The Epson CB-PU2220B is a powerhouse in the professional projection industry, renowned for its 3LCD display technology, 4K resolution (3840 x 2160), and 20,000-lumen brightness. Designed for large venues, theaters, and corporate environments, this projector delivers unparalleled image clarity and vibrant colors. However, its performance is only as good as the lens paired with it. While Epson offers a range of proprietary lenses like the ELPLX02S, ELPLU03S, and ELPLL08, third-party alternatives such as Zosica’s ZE3201 (ZW3201) provide a cost-effective, high-quality solution without compromising on performance. This article explores how the ZE3201 lens complements the CB-PU2220B, offering flexibility, efficiency, and exceptional value.
Understanding the Epson CB-PU2220B’s Lens Requirements
The CB-PU2220B’s versatility stems from its compatibility with multiple lenses, each tailored to specific throw distances and room configurations. Key factors to consider when selecting a lens include:
- Throw Ratio: Determines the distance needed to project a specific image size.
- Lens Shift: Enables vertical and horizontal adjustment of the projected image without moving the projector.
- Optical Quality: Affects color accuracy, contrast, and light transmission.
- Compatibility: Must align with the projector’s 1.0-inch chip and 4K resolution.
Epson’s native lenses, such as the ELPLW08 (wide-angle) and ELPLM15 (mid-throw), cater to diverse setups but often come at a premium. This is where Zosica’s ZE3201 emerges as a compelling alternative.

Key Benefits of the ZE3201
- Superior Optical Performance
- The all-glass lens construction minimizes chromatic aberration and light loss, ensuring vibrant colors and high contrast—critical for the CB-PU2220B’s 3LCD technology.
- An MTF of >60% @ 67lp/mm guarantees edge-to-edge sharpness, even in fine details.
- Cost Efficiency
- Priced competitively, the ZE3201 offers a lower total cost of ownership compared to Epson’s proprietary lenses, making it ideal for budget-conscious installations without sacrificing quality.
- Flexible Installation
- With a throw ratio of 0.72:1, the ZE3201 excels in short-throw scenarios, projecting large images (up to 500") from minimal distances. This is perfect for compact venues like conference rooms or classrooms.
- While lens shift data isn’t specified, Zosica’s ergonomic design simplifies mounting and alignment, reducing setup time.
- Durability and Warranty
- Zosica provides an extended warranty period, underscoring confidence in the lens’s build quality and longevity. This aligns with the CB-PU2220B’s use in demanding professional environments.
Compatibility and Integration with CB-PU2220B
The ZE3201’s compatibility with the PU2000 platform ensures seamless integration with the CB-PU2220B. Key considerations include:
- Resolution Scaling: While the ZE3201 is natively WUXGA, it supports 4K input from the CB-PU2220B, downscaling efficiently without perceptible loss of detail.
- Throw Ratio Synergy: The 0.72:1 ratio complements Epson’s mid-to-long-throw lenses, offering users more flexibility in room design. For instance, in a 10-foot-wide room, the ZE3201 can project a 150" image, whereas Epson’s ELPLM10 (1.8–2.8:1) would require a deeper space.
Why Choose Zosica Over OEM Lenses?
