BenQ 5J.JAM37.011 Wide Fixed Short-Throw Lens Guide: Compatible with 9 Models

BenQ Genuine Lens 5J.JAM37.011 Wide Fixed is a genuine OEM optical accessory for BenQ business projectors. It is a short-throw lens (Short Throw) with a throw ratio of 0.76:1. The official compatibility list covers 9 projector models. Before installation, simply verify the projector model and panel size; there is no need to improvise with adapter rings. The value of a genuine lens lies not in the extra rows of specifications, but in its factory calibration to the optical path and lens mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all meet the design values, eliminating the need for keystone correction to compensate for image quality.

1. Lens Specifications

Brand	BenQ (BenQ)
Lens Model	5J.JAM37.011 Wide Fixed
Throw Ratio	0.76:1
Product Type	Short-throw lens (Short Throw)
Compatible Projector Models	9 projector models
Warranty	12 months; damage not caused by the user is eligible for after-sales service, subject to the date on the sales receipt

The above specifications are subject to the manufacturer's official specifications. Mechanical dimensions, flange distance, and mount type not listed in the specifications table should be verified with us based on the projector model, as ordering solely on the basis of a similar model carries the risk of incompatibility.

2. Converting Throw Ratio to Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This genuine lens is fixed-focus (0.76:1), so the installation distance changes 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. 1.63 m
120 inches	2.58 m	approx. 1.96 m
150 inches	3.22 m	approx. 2.45 m
200 inches	4.30 m	approx. 3.27 m

The distances above are clear distances from the front surface of the lens to the projection screen and do not include cooling clearance or cable-routing space at the rear of the projector. They are calculated for a 16:10 image; actual distances should be verified on site and are subject to the manufacturer's manual.

3. Compatible Projector Models (9 units)

The table below is taken from the manufacturer's official compatibility list. Brightness and resolution are populated from the model database; where the data is unavailable, “—” is shown rather than guessed.

Model	Brightness	Resolution
LU9715	8000 lumens	WUXGA,1920 x 1200
PU9530	6000 lumens	1920x1200
PU9730	7000 lumens	1920x1200
PW9500	5700 lumens	1280x800
PW9520	6000 lumens	1280x800
PW9620	6700 lumens	1280x800
PX9510	6500 lumens	1024x768
PX9600	6500 lumens	1024x768
PX9710	7000 lumens	1024x768

For compatibility with models not on the list, please send us photos of the projector nameplate and the existing lens for verification. Platforms from the same generation often share the same mount, but ordering based on a similar model designation carries risks that are not worth taking.

Throw Ratio by Projector Series

The rated throw ratio varies across projector series when the same 5J.JAM37.011 Wide Fixed is installed. Select the value according to the series of the actual projector.

Projector Series	Throw Ratio
—	0.76:1

4. Three Checks Before Replacement

• Confirm the projector chip and resolution. The genuine lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 0.76:1; use the table in Section 2 to calculate the distance for your installation space. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires 10–20 cm of clearance at both ends.
• Check the mount and locking mechanism. The genuine lens is calibrated to the mount of that projector series. After installation, you must hear the lock engage. A skewed image and soft edges are usually caused by the lens not being fully locked, rather than by a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one of the existing lens nameplate and send them to us. Verification against the actual hardware is the most reliable approach.
