Optical design glass, filter glass and other documented optical material systems for windows, filters, substrates, discs and precision interfaces.

How to Read the Material Data

Compare the optical, thermal, chemical and supply-form characteristics of each material family, then match the grade to the finished component and operating environment.

Information Required for Material Review

  • Named grade or optical, thermal and chemical requirements.
  • Required form, thickness, dimensions and finished geometry.
  • Application environment and downstream process conditions.
  • Quantity, inspection records, cleaning and packaging requirements.

How to Choose

Choose the Material from Performance, Grade and Finished-Part Requirements

The category owns broad material-family and comparison terms. Named grades and distinct material families keep their own detail pages.

Start with the operating requirement

Use wavelength, temperature, thermal cycling, chemicals, dimensional stability and mechanical exposure to narrow the material family.

Compare named grades separately

Keep manufacturer, grade, test condition and source attached to each value instead of mixing family-level and grade-level data.

Confirm the starting form

Check sheet, plate, wafer, block, tube or rod availability together with thickness and usable blank size before finalizing the drawing.

Connect material to the finished part

The final selection must also support cutting, machining, polishing, cleaning, coating, inspection and packaging requirements.

Supply Forms

Confirm the Starting Form and Thickness

Available form and usable size must be confirmed for the named material and order.

Application Direction

Match the Material to the Service Environment

The application narrows optical, thermal, chemical, surface and process requirements.

Frequently Asked Questions

Selection and RFQ Questions for This Category

Use these answers to prepare the material, component, drawing and inspection requirements before quotation.

What is optical glass?

Optical crown and flint glasses are grade-controlled materials defined by refractive index, Abbe number, dispersion, transmission and chemical class. ANTGLASS supplies and processes N-BK7, K9/H-K9L, N-SF11 and related grades into windows, prisms and drawing-based optical components.

Which grades are included in Optical Crown & Flint Glass?

The category includes SCHOTT N-BK7 Optical Glass, K9 / H-K9L Optical Glass, SCHOTT N-SF11 Optical Glass. Each grade has a separate page so that values and sources are not mixed.

Which properties matter when selecting Optical Crown & Flint Glass?

Review wavelength or transmission, refractive properties where relevant, CTE, temperature, chemical durability, hardness, thickness, starting form, geometry and finished-surface requirements.

What products can ANTGLASS manufacture from Optical Crown & Flint Glass?

ANTGLASS supplies and processes these materials into Precision Optical Glass Windows, Optical Glass Prisms, Sensor & Machine Vision Glass Windows, Laser Windows, Custom-Shaped Precision Glass Parts and other drawing-based components.
