GOST 23136-93 PDF

Full title and description

GOST 23136-93 — «Материалы оптические. Параметры» (English: Optical materials. Parameters). The standard defines the primary parameters, categories, classes and groups used to specify and accept inorganic optical materials (colorless and colored optical glasses, glasses with special optical properties, crystals, polycrystalline and glass‑ceramic optical materials).

Abstract

GOST 23136-93 establishes terminology, measurement parameters and classification schemes for optical materials used in optics and photonics. It specifies parameters such as refractive index, optical homogeneity, birefringence, spectral attenuation (absorption), swirl‑like defects, bubble content, and provides classification by categories, classes and groups as well as recommended formats for digital recording of parameter data. The document includes recommended appendices with guidance on homogeneity categories and digital encoding of parameters.

Scope

The standard applies to inorganic optical materials — including colorless and colored optical glasses, glasses with special optical properties, single crystals, polycrystalline and glass‑ceramic materials — and establishes the measurable parameters, limits and classification rules used for specification, ordering and quality control of these materials in optical manufacture and research.

Key topics and requirements

• Definition and list of principal optical parameters: refractive index and its dispersion, optical homogeneity, birefringence, spectral absorption (attenuation), scattering and related characteristics.
• Classification system: categories, classes and groups for each parameter (numerical limits and allowed defect levels for ordered categories).
• Criteria and limits for swirl‑like defects, bubble content and other inclusions specific to optical quality. (xn-----6kcbaeeywflm3c1andac1au8v.xn--p1ai)
• Requirements and recommended measurement references (normative references to related GOST test methods for birefringence, bubble content, attenuation, color measurement, etc.).
• Recommended formats for recording parameter values and for digital encoding of quality parameters for computer processing.

Typical use and users

Used by optical‑glass and crystal manufacturers, suppliers of optical blanks, optical component and lens manufacturers, metrology and QC laboratories, research institutions in optics and photonics, and procurement/specification engineers who define material acceptance criteria for lenses, windows and infrared/visible optical components. It is also a reference for national standards committees and technical committees working on optical material classification.

Related standards

Normative references and closely related documents include the earlier edition ГОСТ 23136-78 (replaced), and multiple test‑method standards referenced within the text (for example standards on determination of birefringence, bubble content and optical attenuation). In Russia the document has been superseded by the national standard ГОСТ Р 71952-2025 (Optics and photonics — Optical materials. Basic parameters and classification), which entered into force 1 January 2026 by Rosstandart order.

FAQ

Q: What is this standard?

A: GOST 23136-93 is a national/inter‑state standard titled "Материалы оптические. Параметры" (Optical materials. Parameters) that defines parameters and classification rules for inorganic optical materials.

Q: What does it cover?

A: It covers measurable optical material parameters (refractive index and dispersion, optical homogeneity, birefringence, spectral attenuation/absorption, bubble and inclusion limits, swirl‑like defects), the classification of these parameters into categories/classes/groups, and recommended methods and record formats for specifying material quality.

Q: Who typically uses it?

A: Manufacturers and suppliers of optical glass and crystals, optical‑component producers, quality‑control and metrology labs, optics researchers, and procurement/specification engineers in optics and photonics.

Q: Is it current or superseded?

A: As of 1 January 2026 GOST 23136-93 was formally ceased for application in the Russian Federation and replaced by the national standard ГОСТ Р 71952-2025 (Optics and photonics. Optical materials. Basic parameters and classification) by Rosstandart order dated 17 July 2025. For projects in Russia and for up‑to‑date procurement, users should refer to ГОСТ Р 71952-2025.

Q: Is it part of a series?

A: The standard is part of the optics/photonic family of standards (OKС 37.020) and references several related GOST test‑method and material standards; historically it replaced ГОСТ 23136-78 and was later superseded by ГОСТ Р 71952-2025.
