Product Description
- Hemispherical Design: Manufactured by precision cutting a spherical (ball) lens into a hemisphere, enabling easier mechanical mounting and alignment compared to full ball lenses while preserving high-NA performance.
- Optical Advantage: The hemispherical geometry minimizes spherical aberration when coupling light from a point source or into optical fibers, making it ideal for compact and high-efficiency optical systems.
Applications
- Fiber Coupling: Efficient coupling for UV–NIR light sources and detectors
- Microscopy: High-NA illumination and collection optics
- UV & VIS Optics: Suitable for spectroscopy, fluorescence, and imaging systems
- Laser Systems: Beam focusing and collimation for UV and visible lasers
- Optical Sensing: Compact coupling optics for sensors and photodiodes
Substrate Benefits – Fused Silica
- Broad Spectral Transmission: Excellent performance from deep UV (~180 nm) to NIR (~2.5 µm)
- Low Thermal Expansion: High dimensional stability in varying temperature environments
- High Laser Damage Threshold: Ideal for high-power and pulsed laser applications
- Low Autofluorescence: Critical for UV and fluorescence-based systems
Shape Optics Hemispherical (Half-Ball) Fused Silica Lenses offer high numerical apertures, outstanding UV–NIR transmission, and excellent thermal and optical stability. Their hemispherical form factor simplifies mounting while delivering superior coupling efficiency, making them a reliable choice for fiber coupling, microscopy, UV optics, and laser-based systems. Optional anti-reflection coatings are available to further enhance transmission for specific wavelength bands.
