICAL GLASS CATALOGUE of LZOS, JSC that you can procure separately.
Particularly watch out for OK-4 type glass with specific course of dispersion that can be used like a substitute of crystal material CaF2.
