WK223 Projector Lens 0.46:1

WK223 is a short-throw lens for the 0.65/0.66/0.67 projector panel range (engineering projectors), with a throw ratio of 0.46:1. It is compatible with 0 projector models across 0 model series. This guide presents the lens specifications, installation distance, model compatibility list, and replacement considerations all in one place.

1. Lens Specifications

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This lens has a fixed focal length (0.46:1), so the installation distance varies linearly with the image size, with no adjustment margin. Accurate measurements are essential before installation.

These figures represent the clear distance from the front surface of the lens to the screen and do not include space for rear chassis cooling or cable connections. They are calculated for a 16:10 image; actual values must be verified by on-site measurement and the manual.

4. Three Checks Before Replacement

• Make sure the panel and resolution match. This model supports panels measuring 0.67 inches. Projectors with a different panel size or resolution may show differences in projection performance, so it is safest to check the chassis nameplate before installation.
• Check the interfaces and locking mechanism. Interfaces are generally compatible across platforms of the same generation, but the locking latch positions vary by generation. If the image appears skewed or the edges are not sharp after installation, the locking mechanism is usually not fully engaged, rather than there being a problem with the lens itself.
• Fixed focal length leaves no zoom adjustment. Image size can only be changed by moving the projector, so the venue dimensions must be measured accurately beforehand. Leave an additional 10–20 cm at the endpoints.

For models not listed, it is safest to send us a photo of the chassis nameplate and the original lens so we can verify compatibility. Platforms of the same generation often share interfaces, but ordering based only on a similar model number carries unnecessary risk.
