Zorsika WE213 Projector Lens 0.52–0.64:1 for 15 Vivitek Models

WE213 is a short-throw lens for 0.64-inch panels (InFocus), with a 0.52–0.64:1 throw ratio and lens shift. It is compatible with 15 projector models spanning one series. This guide brings together the lens specifications, installation distances, model compatibility list, and key replacement considerations.

1. Lens Specifications

Lens shift is the key distinguishing feature of this lens. With a shift range of ±18% horizontally and ±13% vertically, the projector can be installed off the screen centerline and the image shifted back into position without keystone correction. Keystone correction comes at a cost—every adjustment step sacrifices some effective pixels and blurs text edges. In installation projects, use lens shift instead of keystone correction whenever possible; image quality is the non-negotiable priority.

2. Calculating Installation Distance from Throw Ratio

A throw ratio is the ratio of the installation distance to the image width. This zoom lens (0.52–0.64:1) covers a range of installation distances for each image size, and any position within that range can be brought into focus during installation.

These figures represent the clear distance from the front of the lens to the screen and do not include space required for cooling and cabling at the rear of the projector. They are calculated for a 16:10 image; actual installation should be based on site measurements and the manual.

Image quality varies between the two ends of the zoom range: at the short-throw end, the image is brighter and the edges are slightly softer; at the long-throw end, the edges are sharper and brightness is slightly lower. When the venue allows, the middle of the range is recommended. After installation, find the sharpest position using the focus ring, then fine-tune the lens shift—adjusting both variables at the same time makes it difficult to dial in.

3. Compatible Models (15 Models, InFocus)

The table below is ordered from newest to oldest by model release date and includes the resolution, brightness, and factory-lens zoom ratio of each model, making it easy to identify the right option for project requirements.

The zoom ratio is the zoom factor of the model’s factory-standard lens (the upper limit of the factory throw-ratio range ÷ the lower limit), not the zoom range of the lens itself.

Common Characteristics of These Models

The factory-standard lenses for these 15 models generally have throw ratios within 1.16-1.9. The 0.52–0.64:1 ratio of the model in this article effectively changes the focal-length range, allowing different image sizes from the same projection distance—this is the direct reason for replacing the lens. Full lens-shift capability is retained, so the image can still be properly aligned after the focal range is changed.

4. Three Checks Before Replacing the Lens

• Confirm that the panel size and resolution match. This model is designed for 0.64-inch panels. Projectors with a different panel size or resolution may produce different projection results, so the safest approach is to check the projector nameplate before installation.
• Check the interface and locking mechanism. Interfaces are generally highly compatible within the same platform generation, but the position of the locking latch differs between generations. If the image is skewed or the edges are soft after installation, the most likely cause is that the lock is not fully engaged, rather than a problem with the lens itself.
• Account for the lens-shift range during installation. The lens-shift range provides some installation flexibility, but edge image quality declines when the shift is pushed to its limit. In actual use, keep the shift within 70% of the rated value.

For models not included in the list, it is safest to send us the projector nameplate and a photo of the original lens for verification—projectors on the same platform generation often share an interface, but the risk of placing an order based on a similar model number is not worth taking.
