Custom Microscope Objectives for High-Precision Imaging

Microscope objective lenses are the heart of any advanced microscopy system. At Yighen Ultra Precision, we design and manufacture custom microscope objectives tailored for demanding applications in medical diagnostics, life sciences, semiconductor inspection, and scientific research. Whether you're building a fluorescence microscope, an IR/NIR system, or an OEM biological instrument, our team delivers performance-optimized objectives—designed from scratch or reverse-engineered to meet your unique optical and mechanical specifications.

🔍 Types of Microscope Objective Lenses We Offer

We support a wide range of objective lens microscope configurations, each carefully engineered to optimize resolution, working distance, and spectral performance:

• Achromatic Objectives – Budget-friendly options for basic laboratory and industrial imaging.

• Plan Achromat Objectives – Minimize field curvature, ideal for flat-field imaging.

• Plan Apochromatic Objectives (Plan APO) – Superior correction of chromatic/spherical aberrations; excellent color fidelity.

• Super Apochromatic Objectives (SAPO) – Ultra-high numerical aperture for critical fluorescence, DIC, or confocal imaging.

• Custom Infinity-Corrected Objectives – Designed for integration into OEM systems with variable tube lengths or beam paths.

• Long Working Distance (LWD) / Ultra-Long Working Distance (ULWD) – Ideal for microfluidics or inspection over thick substrates.

📌 All objective types are available in dry, water immersion, and oil immersion formats.

💡 Applications of Our Microscope Objectives

Our custom microscope objectives are trusted by clients in:

• Medical Imaging & Pathology

• Life Science Research (fluorescence, phase contrast, confocal)

• Semiconductor Wafer Inspection

• Biochip & Lab-on-Chip Systems

• AR/VR Display Pixel Inspection

• UV/VIS/NIR Spectral Applications

🔧 Custom Design Services

If your application demands beyond off-the-shelf capabilities, Yighen’s optical engineering team can:

• Design for specific cover glass thicknesses (e.g. 0.17mm ±0.01mm)

• Optimize for custom wavelengths (from UV to SWIR)

• Configure non-standard magnifications (e.g. 1.5X, 3.3X, 15X, 60X)

• Meet unique mechanical envelopes and mounting constraints

• Design for large field-of-view (FOV) or high numerical aperture (NA)

With in-house ZEMAX, CODE V, and SolidWorks workflows, we ensure tight opto-mechanical integration for your system.

🏭 Manufacturing Process & Metrology

From prototype to volume delivery, Yighen maintains full control of the design → processing → coating → assembly → testing chain.

🔹 Key Capabilities:

• Ultra-precision grinding and polishing (Ra < 2nm, P-V < 0.1μm)

• Sub-nanometer surface roughness for high-NA elements

• Cleanroom assembly with active alignment

• MTF and interferometric testing (double-pass, collimator-based)

• Coatings for anti-reflection (AR), fluorescence, NIR/SWIR, polarization control

We follow strict ISO9001 and ISO13485 processes to ensure high repeatability, even for small-batch optical assemblies.
