μLaser is a high value direct laser lithography writer, oriented to universities and research facilities looking to expand their capabilities.
It writes on a photosensitive resist coated surface with a 405nm laser at submicron pixel resolution on big areas. You can write anything from photomasks to research prototypes for basic or applied science, the integrated camera can be used to align the writing with existing features.
We have optimized it for ease of use and simple maintenance, maximizing the use of off-the-shelf parts without sacrificing writing quality or capabilities.
Direct laser lithography greatly reduces costs and execution times in areas such as microfluidics, microelectronics, micromechanics and material science research, by eliminating the dependence of external suppliers for the production of photomasks.
µLaser can get to sub-micron resolution and produce five micron features.
You can make full size photomasks for production or in-house usage.
µLaser is controlled from an user friendly software on a laptop. It can import GDSII files and PNG images
The last lens is an industry standard microscope objective. Replace it to change the spot size!.
We include four microscope objectives.
Using the confocal yellow illumination and camera you can use the µLaser as a microscope
We have managed to keep the prices low allowing you to have a better lab on a tight budget.
microLaser size is only 510x360x455mm and weighs 16kg, making it ideal for use inside of a fume hood or a glove box. Reducing requirements and improving the cleanliness of microfabrication processes.
μLaser is delivered with its control software on a PC. It allows you to import the designs to be written from cells of GDSII files or directly from PNG images.
Everything is done from a user friendly graphical interface that allows you preview the design to write before executing it.
Multiple designs can be combined in a single process, in addition to applying transformations such as rotations, reflections, inversions or scale adjustments to each design.
After defining the design, the included stage control modules and the confocal microscope are used.
With them you set the origin position of the process on the substrate and the focal plane on the photosensitive surface.
Next the process is executed and the design is written on the surface.
Our mask aligner, the microAligner, allows for easy fabrication of multilayer devices on a multitude of photoresists, with excellent exposure quality.
The microLaser system, as a complementary tool of the microAligner, offers the possibility for the fabrication of systems, sensors and devices with 3 to 5 µm of minimum feature size. Maskless lithography offers great speed and versatility for the fabrication of new devices and prototyping.
These possibilities make the microLaser and microAligner package the ultimate solution for the fast fabrication and development of multilayered device applications including biomedical, microfluidics and microelectronic devices.
