FA109 Projector Lens for HiteVision HT-D203UA and 1 Other Model

FA109 is a medium-to-long-throw lens for engineering projectors (Honghe). It is compatible with 1 model from 1 model series. This article presents the lens specifications, installation distance, model compatibility list, and replacement considerations in one place.

1. Lens Specifications

2. Installation Distance

Throw-ratio specifications for this model are not currently available. For installation distance, refer to the nameplate on the actual product and the user manual, or contact us for calculations based on on-site dimensions.

3. Compatible Projector Models (1 Model, Honghe)

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

The zoom ratio shown is the zoom factor of the model’s original standard lens (upper limit of the original throw-ratio range ÷ lower limit), not the zoom range of the lens featured in this article.

OEM Replacement Lens Models

Within this group, 1 model supports replacement with an OEM lens. The corresponding throw ratios for each lens model are listed below for comparison with OEM configurations.

Common Characteristics of These Models

For the 1 model covered here, the original standard lens typically has a throw ratio in the 1.5-2.0:1 range. The lens featured in this article effectively adjusts the focal range, allowing different image sizes at the same projection distance—this is the direct reason for replacing the lens. It also retains full lens-shift capability, so the image can still be aligned after adjusting the focal range.

4. Three Checks Before Replacement

• Check the panel dimensions. The panel specifications for this model are not currently available. Please send us a photo of the nameplate on the unit for verification.
• Check the interface and locking mechanism. Platforms of the same generation generally offer good interface compatibility, but the positions of the locking clips vary by generation. If the image appears skewed or the edges are not sharp after installation, the issue is most often that the lock has not engaged fully, rather than a problem with the lens itself.
• A fixed-focus lens provides no zoom adjustment. Image size can only be changed by moving the projector, so the site dimensions must be measured accurately, with an additional 10–20 cm allowed at the endpoints.

To determine whether a model outside the list is compatible, the safest approach is to send us photos of the unit’s nameplate and original lens for verification. Platforms of the same generation often share the same interfaces, but the risk of placing an order based solely on a similar model designation is not worth taking.
