RI Saturn 5™ Laser 1

Fixed and Directional Laser Systems

As the pioneer of moveable lasers for Assisted Reproductive Technology, the RI Saturn 5 Active™ laser is spearheading a revolution in hatching and biopsy techniques in laboratories all over the world.

The RI Saturn 5™ Biopsy Mode is helping you to significantly improve biopsying methods; potentially reducing procedure time, lowering the incidence of blastocyst collapse and eliminating the need to mechanically tear off cells.

Using Biopsy Mode, you can draw a straight or curved line along the sample, select the number and size of holes, then simply “fire”. The laser will ablate exactly along the chosen path, meaning you no longer need to move the holding pipette at all. It is that easy.


This product is available for sale in the U.S.A and selected countries in Europe and the rest of the world.

“We have been using the RI Saturn 5 Active™ laser system for assisted hatching, blastomere biopsy and blastocyst collapsing since November 2012. The moveable RI Saturn™ laser means I can ablate the zona exactly where I want to, without having to move the embryo, also the new biopsy mode allows me to accurately make holes in either straight or curved lines along the zona. The new laser system from RI makes the procedures quicker, easier and safer to perform than ever before. We love it!”

Using a RI Saturn 5 Active™ has clear advantages to the welfare of the embryo.

Blastomere Biopsy, Polar Body Biopsy, Blastocyst Collapsing (for vitrification)

The RI Saturn 5 Active™ directional laser allows the embryo to stay in the desired position and focus so that ablations can be made wherever required without additional manipulation. Our Biopsy Mode also allows safe multi-pulse drilling along a predetermined line.

Assisted Hatching

The directional laser means that accurate ablations can be made without the need to hold the embryo, making it very quick and accurate, with no additional consumable costs.

*The applicability of procedures is dependent on the regulations of the country into which the device is sold.

Blastocyst/Trophectoderm Biopsy

The RI Saturn 5 Active™ is unparalled in its ease of use.

The directional laser allows the user to make multiple ablations across the trophectoderm cells without needing to move the blastocyst.

This gives the user superb accuracy, safety and incredible speed.

For Assisted Hatching, Blastomere, Polar Body and Trophectoderm Biopsies – and other procedures, it is necessary to make a hole in the zona pellucida. Using a laser to do this is more precise, safer and quicker1,2 than other methods. You may save a great deal in disposables such as Acid Tyrodes and pipettes, and the laser’s use will potentially reduce the amount of time lab staff spend preparing for and performing procedures2. One other very important factor is that lasers have the potential to standardize laboratory procedures by reducing operator variability, which can be a big problem when, for example, using Acid Tyrodes for Assisted Hatching.

2Lloyd S, Doshi A, Harper J, (2013). A new method of biopsying trophectoderm (TE) cells using the latest Saturn 5™ Laser System, offers several potential ways to improve procedures.

What are the advantages of using the Saturn 5 laser? A. The Saturn 5 Active laser can be directed to the target location, eliminating the need to move the embryo, which can be difficult and time-consuming. It has a visible pilot laser to ensure the laser is aligned to the objective (so that “flaring” of the laser beam does not occur) and to check the position of the laser when required. It has a high power and ultra-short pulse time combination to make the most energy-efficient holes with minimal heat transfer. Saturn 5 laser systems use shorter pulse times than any competitor system. They also come with a sophisticated software package – RI Viewer™ – to record images and data for both lab and patient use.

The pilot laser ensures the laser is not going to flare or spread heat where it is not required. Microscopes also have a number of moving parts which could affect the position of the laser such as the nosepiece, camera and port selector. The only way to be certain of the laser’s position is to check it before firing. Using a pilot laser that travels down the same fibre-optic as the main laser guarantees the position and reduces the need for additional service visits. RI lasers are calibrated to within 1µm accuracy.

Misalignment between the pilot laser and the infrared laser is not possible using a Saturn laser as the two travel down the same fibre-optic cable. Other systems have to be separately aligned. Shape and focus quality of the Saturn laser can be checked. This is not possible with other systems.

Research shows that the most efficient way to deliver laser energy is to use pulse length to control the hole size1. Doing this ensures the lowest amount of heat reaches the embryo, thereby lowering possible risk of thermal damage. Other laser systems do not allow the user to vary the power in clinical use, only in a non-clinical evaluation mode.

Our lasers are Class 1 (the safest level), as defined by IEC 60825 international laser safety standards, so no special safety precautions are required. We also fit an infrared filter to prevent any laser energy reaching the operator as an extra safety measure.

We have worked with embryologists to assess the damage to embryos at different pulse lengths and at varying distances from critical cells. Based on the results of the study3 we developed a visual “Exclusion Zone™” around the laser target which is a measuring tool that informs the user where the heat is applied, relative to critical cells. This is more clinically relevant than providing a temperature, as the latter is entirely theoretical, leaving the embryologist with a problem in deciding what temperature is safe.

No 6. 2005 697–710.

This only applies to a simple lens. The Saturn 5 Active objective is a complex compound lens which is corrected for astigmatism, so the laser is focused correctly everywhere in its range of movement. This is easily demonstrated by looking at the pilot laser diffraction rings as the beam is moved. Any focus error would be obvious as the ring pattern would visibly change. Furthermore, it has always been a routine requirement that all parts of the field of view are in sharp focus. The same is true for the laser.

No. Initial alignment is carried out once at installation. The laser position should be checked before each procedure, and this takes two seconds. A full calibration can be done from time-to-time to ensure optimal alignment and this takes 30 seconds. This is a very simple procedure and worthwhile, to minimize damaging the embryo.

Yes, if it is the same model of microscope. If it is a different model then most parts can be transferred, but a different mirror module will be required. Use the fibre cleaning kit 6-46-590 for installation.

Yes, the Saturn 3 and Saturn 3 Active can be upgraded to Saturn 5 or Saturn 5 Active with the purchase of parts.

We will offer service support for Saturn 3 lasers while-ever parts are in stock. However, we cannot guarantee parts availability from November 2019 onwards.
