Projection Lenses – Custom Design & Manufacturing by Yighen

At Yighen Ultra Precision, we design and manufacture custom projection lenses tailored for high-performance imaging systems—whether it's for DLP, LCD, or LCoS projection, or new-generation laser display systems. Our projection optics offer excellent resolution, low distortion, and uniform brightness, all optimized for your system’s throw ratio, wavelength, and mechanical integration.

🛠️ Whether you need a short-throw projection lens, zoom optics, or a complete optical module, we help you turn complex design needs into manufacturable products.

🔍 What is a Projection Lens?

A projection lens is a key component in display systems, used to magnify and project an image onto a screen or surface. Projection lenses typically consist of multiple lens elements, often integrating aspheric surfaces, low-dispersion materials, and AR coatings to ensure minimal optical aberration.

There are two major types:

• Fixed-Focus Projection Lenses: Optimized for a specific throw distance.

• Zoom Projection Lenses: Provide variable focal lengths and flexible image size control.

🔬 Typical Applications of Projection Lenses

• Home and professional projectors (LCD, LCoS, DLP)

• Head-Up Displays (HUD) in automotive AR

• Pico projectors and mobile embedded displays

• Structured light and 3D mapping

• Medical imaging projection modules

• VR/AR wearable displays

• Simulation & training systems

🛠️ Custom Projection Lens Design Process

Yighen supports both preliminary designs and fully custom projection lenses. Whether you're enhancing an off-the-shelf product or starting from a blank sheet, our optical design team provides:

1. Application Definition
   You define throw ratio, screen size, projection distance, resolution, and light source (e.g., laser or LED).

2. Optical Design
   We simulate and optimize performance using Zemax OpticStudio, focusing on MTF, color correction, and distortion.

3. Mechanical & Thermal Integration
   Full opto-mechanical design including housing, zoom/focus mechanisms, and thermal considerations.

4. Rapid Prototyping
   Using diamond turning, ultra-precision grinding, and coating equipment in-house for fast turnaround.

5. Metrology & Validation
   Each lens is inspected for resolution, focal accuracy, and environmental robustness using TriOptics MTF benches, interferometers, and alignment equipment.

🧩 Manufacturing Technologies

To ensure the highest optical performance and manufacturing precision, Yighen employs:

• Diamond turning for aspheres and freeform projection lenses

• Ultra-precision polishing for low-RMS optical surfaces

• Multi-layer broadband AR coatings (customizable spectrum 400–1100 nm)

• Injection molding for plastic optics (for mass production of pico projection lenses)

• Lens barrel alignment and active centering

🧰 Custom vs Pre-Engineered Options

We offer:

• Custom projection optics – Tailored for your system, resolution, and space constraints

• Pre-engineered designs – Optimized base designs ready for minor tweaks (save time & cost)
