Anti-Reflective Coated Optical Achromatic Lens for Projection Optics

Anti-Reflective Coated Optical Achromatic Lens for Projection Optics

Material & Core Properties:
Our achromatic lenses are meticulously constructed using a bonded doublet design, combining two optical elements made from glasses with different dispersion properties, typically crown (e.g., H-K9L/BK7) and flint glass.

• Chromatic Aberration Correction: This dual-element design brings two primary wavelengths (commonly red and blue) to a common focus, dramatically reducing color fringing and improving overall image sharpness compared to a simple singlet lens.

• Broadband Anti-Reflective Coating: Multi-layer AR coatings are applied to all air-glass surfaces. These coatings are optimized for the visible spectrum (e.g., 400-700nm), minimizing reflection losses to typically less than 0.5% per surface. This maximizes light throughput, enhances contrast by reducing veiling glare, and improves system efficiency.

• High Precision Mounting: Elements are centered, edged, and bonded with high accuracy to ensure optimal optical alignment and performance, housed in durable black anodized aluminum barrels for secure integration.

Primary Function:
The core function of this lens in projection optics is high-fidelity image formation and transmission. It is specifically designed to:

• Produce a Color-Accurate, Sharp Focus: By correcting chromatic aberration, it ensures that all color components of the image are focused at the same plane, resulting in crisp, high-contrast projections without colored halos.

• Efficiently Transmit Light: The AR coating ensures minimal light is lost to reflections, which is critical for maintaining bright, vibrant projections and enabling the use of lower-power, more efficient light sources.

Key Applications:

• Digital Projectors: Essential in DLP (Digital Light Processing), LCD (Liquid Crystal Display), and LCoS (Liquid Crystal on Silicon) projector lens assemblies for home cinema, business, and education.

• Professional Display & Simulation: Used in high-end flight simulators, planetariums, and large-format display systems where color accuracy and edge-to-edge sharpness are paramount.

• Photographic & Cine Projection: A key component in high-resolution digital cinema projectors and photographic enlargers.

• Optical Measurement & Inspection Systems: Integrated into systems requiring precise, aberration-free imaging for analysis and measurement.
