Appotronics AL-EL062FR Fixed Short-Throw Lens: 8 Compatible Models

Appotronics Original Lens AL-EL062FR Fixed is a genuine optical accessory for Appotronics engineering projectors, featuring a short throw (Short Throw) and a 0.62:1 throw ratio. The factory compatibility list covers 8 models: simply verify the projector model and panel size before installation—no adapter ring is needed. The value of an original lens lies not in the extra figures on a specification sheet, but in the fact that it is factory-calibrated for the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all meet their design values, eliminating the need to use keystone correction to compensate for image quality.

I. Lens Specifications

Brand	Appotronics (Appotronics)
Lens Model	AL-EL062FR Fixed
Throw Ratio	0.62:1
Product Type	Short Throw
Compatible Models	8 models
Warranty	12 months; damage not attributable to user handling is covered through after-sales service, based on the date shown on the shipping invoice

These specifications are subject to the factory specifications. For mechanical dimensions, flange distance, and mount type not listed in the specification table, please provide your projector model so we can verify compatibility with you. Ordering solely because the model is similar carries the risk that the lens will not fit.

II. Converting Throw Ratio to Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This original lens has a fixed focus (0.62:1), so the installation distance varies linearly with image size and offers no adjustment margin. It must be measured accurately before installation.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 1.33 m
120 inches	2.58 m	Approx. 1.60 m
150 inches	3.22 m	Approx. 2.00 m
200 inches	4.30 m	Approx. 2.67 m

The distances above are the clear distances from the front surface of the lens to the screen and do not include space behind the projector for ventilation and cable connections. These calculations are based on a 16:10 image; actual site measurements and the factory manual take precedence.

III. Compatible Models (8 Models)

The following table is taken from the factory compatibility list. Brightness and resolution are populated from the model database; unavailable data is shown as "—", with no assumptions made.

Model	Brightness	Resolution
AL-FU750A	—	—
AL-FU755A	—	—
AL-FU820A	—	—
AL-FU825A	—	—
AL-FU905A	—	—
AL-SU10KA	—	—
AL-SU13KA	—	—
AL-SU15KA	—	—

To confirm whether a model not listed here is compatible, please send us photographs of the projector nameplate and the existing lens for verification. Projector platforms from the same generation often share the same mount, but ordering solely because the models appear similar is not worth the risk.

Throw Ratio by Projector Series

The nominal throw ratio varies by projector series when the same AL-EL062FR Fixed lens is installed on the series listed below. Use the value for the actual projector series when selecting a lens.

Projector Series	Throw Ratio
—	0.62:1

IV. Three Checks Before Replacement

• Confirm the projector chip and resolution. The original lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full panel, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first. Use the lens's nominal throw ratio of 0.62:1 and the dimensions of your installation site, as shown in the table in Section II. A fixed-focus lens offers no adjustment margin, and even a zoom lens should allow an additional 10–20 cm at both ends.
• Verify the mount and locking mechanism. The original lens is calibrated for the mount of that projector series. You must hear it lock into place after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a problem with the lens itself.

If you are unsure, photograph the projector nameplate and the existing lens nameplate and send them to us. Verification against the actual equipment is the most reliable approach.
