Concave Glass Lens
Concave Glass Lenses (Diverging Optics)
Concave glass lenses (including plano-concave and bi-concave optical geometries) are precision optics characterized by inward-curving surfaces, designed to diverge collimated incident light rays and project virtual images.
Functions:
Delivers negative focal length performance to expand light beams, increase system focal distance, and correct spherical aberration in multi-lens optical assemblies. Engineered from optical-grade glass to maintain high broadband transmission, low distortion, and exceptional thermal stability.
Applications:
Laser beam expanders
Optical projection engines
Optical instrument eyepieces
Specialized illumination beam-shaping modules.
Automated Optical Inspection (AOI) imaging systems
Information and Notes
1. Custom optical coatings—including Anti-Reflective (AR) coatings, High-Reflection (HR) coatings, and bandpass spectral coatings—are available upon request to reduce stray reflection and optimize beam transmission.
2. Custom focal lengths, center thicknesses, edge tolerances, outer diameters, CNC profiling, and chamfering are fully customizable to meet specific OEM system integration needs.
3. Website specifications are provided for reference only. Final production and delivery comply with mutually agreed engineering specifications and actual physical products.
