Works with the room lights on
Less than 100W electrical power consumption
Uniform illumination across the field of view

The tiled images below show many of the features of the system. The widefield image shows the captures H&E stained images. These can be
overlayed over the 2 photon images. The 2 photon images are made of 7 x 5 tiles. Each image is 650 um x 650 um making the whole tiled image
4.5 mm x 3.2 mm. The PXYL system has no image distortion, so the images can be butt coupled together with no overlap. Illumination is
flat to the edges of each image, so no processing is required. This unique feature makes tiling of large areas super easy.

Applications
Spheroids, Organoids and Gastuloids
Whether you want to image live or fixed or cleared samples, we can help.
Mount your samples in well plates, petri-dishes or chambered slides.
Control the temperature and CO2 levels to maintain you cells over hours and days.
Take time lapse images to monitor growth and changes.
Take Z stacks or single sections, tile large areas with a couple of clicks.
Use the 4mm working distance to reach transwells with ease.
Thick Sections
The deep sectioning afforded by the longer wavelength 2-photon excitation
combined with the large working distance allows you to see through thick sections.
Like this example of a mouse lung.
The sample is 200 microns thick.
This images is taken 100um down. Field of View 300 x 300um.
PXYL system can image though the sample in 1 micron steps.
Cells
While cells are thin and can be imaged using confocal microscopes,
they are not always in a single layer and they are not always easy to reach.
PXYL's 4mm working distance allows you to search through the deepest wells.
Multi-photon also offers advantages like reduced photo-bleaching and photo-toxicity.
This means that cells can be imaged for hours without observable damage.
Ideal for longer time studies.
Microfluidics
Difficult to reach samples are our speciality.
Microfludic structures mounted on slide-like platforms can be hard to reach
and difficult to navigate. The 20mm FOV brightfield overview, the 1.5mm scan FOV
the 4mm working depth and long wavelength 2-photon penetration make the task easier.
PXYL's Journey
PXYL's engineers worked on some of the first multi-photon systems back in the 1990s. At the time the technique showed
great promise for deep imaging because it used longer wavelength light. Longer wavelengths are scattered less in dense
media, so they can penetrate further and suffer less optical abberations. At the time researcher were working in 2D cell cultures,
so as a technique it was largely forgotten.
Fast-forward to today and researchers are again looking for deeper and deeper imaging due to the
rise of 3D cell cultures. Multi-photon is a great choice, except for the cost, complexity, size and unkeep, Right?
Wrong! This is where PXYL comes in. We have taken our cumulated knowledge of multi-photon and
completely redesigned the system. We started with the laser and then the microscope and finally combined the two into one small box.
It really is a Black Box!
Most end users want a system that works reliably with minimal input and maximum output. That's what PXYL delivers.
PXYL's approach of redesigning the microscope and laser together has led to a much simpler
microscope with a much higher optical transmission. Typical existing microscope systems
have an optical transmission of 10-15%, while the PXYL system exhibits a transmission
of over 90%. In addition, the simpler microscope design reduces spatial and temporal
aberrations, thus delivering a high-quality optical pulse to the sample. Furthermore,
PXYL believes that table-top multi-photon microscopy with multiple fixed-wavelength
laser sources rather than one tuneable one will deliver significantly higher utility
for the end users.
