NEC NP16FL Fixed Short-Throw Lens Guide: 11 Compatible Models

NEC OEM Lens NP16FL Fixed is a short-throw (Short Throw) optical accessory for NEC professional projectors, with a throw ratio of 0.76:1. The factory compatibility list covers 11 models. Before installation, simply verify the projector model and panel size against the list—no adapter rings are needed. The value of an OEM lens lies not in extra specification rows, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series. Once installed, image-circle coverage, edge illumination, and focusing travel all meet the design values, eliminating the need to compensate for image quality with keystone correction.

1. Lens Specifications

The above specifications are subject to the factory specifications. Mechanical dimensions, flange distance, and mount type are not included in the specifications table. Please verify them with us using the projector model. Ordering solely on the basis of a similar model carries the risk of an incompatible fit.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens has a fixed focal length (0.76:1), so the installation distance varies linearly with image size and offers no adjustment margin. Accurate measurements are essential before installation.

These figures represent the clear distance from the front of the lens to the screen and do not allow for ventilation or cabling space behind the projector housing. They are calculated for a 16:10 image; the actual distance depends on on-site measurements and the factory manual.

3. Compatible Projector Models (11 Models)

The following table is based on the factory compatibility list. Brightness and resolution values are sourced from the model database; unavailable values are shown as “—” and are not estimated.

To confirm whether a model outside this list is compatible, send us a photo of the projector nameplate and the existing lens. Platforms from the same generation often share the same mount, but ordering based on a similar model is not worth the risk.

Throw Ratios by Model Series

The nominal throw ratio varies by projector series when the same NP16FL Fixed lens is installed. Select the value that corresponds to the actual projector series.

4. Three Checks Before Installation

• Confirm the projector panel and resolution.OEM lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the panel, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first.This lens has a nominal throw ratio of 0.76:1. Use the table in Section 2 to calculate the distance for your installation site. A fixed-focal-length lens offers no adjustment margin; even with a zoom lens, allow 10–20 cm at both ends of the range.
• Verify the mount and locking mechanism.The OEM lens is calibrated to the mount of the corresponding projector series. You must hear it lock securely into place after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a defect in the lens.

If you are unsure, send us one photo each of the projector nameplate and the existing lens nameplate. Physical verification is the most reliable approach.
