Magnification in Electrolysis plays a big role in identification of the the hair follicle roots and the hair pores. If the correct insertion is not done then the roots escape the electrolysis needle and are not destroyed. This is the most common cause of the failure of the electrolysis session. This is usually presents with many hairs follicle ingrowths as the hair roots are not destroyed but in effect the hairs are just plucked as the electrolysis needle was not able to reach the root to cause destruction of the hair follicle.
This becomes even more problematic when fine hairs (downy hairs or hair peach fuzz) is being removed as they have even more small hair pore and correct insertion becomes even more problematic.
The various modes of magnifications used in electrolysis are:
Also known as low-vision lighted magnifiers. This is the most common device available in the electrolysis clinics. We have found this device as the most useless. This device uses a single convex lens for magnification and has limitation of magnification of upto 2 times at the maximum. If we try to have a stronger lens, then it gives rise to distortion of the image and also shorter working distance between the lens and the skin making it difficult to use the epilator probe and forceps. Also, using this device for a long time is a single session gives to lot of strain on the neck. Though these devices give good illumination. The field of vision is limited in Magnifying lamp.
These are compound lenses, used for higher magnifications to control optical aberration. The magnification which can be achieved with magnifying loupes is between 2x to 6x, but the higher magnification comes at a cost of smaller field of vision. The higher magnification loupes also become bulkier and heavy. Since we have wear the magnifying loupes for long times depending upon the session of electrolysis, it can sometimes become lot of strain on eyes. One has to bend the neck with use of magnifying loupes which is also lot of stress on neck for longer electrolysis sessions.
These magnification loupes are available in either 2.5x, 4x, or 6x magnification.
A 4x or 5x magnification surgical loupe reveals incredible detail but provides a small field of view (30mm wide) and your working distance has to be maintained more accurately because of narrower depth of field (area in focus). Choose a 4x or 5x loupe if you want to focus on a narrow work area and need to see the details that higher magnification affords.
The lower 2.5x magnification results in a wider field of view (50mm), allowing you to monitor a broader work area. Because of the greater depth of field, the 2.5x surgical loupes provide for more freedom of movement as they are less sensitive to changes in your working distance. People below 5'-7" in height usually need a working distance of 340mm (250-375mm) and those taller usually need a working distance of 420mm (300-450mm).
The best thing about the loupes is that you have a lot more freedom to move. The drawback of the loupes is they just don’t have the power of the microscope.
A surgical microscope has a much costlier than a pair of surgical loupes.
In terms of magnification there is nothing to surpass it. There is 6x, 10x, 16x and 25x magnification.
We are using Labomed Prima Operating Microscope at Reyuva Hair Electrolysis. It is one of the top line operating microscope with LED light source and 5 step magnification with tiltable head and also HD camera for real time display of the hair removal.
General concepts of magnification
What does 'Diopter' mean?
When looking at various magnifiers, you'll come across the term 'diopter'. This refers to the amount of curvature a lens will have. More curvature means a thicker lens, more magnification and a higher diopter number.
To find the magnification level of a lens, simply divide its diopter by 4, and add 1. For example, if you're looking at a 3-diopter lens, it's magnification = ¾ + 1... or .75 + 1 = 1.75x.
Objects viewed under a 3 diopter lens will appear 175% bigger than normal.
A 5-diopter lens = 5/4 + 1... or 1.25 + 1 = 2.25x.
Objects viewed under a 5 diopter lens will appear 225% bigger than normal.
What is the Power of the Lens?
The diopter is the unit of measure for the refractive power of a lens. The power of a lens is defined as the reciprocalof its focal length in meters, or D = 1/f, where D is the power in diopters and f is the focal length in meters.
- A lens with a focal length of two meters has a power of one-half diopter because the reciprocal of two is one-half or D = 1/2f
- A focal length of one-tenth meter would result in a power of 10 diopters. Disregarding thickness, the power of a lens is determined by combining the powers of the front and back surfaces:Dn = D1 + D2
- A lens with a front surface power of +9.00 and a back surface power of 6.00 would have a power of +3.00
Lens surface power can be found with the index of refraction and radius of curvature. The formula for surface power is
Ds = (u-1)/r, where u is the index of refraction and r the radius of curvature in meters.
so power in the combination of the lenses as in operating microscope is
Dn = D1 + D2
Where Dn is the final power of the combination of the two lenses D1 and D2
What does focal length mean?
Focal length is defined as the distance from the lens to the point where an object is in focus (focal point) and it becomes important if you need space above the object in which to work. It's kind of like shining a flashlight on a dark wall. As you move the flashlight (magnifier) closer to the wall, you are reducing its distance (focal length). As you move the flashlight back from the wall, the distance (focal length) increases. Unfortunately, you can't have lots of magnification and lots of room below the lens (focal length). If you need lots of space to work, you won't have as much magnification available. If you don't need much working space, you can get stronger magnification, and in fact, magnifiers with higher power are generally reserved for close-in inspection and measurement... 3 diopter = 1.75x magnification at 13” focal length 5 diopter = 2.25x magnification at 8” focal length 7 diopter = 2.75x magnification at 5.5” focal length As a general rule of thumb, when your magnification gets larger, your lens and focal length get smaller.
What is meant by 'Field-Of-View' (FOV)?
The field of view is the size of the magnified area that is in focus under the lens. The higher your magnification, the smaller your field-of-view. Lets go back to our flashlight example. As you move the flashlight closer to the wall (stronger magnification), the spot of light (field-of-view) will shrink.
