JF-6 Electronic Cover-Glass Laboratory Inspection
For an electronic cover-glass laboratory, the useful measurement question is often how a strengthened substrate’s stress changes with depth. JF-6 uses scattered light photoelasticity to measure the stress distribution of chemically tempered glass. The stated depth-of-layer range is DOL 10~6...Read more -
Selection Guide for Automotive Safety Glass Testing: Focus on Ghost Image Angle Measurement Solutions
Jeffoptics’s Solutions Vehicle safety and visual comfort rely heavily on the optical quality of laminated windshields and side windows. Modern automotive designs feature steeply raked windshields and head-up display (HUD) systems, making optical distortions increasingly noticeable to drivers. Amo...Read more -
Custom JF-2E Glass Measurement Workflow: Define the Change
A custom glass-measurement project becomes easier to define when the team can name the existing measurement task and the part of the workflow that prevents a useful result. JF-2E uses the optical waveguide effect to measure surface stress in chemically tempered and thermally tempered glass. The m...Read more -
JF-1A Solar-Glass Surface Stress Inspection Before Assembly
A solar-glass stress check is most useful when the quality team can identify the treatment, reach the intended surface and connect the observation to a specific lot decision. JF-1A is applied to measuring surface stress of thermally toughened and heat-strengthened glass. The measurement range is ...Read more -
AEM-01 Calibration and Edge-Stress Verification Guide
For a glass quality team, a changed edge-stress reading raises two questions: did the specimen change, or did the measurement conditions change? AEM-01 uses the photoelastic principle for non-destructive glass edge-stress measurement. Resolution is 1 nm or 0.1 MPa. A useful calibration and verifi...Read more -
How to Test Ghost Image Angle in the Camera View Zone for ECE R43 Automotive Glass Certification
Distorted vision in automotive windscreens creates severe safety risks, often causing driver misjudgments that can lead to hazardous road incidents. Modern vehicles rely heavily on advanced driver-assistance systems (ADAS) and head-up displays (HUD), making optical clarity inside the camera view ...Read more -
OWADMS-01 Lab Versus Production Station Evaluation
A windshield optical project becomes harder to specify when the station location is chosen before the measurement task. OWADMS-01 automatically measures optical angular deviation, binocular deviation, and optical wedge angle. The measurement range is 70 arcmin or 4200 arcsec. The useful first dec...Read more -
Analysis: How Jeffoptics High Quality GASP Surface Stress Gauge Ensures Compliance with ASTM C1279
Achieving structural reliability in architectural and industrial glass applications requires precise control over surface stress and edge strength. As engineering specifications tighten across global projects, compliance with international standards such as ASTM C1279—the standard test method for...Read more -
JF-6 Calibration and Method Verification Planning
A chemical-strengthening laboratory needs to know whether a changing stress profile comes from the glass or from the measurement process. JF-6 uses scattered light photoelasticity to measure the stress distribution of chemically tempered glass. The stated stress range is CS 0~2000 MPa. Method ver...Read more -
JF-2E Thermal Tempered Glass Stress Measurement
A portable stress meter is useful only when its measurement route matches the glass. JF-2E uses the optical waveguide effect to measure surface stress in chemically tempered and thermally tempered glass. JF-2E is a portable version with a 3.5-inch PDA and a 4000 mAh battery. For a laboratory comp...Read more -
Jeffoptics DSR Surface Stress Meter: Setting the Standard for EN12150-2 Glass Quality Assurance
Architectural glass safety relies heavily on precise compliance with EN12150-2, the European standard governing thermally toughened soda lime silicate safety glass. Achieving consistency requires rigorous monitoring of surface stress, fragmentation characteristics, and mechanical resistance. When...Read more -
JF-1A Surface Stress Checks for Glass Furnace Setup
A furnace setup trial needs evidence from the glass it produces. JF-1A is applied to measuring surface stress of thermally toughened and heat-strengthened glass. The measurement range is 15~400 MPa. For a process engineer comparing trial runs, it provides a portable route to a defined surface-str...Read more
