UV Solutions

FlexLight LC4500-UV

The FlexLight™ LC4500UV projector is a production-ready, full-featured implementation of the Texas Instruments DLP4500 chipset.  This chipset includes the powerful DLPC350 processor and 0.45″ WXGA DMD with more than 1million pixels.

The LC4500UV  provides a  high resolution projector for your 3D measurement and display applications using the Texas Instruments DLP4500 chipset. An on-axis projection lens with a 1.2 throw-ratio provides excellent uniformity; and short focus capability enables a wide range of applications, starting with 3D printing.

FlexLight 4K-HLD-405 EVM

The FlexLight 4K-HLD-405 is a modification of our standard 4K evaluation projector.  Instead of displaying high resolution images using red, green, and blue LEDs, we have replaced the Blue LED with a UV LED wavelength centered on 405 nm.

Keynote Photonics modified a standard RGB high-resolution projector to provide advanced UV capability

We have also modified the projector’s firmware to map all of the input data to the “blue” channel.  By doing so, we dedicate the entire exposure time to projecting UV data.  This greatly increases the energy available to expose your photo-sensitive material.  This opens new opportunities in areas such as 3D printing and photo-lithography.

Just like our 4K RGB display projector, this UV version comes with direct support to interact with the TI DLP 4K chipset using TI’s DLP Composer(tm) software.  With a standard USB connection and Keynote’s custom “.projector” file, you can easily control the display settings to match your own requirements.

If you need further customization of the projector, we offer firmware design services for the projector’s DLP660TE chipset.  Please describe your request in the contact form here

Although this is an evaluation, please contact us when you are ready to transition to a customized production solution.

LUXBEAM RAPID

Luxbeam RapidFor the highest pixel resolution in high-power UV-capability projectors, Keynote offers the Visitech LUXBEAM® RAPID SYSTEM (LRS)*.  The LRS projectors are DLP® based stereo lithography sub-systems designed for additive manufacturing of high resolution parts.

The LRS can be configured in 2 ways:

1) for stand still projection, as typically used in rapid prototyping / manufacturing.

2) for combining the LRS with a synchronised and controlled motion system for scrolling over a larger area and keep the resolution or even increase it.

The LRS thoroughly supports large scale manufacturing of many equal parts at high speed. The LRS uses the advantage of a moving photo head to create a large build area and enables smart functions like Subpixelation (SPX) for resolution enhancement, and Pixel Power Control (PPC) ensuring equal amount of energy to each pixel in the resin.

The system includes an UV LED light source which in combination with the robust and reliable DLP® technology provides a system with long life time and low maintenance cost. The LRS is configurable and is available in single or multi head configuration to fit the needs for throughput and build area in the machine. The already proven and reliable LRS is a plug and play system/module that will enable customers to design, build and brand a Rapid Manufacturing machine with a very short time to market  and with low technical risk.

The LRS will provide a system capable of 25µm in XYZ resolution in combination with 10 – 20 cm width of build area and a customer defined length in the motion direction, – typical 1 meter. Other configurations with higher or lower resolution can be configured via dedicated lens design.

Our reference Lithography machine is available for demonstration and test manufacturing of samples for evaluation of single layer 3D perfomance and throughput.

LUXBEAM LRS

The LUXBEAM® LRS product line provides robust light engine configurations for industrial implementations, comprising various high resolution DMD micro displays and using the same highly efficient optical core as the LE4960H platform.

Based on Visitech’s advanced LB4600 formatter board configuration and spectrally optimized light engines (either for visible or UV range), static as well as dynamic industrial implementations (step-and-flash or scrolling on the fly) are supported.

Visitech’s proprietary SPX subpixelation and PPC pixel power control technology can be applied specifically in scrolling systems.

Application areas: primarily high-end industrial implementations, but also high-end scientific applications with demands for high optical power output (UV or VIS), high resolution, superior frame rates, single pixel control such as
• 3D Print/Additive Manufacturing
• CtP and lithographic printing
• Inline inspection
• Life Science and biotechnology
• Structured illumination
including advanced implementations with scrolling, subpixelation (SPX) and pixel power control (PPC).

LENS OPTIONS

The reference projection lenses are mostly dedicated lens designs optimized for transmission and image performance in Deep-Blue and N-UV applications. A wide range with different lens magnification options is offered.

Customization options are available for other magnifications. The magnification is the scaling factor from the native DMD pixel pitch into the image plane, while the power factor indicates the scaling factor for light engine optical power output to image plane, given by the projection lens numerical aperture.
