Engineering FAQ

FAQ About Custom Optical Lenses and Precision Optical Glass Lenses

What materials are used for visible and UV optical lenses?

Common choices include BK7/H-K9L optical glass, fused silica and sapphire. Selection depends on wavelength, thermal load, mechanical exposure and coating requirements.

When should I choose BK7 optical lenses?

BK7 is often selected for visible optical systems that require stable transmission, practical processing efficiency and controlled cost for prototype or repeat production.

Why use fused silica lenses for UV applications?

Fused silica offers UV transmission, low thermal expansion and stability for UV detection, UV LiDAR ranging and semiconductor inspection optical paths.

Are sapphire optical lenses suitable for harsh environments?

Sapphire provides high hardness, abrasion resistance and chemical stability, making it useful for exposed or mechanically demanding UV and visible optical assemblies.

Can Felix Glass manufacture plano-convex and plano-concave lenses?

Yes. Plano-convex, plano-concave, biconvex, biconcave, meniscus and aspherical lens forms can be reviewed against drawings and optical requirements.

Can custom aspherical lenses be produced from 3D models?

Aspherical lens projects can be evaluated from drawings, CAD files or 3D models, including radius, sag, clear aperture, surface quality and inspection method.

What coating options are available for precision optical lenses?

Available coating options include visible AR coating, UV AR coating, HR high-reflective coating and DLC hard protective coating when compatible with the selected substrate.

Can these lenses be used in medical diagnostic imaging?

BK7 and fused silica lenses are commonly used in visible medical imaging and illumination systems, with ISO13485 production standard support available when required.

Are ZnSe or ZnS infrared lenses included on this page?

No. Thermal infrared ZnSe/ZnS lenses belong to the Infrared Optics product group so visible and UV optical lens search intent remains clearly separated.

What specifications should be included in an RFQ?

Please provide material, diameter, center thickness, radius or focal length, surface quality, coating band, quantity, drawing file and application wavelength.

Can focal length be inspected before shipment?

Focal length inspection can be arranged according to the project requirement, together with dimensional, surface and transmission-related inspection items.

Does Felix Glass support prototype and mass production?

Yes. Prototype review and repeat production can be arranged after material, tolerance, coating and inspection feasibility are confirmed.

What tolerance range can be customized?

Dimensional and optical tolerance depends on lens size, curvature, material and process route. Drawing review is required before confirming production limits.

Can optical lenses be supplied with inspection reports?

Inspection report support can be provided according to the purchase specification, including dimensional checks, optical testing and coating-related records when required.
