ANTGLASS supplies and processes SCHOTT B 270 Glass for optical, electronic, laboratory and industrial components made to customer drawings.
Material Overview
B 270: Super-white modified soda-lime crown glass. The material system is described as Super-white modified soda-lime crown glass. Selection begins with the exact grade, wavelength or optical function, thermal and chemical environment, starting form, finished geometry and inspection method. The material record is kept separate from the finished-part drawing so that grade data and manufacturing requirements remain traceable.
Applications associated with this material include Display covers, instrument windows, lighting, microscopy, coated substrates. ANTGLASS uses the approved material and drawing to manufacture blanks and finished parts rather than treating a published material property as a universal component guarantee.

Design Rules for a Manufacturable RFQ
- Specify the exact material grade or the required optical, thermal and chemical properties.
- Dimension critical surfaces, edges, holes, slots and datums separately on the drawing.
- Identify optical, sealing, bonding, coated and cosmetic zones before quotation.
- Match inspection methods to the functional tolerance and surface requirement.
- State prototype and production quantities together with cleaning and packaging needs.
Quality Risks and Inspection
Keep material identity, geometry, surface requirements and final operating conditions under one controlled drawing and inspection plan.
- Material identity and source documentation
- Dimensions, thickness and feature position
- Edge chips, cracks and surface condition
- Cleaning, orientation and protective packaging
Applications and Product Connections
- Display covers
- instrument windows
- lighting
- microscopy
- coated substrates
Material Comparison and Alternatives
Compare SCHOTT B 270 Glass with B 270 for controlled optical quality, N-BK7 for imaging, borosilicate for heat and chemical duty.. Substitution should preserve the functional wavelength, refractive or spectral behavior, thermal expansion, temperature range, chemical durability, mechanical behavior, starting form and component cost.
