Precision Glass Pressing
See how custom pressed glass components are precision formed for lighting applications.
✦ Concentric stepped rings define the visible Fresnel lens structure
✦ Low profile circular form provides a compact glass component
✦ Borosilicate glass forms the body of the stepped lens
✦ Frosted surface treatment gives the lens a translucent appearance
✦ Perimeter rim surrounds the concentric relief of the lens
A Frosted Fresnel Lens with Concentric Glass Steps
Concentric stepped rings define this circular borosilicate Fresnel lens and distinguish it from grid patterned designs.
A frosted sandblasted finish and low profile rim complete the component geometry.
May suit spotlight development; confirm custom optical requirements, focal length and seating geometry with the intended assembly.
Concentric stepped rings span the circular glass body. The optical prescription should define the detailed ring geometry and intended focal behavior.
The outer diameter is 120 mm and height is 13 mm. Ring profiles, seating dimensions and tolerances require a detailed optical and mechanical drawing.
The design has a frosted sandblasted finish with concentric relief. Define the final surface appearance with an approved sample.
State the focal length, tolerance and measurement conditions in the optical specification. Verify those requirements for the exact lens and light source configuration.
Check lens seating, retention, operating conditions and beam requirements in the intended spotlight. A lighting illustration does not establish optical performance.
Each size needs its own confirmed drawing and optical requirements. Keep size variants within a shared family when their structure and procurement intent are the same.
