This article will delve into the application of Zorsika's LC020 projector lens on the Epson CB - L690E projector, highlighting the advantages and compatibility of this combination.
Epson CB - L690E: A Powerful Projection Solution
The Epson CB - L690E is a remarkable projector with a set of impressive specifications. It adopts the 3LCD display technology, which is well - known for delivering vivid and natural colors. The 0.67 - inch chip size and 4K (3840 x 2160) resolution ensure that every detail is presented with utmost clarity, whether it's for business presentations, educational content, or home entertainment.
With a brightness of 7100 lumens, the CB - L690E can project clear and bright images even in relatively well - lit environments. Its throw ratio ranges from 1.35 - 2.20:1, and the F - number is between 1.5 - 1.7. The lens has a focal length of 20.0mm - 31.8mm and a 1.6X zoom ratio, allowing for some flexibility in adjusting the image size. Additionally, it offers significant lens shift capabilities, with vertical shift ranging from - 20% to + 20% and horizontal shift from - 50% to + 50%. These features make it a versatile projector suitable for various installation scenarios.
Zorsika LC020: A High - Performance Alternative Lens
Zorsika's LC020 projector lens (product code: D67 - 300) is a high - quality alternative that can perfectly complement the Epson CB - L690E. It is designed with a focus on providing excellent optical performance and ease of use.
Optical Performance
The LC020 lens has a focal length range of 21.5 - 43.0 mm and an F - number range of 2.0 - 3.4. It supports 4K resolution, ensuring that it can fully utilize the high - resolution capabilities of the Epson CB - L690E. The lens is engineered to have extremely high color reproduction accuracy, which means that the projected images will have vibrant and true - to - life colors, just as expected from a high - end projection system. Moreover, it has extremely low light loss, allowing more of the projector's light output to reach the screen, resulting in brighter and more impactful images. The high contrast ratio further enhances the visual experience by providing deep blacks and bright whites, making the images more three - dimensional and engaging.
Throw Ratio and Compatibility
One of the key advantages of the Zorsika LC020 lens is its throw ratio of 1.5 - 3.0:1. This range makes it highly compatible with the Epson CB - L690E, which has a throw ratio of 1.35 - 2.20:1. The overlapping throw ratio range allows for a wide range of installation options. Whether the projector needs to be placed relatively close to the screen for a smaller room or further away for a larger venue, the LC020 lens can adapt to different distances and still project a clear and well - sized image.
Lens Shift Capabilities
The LC020 lens also offers impressive lens shift functions. It has a vertical shift of + 64% and - 44%, and a horizontal shift of + 34% and - 27%. These generous shift ranges provide great flexibility in adjusting the position of the projected image without having to physically move the projector. This is especially useful in situations where the projector cannot be installed in the ideal center position, such as in rooms with existing furniture or architectural constraints.
Installation Ease
Zorsika understands the importance of a simple and straightforward installation process. The LC020 lens is designed with a scientific structure that makes it easy to install on the Epson CB - L690E. Users do not need to be professional technicians to complete the installation.

Cost - Effectiveness and Value
In addition to its excellent performance, the Zorsika LC020 lens offers great cost - effectiveness. As a high - quality alternative to the original lens, it provides similar or even better performance at a more competitive price. This means that users can enjoy the benefits of a high - end projection system without having to pay a premium price. For businesses and educational institutions that need to equip multiple rooms with projectors, choosing Zorsika's LC020 lens can result in significant cost savings while still maintaining high - quality projection performance.
