Types of lasersand their uses

The thermal effect on the hair is low and ensures a high level of intensity. This laser is recommended for long-term hair removal on dark skin or deeply rooted hair.

The Alexandrite is a semi-precious stone that filters light at a wavelength of 755 nm. This wavelength corresponds to the maximum absorption peak of melanin. As a result, the light beam penetrates the hair root very precisely without needing a high level of intensity.

CMOS Sensor Size: The physical dimensions of the image sensor in the camera, typically expressed in inches. The sensor size affects the field of view, depth of field, and image quality.

What are the 3types of lasers

In short…Epilia has opted for the latest generation of state-of-the-art lasers: Alexandrite lasers from the Candela brand. This type of laser is highly efficient and guarantees permanent hair removal under optimal safety and hygiene conditions.

The lower absorption by melanin is both an advantage (tanning and skin pigmentation are not greatly affected) and a disadvantage (lighter and finer hairs resist the treatment).

Therefore, the results are often temporary and disappointing for the patient, and it also has a significant risk of burn marks.

The Nd-Yag laserNd-Yag is the most appropriate laser for the treatment of dark skin types. This laser works at a wavelength of 1064 nm, which has a low level of absorption by melanin and therefore the light beam penetrates deeper into the hair root.

How manytypes oflaser

The laser targets the pigmentation of the hair (i.e. the melanin). It emits a very concentrated beam of light at a very precise wavelength. That light is converted into heat when it is absorbed by the melanin. When the pigment in the hair follicle (sac from which the hair grows) is hit, the hair and its root are destroyed, which means that it can never grow back.

Unlike IPL, laser treatment is only carried out by specially trained medical personnel. Thanks to compulsory training, the laser procedure is a highly controlled technique and is also the subject of numerous efficiency and safety studies. Laser hair removal is the only technique that can guarantee you a permanent, safe and effective solution for unwanted hair growth.

IPLThe lamps used in IPL provide less selective, less powerful and more diffused light than lasers. Since the pulsed light is much less strong it only weakens the hair follicles, and therefore cannot guarantee a permanent result.

This wavelength has a low level of absorption by melanin and therefore the light beam penetrates deeper into the hair root.

The Alexandrite laserEpilia chose to work with the Alexandrite laser from Candela, which is currently the world leader in the field of dermatological and aesthetic lasers.

This is a conscious choice resulting from thorough research. This blog provides an overview of all of the different types of lasers and methods on the market.

Although this is a promising technique, the Diode Laser is not yet fully developed, so a lot of sessions are needed for a good result.

Focal Length: The distance between the lens and the image sensor, measured in millimeters. A shorter focal length provides a wider field of view, while a longer focal length offers a narrower field of view.

In our tool, you can effortlessly simulate real-world conditions for actual cameras to plan your CCTV installation. This comprehensive CCTV Camera Planner provides an intuitive interface for professionals and enthusiasts alike, making it simpler than ever to design and optimize your surveillance system with precision and ease.

All scientific studies agree that the Alexandrite is currently the laser that offers the most convincing results on fair and medium skin types.

… versus laserThe laser, on the other hand, emits a powerful, more selective energy beam that completely destroys the hair follicle. This makes the treatment truly permanent.

It is important to be well informed about the different techniques of permanent hair removal before you make your choice.

Why is this so important?The initial consultation is an information session that allows you to find out everything you need to know about laser hair removal.The Laser Technician will check whether you meet all the conditions to ensure the laser works optimally (skin type, hair colour, age, any hormonal concerns, etc.).

Field of View (FoV): The area visible to the camera lens, measured in degrees. A wider FoV captures more of the scene but may reduce image quality. A narrower FoV provides greater detail but covers less area.

Calculate the camera's field of view by entering the focal length and selecting the sensor from the list to find out the horizontal and vertical FOV. For cameras with a variable focal length, you can enter a range, allowing the calculator to compute the FOV for each zoom setting.

Are there other techniques available for permanent or long-term hair removal?IPL technology, or Intense Pulsed Light, is often confused with laser hair removal. However, these two hair removal techniques are very different, both in terms of safety and effectiveness.

The Diode LaserThe Diode Laser, which is much less efficient than the Alexandrite, has the advantage that it is cheaper and more compact. This also makes it easy to transport. The Diode operates on a wavelength from 810 to 980 nm, so it has a wider spectrum than the Alexandrite and the Nd-Yag.

Note: The calculator assumes the camera is mounted horizontally. The actual field of view may vary depending on the camera's orientation and the lens distortion.
