Zorsika also offers alternative lenses for many well - known projector brands, and the WK051 lens is a prime example for the Epson CB - L690U.
Zorsika WK051 Lens: Key Features and Specifications
The Zorsika WK051 lens, with the product code D67 - 047, is a remarkable piece of optical engineering. It has an Ff of 2.0 /6.9mm and can resolve images up to 4K quality. The lens is designed with a 1P + 16G structure. It can project an image up to 500 inches and has an optimal performance range of 300 inches. The MTF (Modulation Transfer Function) at 70lp/mm center is ≥ 65%, indicating excellent image sharpness and clarity.
The lens is compatible with the L530 platform and has a compact size of φ112mm * 169mm. It is designed for a 0.67 - inch panel and supports both 4K and 2K resolutions. The most striking feature of the WK051 lens is its 0.46:1 throw ratio, which is significantly different from the native throw ratio of the Epson CB - L690U. This low throw ratio allows for a much shorter projection distance, enabling users to project large images in small spaces.
In terms of lens shift, the WK051 offers an impressive 85.2% vertical displacement and 39.6% horizontal displacement. This provides users with great flexibility in positioning the projector, eliminating the need for perfect alignment with the projection surface. Additionally, the lens has an optical efficiency of 86.5% compared to the standard lens, ensuring that a large portion of the light from the projector is effectively utilized for image projection, resulting in brighter and more vivid images.
Application Scenarios and Advantages
Small - Space Projection
In scenarios where space is limited, such as small meeting rooms or home theaters with restricted wall space, the 0.46:1 throw ratio of the Zorsika WK051 lens is a game - changer. With the Epson CB - L690U equipped with this lens, users can project large, high - quality images even when the projector is placed very close to the screen. This opens up new possibilities for creating immersive visual experiences in spaces that were previously considered unsuitable for large - screen projection.
Flexible Installation
The significant lens shift capabilities of the WK051 lens, combined with the short throw ratio, offer unparalleled flexibility in projector installation. Users can mount the projector at various angles and positions, and still achieve a perfectly aligned and distortion - free image on the screen. This is especially useful in irregularly shaped rooms or when the projector needs to be installed in a non - traditional location.
Cost - Effective Upgrade
For users who already own an Epson CB - L690U projector, the Zorsika WK051 lens provides a cost - effective way to upgrade the projection capabilities. Instead of investing in a new projector with a short - throw feature, users can simply purchase this lens and unlock new possibilities. This not only saves money but also allows users to continue using their familiar projector while enjoying improved performance.
High - Quality Image Output
Despite its short throw ratio and flexible installation options, the Zorsika WK051 lens does not compromise on image quality. With its support for 4K resolution, high color reproduction, and low light loss, it ensures that the projected images are sharp, vibrant, and true to the original content. Whether it's for business presentations, educational materials, or entertainment purposes, the lens delivers an exceptional visual experience.
In conclusion, the Zorsika WK051 0.46:1 projector lens is an excellent addition to the Epson CB - L690U projector. Its unique features, such as the short throw ratio, large lens shift, and high - quality image output, make it a valuable solution for a wide range of projection scenarios. Zorsika's commitment to innovation and quality is evident in this lens, and it continues to solidify its position as a leading supplier of projector accessories in the market.
