LC01A Projector Lens 1.5–3:1 for 4 Models Including Zhongke MU10 and MU9

LC01A is a long-throw lens for 0.65/0.66/0.67 display panels (Zhongke and Honghe), with a 1.5–3:1 throw ratio and lens shift. It is compatible with 4 projector models from 2 model series. This guide consolidates the lens specifications, installation distances, model compatibility list, and replacement considerations.

1. Lens Specifications

Lens shift capability is the key differentiator of this lens. The horizontal +64 %, -44 % and vertical +34 %, -27 % shift ranges allow the projector to be installed off the screen’s central axis, with the image repositioned through lens shift rather than keystone correction. Keystone correction comes at a cost—each correction step sacrifices some effective pixels and can blur text edges. In professional installations, never use keystone correction when lens shift can resolve the issue; this is the minimum standard for image quality.

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 zoom range of 1.5–3:1, so each image size corresponds to a range of installation distances, and the lens can be focused anywhere within that range during installation.

These figures represent the clear distance from the front of the lens to the screen and do not include space behind the chassis for ventilation and cable connections. They are calculated for a 16:10 image format; actual site measurements and the manual take precedence.

Image quality differs at the two ends of the zoom range: images are brighter with slightly softer edges near the short-throw end, while edges are sharper with slightly lower brightness near the long-throw end. If the venue allows, target the middle of the range. After installation, first find the sharpest setting on the focus ring, then fine-tune the shift—adjusting both variables at once makes precise alignment difficult.

3. Compatible Models (4 Models, Zhongke and Honghe)

The table below is sorted by model production date, from newest to oldest, and lists each model’s resolution, brightness, and factory-lens zoom ratio to help you quickly identify the right option for your project requirements.

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

Common Features of These Models

The factory-standard lenses for the 4 models generally have throw ratios around 1.22-1.52：1. The 1.5–3:1 model featured here effectively changes the focal-length range, allowing the same projection distance to produce a different image size—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

• Make sure the panel and resolution match. This model is designed for 0.67 inches panels. Projection performance varies somewhat among machines with different panel sizes or resolutions, so checking the nameplate on the chassis before installation is the safest approach.
• Check the interface and locking mechanism. Mounting interfaces are generally well compatible within the same platform generation, but the positions of the locking tabs vary between generations. If the image is skewed or the edges are not sharp after installation, the lock is usually not fully engaged rather than the lens itself being faulty.
• Account for lens-shift margin during installation. The shift ranges provide some installation flexibility, but edge image quality declines when they are pushed to their limits. Actual use should therefore be kept within 70% of the rated values.

For models outside the list, the safest approach is to send us the chassis nameplate and photos of the original lens for verification. Platforms of the same generation often share interfaces, but placing an order solely because the model names appear similar is not worth the risk.
