1. Larger Clear Aperture, Shorter Total Lens Length

In the design of wide-angle, large-format projection lenses, we optimize the lens group structure and apply aspherical technology to achieve a larger clear aperture while further compressing total lens length. This balances compactness with high performance, freeing up more space for overall system design.

2. Class-Leading MTF at Center and Edge at the Same Field of View

At equivalent fields of view, comparable lenses on the market typically show low MTF performance at both center and edge, limiting image quality. Through systematic optical optimization, this lens significantly improves MTF at both center and edge, delivering high-resolution imaging across the entire frame — with image quality clearly superior to comparable market products.

3. Consistent Imaging from Near to Far Object Distances

Thanks to the overall gain in image quality, the lens also delivers improved imaging at both near and far object distances. It maintains stable, sharp image performance across different projection distances, adapting to a wider range of practical applications.

4. Ultra-Wide Field of View and Ultra-Low Distortion, Combined

Built on a retro-focus optical architecture, this design targets ultra-wide field of view and ultra-low distortion as its core breakthroughs. A large-aperture negative aspherical lens corrects distortion, while alternating positive and negative lenses provide compensation. An optimized stop position, combined with a front negative lens, effectively suppresses barrel distortion — preserving excellent imaging geometric precision even at extremely wide fields of view.

5. Image-Side Near-Telecentric Design for Precise Light Source Matching

The rear section adopts an aspherical design to achieve a near-telecentric image-side optical path, enabling precise control over chief ray angles at the image plane. The chief ray cone angle at each field of view is matched as closely as possible to the divergence angle of the illumination LEDs — perfectly matching the illumination source and improving light energy utilization efficiency and image uniformity.

6. Multi-Wavelength, Multi-Channel Versatility with Balanced Image Quality

Through matched design of glass materials with large relative partial dispersion offsets, combined with multiple cemented lens groups, residual chromatic aberration across different spectral bands is effectively corrected — achieving balanced image quality for multi-wavelength, multi-channel universal lenses. The projection lens supports dual-color-channel operating wavelengths respectively, meeting the needs of multi-scenario, multi-channel projection applications.
