Precision Achromatic Doublet Lenses for Color-Corrected Imaging
Chromatic Aberration Correction | High-Resolution Focus | OEM Custom Integration
- Superior Color Correction: Expertly cemented using two carefully matched optical glasses (typically a low-dispersion Crown glass and a high-dispersion Flint glass) to bring two distinct wavelengths into the exact same focal plane, completely eliminating color fringing.
- Maximized Image Sharpness: Significantly reduces spherical aberration compared to standard singlet lenses. This results in ultra-crisp, high-contrast images, making them the superior choice for critical imaging relays and precision laser focusing.
- Optimized for Machine Vision: The ultimate imaging solution for Automated Optical Inspection (AOI), color-sensitive barcode scanning, and multi-spectral industrial metrology where spatial accuracy and true-color reproduction are non-negotiable.
- 100% Export Compliant: Engineered exclusively for commercial and industrial instrumentation. Completely Germanium-free and strictly tailored for civilian applications, ensuring a highly stable, restriction-free global supply chain for your B2B manufacturing needs.

Product Overview
Eradicating Optical Distortion
When white light passes through a standard single lens, different colors focus at different distances—a flaw known as chromatic aberration. Our Achromatic Doublet Lenses solve this by utilizing a sophisticated two-element cemented design. By canceling out optical dispersion, these lenses ensure that your automated vision systems capture razor-sharp, color-accurate data across the entire visible and near-infrared spectrum.
Maximized Photon Throughput
To guarantee peak optical efficiency in your specific operating environment, our doublets are available with specialized Broadband Anti-Reflective (BBAR) coatings. These multi-layer dielectric coatings drastically reduce surface reflections, eliminating ghost images and maximizing signal strength for your high-speed CMOS and CCD sensors.
Reliable, Ready-to-Integrate Optics
We understand that continuous B2B production relies on a predictable supply chain. We deliver globally compliant, tightly toleranced optical components directly to your factory floor or third-party integrators. Edges are carefully chamfered, and centering is strictly controlled to guarantee a perfect drop-in fit for your complex optomechanical lens barrels.
Application & Engineering Integration
Figure 1: Achromatic Doublet Reflectance (BBAR Coated)
Demonstrates exceptional anti-reflective performance with an average reflectance of < 0.5% across the visible spectrum, effectively eliminating ghosting and maximizing contrast for complex imaging systems.
Metrology Analysis & Application Fit
- Target Wavelength: Broadband capability spanning from the Visible (VIS) to the Near-Infrared (NIR) spectrum.
- System Integration: Ideal for use as objective lenses, imaging relays, or collimators. For optimal performance with infinite conjugate ratios, the more convex surface (usually the Crown glass side) should face the collimated beam or infinite light source.
- Primary Applications:
- High-resolution Machine Vision and AOI lenses.
- Fluorescence microscopy and biomedical instrumentation.
- Telescope objectives and complex multi-lens imaging assemblies.
- Broadband laser beam manipulation.
