WJ162 Projector Lens 0.62–0.8:1 for 1 Wincent Model, Including C-4K1200

WJ162 is a short-throw lens for the 0.65/0.66/0.67 panel group (Winmate), with a throw ratio of 0.62–0.8:1 and lens shift. It fits 1 model and 1 model series. This article lists the lens specifications, installation distances, model compatibility list, and replacement key points all in one place.

I. Lens Specifications

The shift capability is the key differentiator of this lens. A shift range of ±53% horizontal and ±23% vertical means the projector can be installed off the screen's central axis, with lens shift pulling the image back into alignment—no keystone correction needed. Keystone correction comes at a cost: every step of correction loses some actual pixels, and text edges become blurry. In professional installation, whenever shift can solve the problem, never rely on keystone correction; this is the baseline for image quality.

II. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This lens is zoomable (0.62–0.8:1), so a given image size corresponds to a range of distances; any position within that range can be brought into focus during installation.

The above figures are the clear distance from the front of the lens to the screen, excluding space for rear cooling and cabling on the projector body. Calculated for a 16:10 image; actual values depend on on-site measurement and the manual.

Image quality differs at the two ends of the zoom range: closer to the wide end, the image is brighter and the edges slightly loose; closer to the tele end, the edges are sharper and brightness drops slightly. When the site allows, the middle of the range is recommended. After installation, first find the sharpest position on the focus ring, then fine-tune the shift—adjusting both variables at once makes it hard to dial in.

III. Compatible Models (1 unit, Winmate)

The table below is sorted by model production date, from newest to oldest, and lists the resolution, brightness, and factory lens zoom ratio of each model for quick reference against project requirements.

Common Traits of This Model

The factory-standard lens throw ratio for this 1 model is typically listed as Depends on the lens. The throw ratio of 0.62–0.8:1 for the model in this article effectively adjusts the focal range, allowing different image sizes at the same projection distance—which is precisely the direct reason for changing the lens; at the same time, full shift capability is retained, so the image can still be aligned after the focal range is adjusted.

IV. Three Things to Confirm Before Replacement

• Match the panel and resolution. This model is designed for 0.67 inch panels. Projectors with a different panel size or a different resolution will show some differences in projection performance; checking against the nameplate on the projector body before installation is the safest approach.
• Mounting interface and locking mechanism. Interfaces on the same-generation platform are generally highly compatible, but the position of the locking catch differs between generations. If the image appears skewed or the edges are not sharp after mounting, this is most often due to the lock not being fully engaged, rather than an issue with the lens itself.
• Factor shift headroom into the installation. The shift range leaves some margin for installation, but image quality at the edges degrades when the shift is pushed to its limit; it is recommended to keep actual use within 70% of the nominal value.

For models not on the list, the safest course is to send us the nameplate and a photo of the original lens for verification—interfaces are often shared across the same generation of platform, but placing an order based on a similar-looking model is not worth the risk.
