Highly desirable High End Laser Projectors

Multi-Laser Module Structure
The multi-module structure laser light source supports continuous 24/7 operation. The laser beam is produced by multiple laser diodes, increasing reliability.

High Brightness
The RICOH PJ WUL6670, PJ WUL6680 and PJ WUL6690 models continuously and stably deliver brightness levels of 7,200lm, 8,500lm, and 9,600lm respectively. Clear, sharp images can be obtained even in bright environments, making these projectors suitable for applications in various fields such as large auditoriums, conference rooms, hotels, and large-scale exhibitions, among others.

High Image Quality and Wide Colour Gamut
Using a WUXGA chip to project widescreen, high-definition images, these DLP projectors combine RICOH's unique NCE natural colour gain technology, RGB advanced adjustment and GAMMA type selection to efficiently cover over 97% of the Rec.709 colour gamut range, delivering natural and realistic colours.

20,000-Hour Long Life
The laser light source has a long life of 20,000 hours, which is 6-7 times the life of a typical projector bulb source.

4K Signal Compatible Display
3840 x 2160HZ compatible, which means this device can directly play 4K resolution format, audio and video content.

Multiple Remote Image Correction Functions
Supports ± 30° horizontal and vertical keystone, four corners, six points and grid image correction functions. The remote control enables easy geometric correction for projection onto surfaces such as spheres and curved screens.

Remote, Electric Focus / Zoom / Lens shift
The wide ±25% horizontal and ±55% vertical image adjustment ranges of the electric lens shift, greatly increase freedom of installation position. This family of projectors supports remotely controlled motorised focus, high magnification zoom and image adjustment functions, without needing to move the projector.

IP5X Dust-proof Design
Dust is a key factor affecting the lifespan of a projector. The key optical components of the PJ WUL6670, PJ WUL6680 and PJ WUL6690 models use a specially designed, sealed optical structure, achieving an IP5X dust-proofing level to prevent dust from damaging the unit.

Edge Blending Function
Avoid additional edge-blending software costs thanks to the built-in edge-blending function. Multiple large images can be combined to produce a single, seamless, extremely large image. Excess brightness in overlapping parts can be eliminated by adjustment of the fusion band.

HDBaseT
HDBaseT technology is a multi-signal transmission system that uses a single fibre-optic cable. High-definition video and document data can be transmitted uncompressed through LAN cable, up to a maximum transmission distance of 100m by using HDBaseT technology.

360-Degree Installation and Portrait Orientation Support
These models can be installed to project through 360 degrees, making them highly flexible, reducing installation limitations and greatly expanding the application range to include scenarios such as projection onto ceilings and floors, along with portrait orientation.

Supports DICOM SIM medical mode
Equipped with DICOM SIM (Digital Imaging and Communications in Medicine Simulation), these models are suitable for projecting monochromatic medical images, such as X-ray films, MRI, and tomography images. Details of medical images can be presented to a wider audience in a large, high-definition format, ideal for medical education environments.

Picture in Picture and Picture By Picture
It is possible for a single projector to simultaneously project the content of two input sources on one screen, enabling the projection of multiple images, whether in PIP or PBP format.

Customisable ID Remote Control
Up to 99 projectors can be assigned a separate ID and individually controlled, one at a time.

Network Management, Remote Projector Monitoring Support
These projectors support various network protocols such as "Extron", "PJ Link", "AMX", "Telnet", and "Webserver" via an inbuilt application. This manages the status and operation of multiple network projectors such as power ON / OFF, and input source switching.

Mercury-free
The solid-state semiconductor laser light source used in these models contains no harmful mercury elements – unlike many bulb projectors, which use high voltage mercury lamps.
High brightness short throw laser projector
At 6000 lumens, with 4K and HDR compatibility, the ZU607TST features a dust-resistant IP6X certified optical engine for 24/7 operational capabilities and low maintenance. The ZU607TST short throw projector features extremely long-life laser technology, manual horizontal and vertical lens shift and built-in 15W speakers.

Suitable for a wide variety of applications, this projector is perfect for anywhere that requires a clean bright image including large venues, classrooms, lecture theatres, museums, houses of worship, digital signage or immersive installations.

The added control flexibility of HDBaseT 3.0 and LAN make this projector an affordable set-and-forget solution.

Lights on viewing
This versatile projector combines high brightness and vivid colours for vibrant, true-to-life visuals in any environment. Make a lasting impression with bigger and bolder presentations any time of day.

HDR and HLG compatible
Capable of receiving and displaying both HDR10 and Hybrid Log Gamma (HLG) HDR content. This Optoma projector allows you to see far more detail and texture. Objects look more solid and lifelike and the extra detail creates a greater sense of depth.

Superior contrast
Add more depth to your image with a high contrast projector. Compared to competing technology, Optoma DLP projectors provide you with brighter whites and ultra-rich blacks, images come alive and text appears crisp and clear - ideal for business and education applications.

Short Throw
With a short throw lens, you can project an impressive 100” image from just over a metre away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease.

DuraCore
Industry leading lifetime is achieved using Optoma’s DuraCore technology. Implementing advanced laser diode cooling techniques and an innovative dust resistant design.

Auto keystone
Auto keystone automatically adjusts the trapezoid effect to create a perfectly aligned image when a projector is off-axis, or the desired projection surface is not perfectly flat.

Four corner correction
Adjust the keystone in both the vertical and horizontal plane. You can individually warp each corner of the image to create a perfectly square image. Ideal for image stacking, uneven walls or where projector placement is awkward and needs to be installed at an angle.

Game mode
Game mode optimises your projector for maximum contrast and vivid colours to capture every detail - leaving you time to focus on winning.

HDBaseT™
Uncompromising, uncompressed Full HD video, audio, network and control commands all delivered on a single CAT- type cable capable up to 100 meters/328 feet without signal loss makes installation hassle-free. HDBaseT™ simplifies cabling requirements and reduces installation complexity saving both time and reducing costs.
