Zorsika's WK051 lens (product code: D67-047) is an excellent alternative for the Epson CB-L690E. Let's take a closer look at its specifications and how they align with the requirements of the CB-L690E.
Optical Performance
The WK051 lens has a lens resolution of 4K, which matches the native resolution of the Epson CB-L690E. This ensures that the projected images maintain their sharpness and detail, without any loss of quality. The MTF (Modulation Transfer Function) value of 70lp/mm center≥65% indicates that the lens can effectively transmit high-frequency details, resulting in clear and well-defined images.
In terms of light efficiency, the WK051 lens achieves 86.5% compared to the standard lens. This means that it can effectively utilize the light output from the projector, minimizing light loss and ensuring bright and vivid images. The high color reproduction and low light loss characteristics of the WK051 lens are in line with Zorsika's commitment to providing high-quality optical solutions.
Throw Ratio and Projection Range
The Epson CB-L690E has a variable throw ratio, and the Zorsika WK051 lens with a throw ratio of 0.46:1 offers a different projection option. This lower throw ratio allows for shorter projection distances, making it ideal for small to medium-sized rooms where space is limited. The WK051 lens can project images up to 500 inches, with an optimal performance range of 300 inches. This wide projection range provides users with flexibility in choosing the appropriate screen size based on their specific needs.
Lens Shift and Installation Flexibility
Similar to the Epson CB-L690E's original lens, the Zorsika WK051 lens also offers significant lens shift capabilities. It has an upward and downward displacement of 85.2% and a leftward and rightward displacement of 39.6%. These extensive lens shift options allow for easy adjustment of the projected image's position without the need to physically move the projector. This is particularly useful during installation, as it provides greater flexibility in aligning the image with the screen, even in challenging room layouts.
