WHY BLUE LASERS? COLOR SENSITIVITY OF THE HUMAN EYE Normalised absorbance 100 50 0 BLUE LASER LIGHT DOESN T PENETRATE SKIN AS DEEPLY AS LIGHT OF LONGER WAVELENGTHS.

$Unlike the cones, rods are more sensitive to blue light and are not sensitive to wavelengths 1500 L CONES greater than 640 nm, the red S CONES R M CONES fraction of the visible spectrum.$ If the human eye is exposed to less 500 600 700 1000 light than normal, the reception Wavelength (nm) changes from photopic to scotopic sight.

If the human eye is exposed to less 500 600 700 1000 light than normal, the reception Wavelength (nm) changes from photopic to scotopic sight.

2 WHY BLUE LASERS? COLOR SENSITIVITY OF THE HUMAN EYE Normalised absorbance BLUE LASER LIGHT DOESN T PENETRATE SKIN AS DEEPLY AS LIGHT OF LONGER WAVELENGTHS. IT PRODUCES LESS SCATTERING AND LESS DIFFUSE REFLECTIONS The human retina contains approximatively 120 millions rods and only 6 millions cone receptors, which, when stimulated by light, send signals to the brain. These signals are subsequently interpreted as vision. Rods and cones are not equally sensitive to visible wavelengths of light. Unlike the cones, rods are more sensitive to blue light and are not sensitive to wavelengths 1500 L CONES greater than 640 nm, the red S CONES R M CONES fraction of the visible spectrum. If the human eye is exposed to less light than normal, the reception Wavelength (nm) changes from photopic to scotopic sight. This increases the sensitivity of the human eye to blue light by a factor of 10 or more, whereas sensitivity for green increases only by a factor of 2 or less and for red it is reduced to less of even more violett blue cyan green yellow red ABSORPTION CURVES NORMALIZED AT 100% FOR THE DIFFERENT RECEPTOR CELLS IN FUNCTION OF THE WAVELENGTH OF THE LIGHT. (R=RODS, S CONES =BLUE, M CONES =GREEN, L CONES =RED) The best working environment for blue lasers is a dimmed room. This is the case in a CT or linac room. All of this has a positive contribution to the external beam treatment process and to the treatment quality. The user will spend less time aligning of the patient during the treatment or during a QA process.

KEy POINTS BLUE VISION L aser Clearest lines Finest lines Human skin refl ects blue light better APOLLO ROOM LASERS HIGH PRECISION TOOLS FOR PATIENT SETUP AND IMPROVED TREATMENT QUALITY Precise, accurate and reproducible patient positioning is paramount to the success of radiation therapy treatments. Combined with on board imaging systems the patient positioning lasers provide an interface between the patient and the treatment delivery system. Room lasers are necessary tools for aligning the patient, daily reference isocenter adjustments, and assuring optimized isocenter accuracy for your linear accelerator. The LAP APOLLOblue lasers deliver the highest precision, accuracy and reproducibility: with their long lines and 6 degrees of remote controlled freedom they are ideally suited for today s advanced treatments. APOLLOblue, THE FUTURE Because of the shorter wavelength, blue laser light penetrates organic materials and skin less than red or green laser light. Scattering and diff use refl ections such as interactions with oxygenated blood are reduced. The longer wavelength of red and green lasers, leads correspondingly, to an increase in the penetration depth.

4 UNIQUE OPTICS Lasers and optics are the foundation of our business. LAP uses only the highest quality components. Very few off the shelf components are used in LAP s products with many components being manufactured and designed specifi cally for LAP applications. HIGHLY POLISHED ANTI-REFLECTIVE GL ASS LAP roomlasers are equipped with extremely stable highly polished and extra fl attened plane glass windows. They have a very low and constant dispersion to assure a fi ne laser line. The glass is anti-refl ective to avoid interference from the beam. normal glas planed glass with antireflection coating L AP SUPERPRISM LAP APOLLOblue avoids the pitfalls of two separate lines forming a cross by using one singular element: a prism, manufactured to split one beam into two perpendicular lines. This confi guration allows LAP APOLLOblue room lasers to use one window only, making them the most compact systems. As the beam forming takes place before the prism and its surface antirefl ection coating is selcted for the laser s wavelength, focussing of the crosshair has virtually no infl uence on rectangularity or brightness distribution a real superprism. LAP SINGLE FOCUS Due to the singular prism, focussing of both lines of the laser cross is handled by a single adjustment drive.

5 LINE QUALITY MAKING THE DIFFERENCE When using a treatment or imaging system the isocenter must be precisely verifi ed. The LAP APOLLOblue positioning lasers project ultra-fi ne laser lines denoting the isocenter of these systems so that the patient can be quickly and accurately placed on the treatment couch in a reproducible position. LAP APOLLOblue lasers set the highest standard when it comes to line quality, stability, reliability and ease of use. EASE OF ADJUSTMENT During the installation of the treatment machine the APOLLOblue lasers are adjusted so that their LINE WIDTH - FWHM Full width at half maximum (FWHM) is defi ned as the width across the brightness profi le when it drops to half its peak value. This is how the line width for LAP lasers is measured. It is a simple and Brightness 100 % 50 % Line width FWHM respective laser lines precisely intersect the isocenter.
